You can set the NWA/WAC to operate in either standalone AP or managed AP mode. When the NWA/
WAC is in standalone AP mode, it can serve as a normal AP, as an RF monitor to search for rouge APs to
help eliminate network threats (if it supports monitor mode and rogue APs detection), or even as a root
AP or a wireless repeater to establish wireless links with other APs in a WDS (Wireless Distribution System). A
WDS is a wireless connection between two or more APs.
Your NWA/WAC’s business-class reliability, SMB features, and centralized wireless management make it
ideally suited for advanced service delivery in mission-critical networks. It uses Multiple BSSID and VLAN
to provide simultaneous independent virtual APs. Additionally, innovations in roaming technology and
QoS features eliminate voice call disruptions.
The NWA/WAC controls network access with Media Access Control (MAC) address filtering, and rogue
Access Point (AP) detection. It also provides a high level of network traffic security, supporting IEEE
802.1x, Wi-Fi Protected Access 2 and Wired Equivalent Privacy (WEP) data encryption.
Your NWA/WAC is easy to install, configure and use. The embedded Web-based configurator enables
simple, straightforward management and maintenance. See the Quick Start Guide for how to make
hardware connections.

Chapter 1 Introduction
1.1.1 Management Mode
The NWA/WAC is a unified AP and can work either in standalone AP mode or in managed AP mode. If
the NWA/WAC and a Zyxel AP controller, such as the NXC2500 or NXC5500, are in the same subnet, it will
be managed by the controller automatically.
An AP controller uses Control And Provisioning of Wireless Access Points (CAPWAP, see RFC 5415) to
discover and configure multiple managed APs.
To set the NWA/WAC to be managed by an AP controller in a different subnet or change between
management modes, use the AC (AP Controller) Discovery screen (see Section 5.4 on page 68).

When the NWA/WAC is in standalone AP mode and connects to a DHCP server, it uses the IP address
assigned by the DHCP server. Otherwise, the NWA/WAC uses the default static management IP address
(192.168.1.2). You can use the AC Discovery screen to have the NWA/WAC work as a managed AP.
When the NWA/WAC is in managed AP mode, it acts as a DHCP client and obtains an IP address from
the AP controller. It can be configured ONLY by the AP controller. To change the NWA/WAC back to
standalone AP mode, use the Reset button to restore the default configuration. Alternatively, you need
to check the AP controller for the NWA/WAC’s IP address and use FTP to upload the default
configuration file at conf/system-default.conf to the NWA/WAC and reboot the device.
1.1.2 MBSSID
A Basic Service Set (BSS) is the set of devices forming a single wireless network (usually an access point
and one or more wireless clients). The Service Set IDentifier (SSID) is the name of a BSS. In Multiple BSS
(MBSSID) mode, the NWA/WAC provides multiple virtual APs, each forming its own BSS and using its own
individual SSID profile.
You can configure multiple SSID profiles, and have all of them active at any one time.
You can assign different wireless and security settings to each SSID profile. This allows you to
compartmentalize groups of users, set varying access privileges, and prioritize network traffic to and
from certain BSSs.
To the wireless clients in the network, each SSID appears to be a different access point. As in any wireless
network, clients can associate only with the SSIDs for which they have the correct security settings.
For example, you might want to set up a wireless network in your office where Internet telephony (VoIP)
users have priority. You also want a regular wireless network for standard users, as well as a ‘guest’
wireless network for visitors. In the following figure, VoIP_SSID users have QoS priority, SSID01 is the wireless
network for standard users, and Guest_SSID is the wireless network for guest users. In this example, the
guest user is forbidden access to the wired Land Area Network (LAN) behind the AP and can access
only the Internet.

Figure 1 Multiple BSSs
1.1.3 Dual-Radio
Some of the NWA/WAC models are equipped with dual wireless radios. This means you can configure
two different wireless networks to operate simultaneously.
Note: A different channel should be configured for each WLAN interface to reduce the
effects of radio interference.
You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz
band for time sensitive traffic like high-definition video, music, and gaming.

1.1.4 Root AP
In Root AP mode, the NWA/WAC (Z) can act as the root AP in a wireless network and also allow
repeaters (X and Y) to extend the range of its wireless network at the same time. In the figure below,
both clients A, B and C can access the wired network through the root AP.
Figure 3 Root AP Application
On the NWA/WAC in Root AP mode, you can have multiple SSIDs active for regular wireless connections
and one SSID for the connection with a repeater (repeater SSID). Wireless clients can use either SSID to
NWA / WAC Series User’s Guide
15
Chapter 1 Introduction
associate with the NWA/WAC in Root AP mode. A repeater must use the repeater SSID to connect to
the NWA/WAC in Root AP mode.
When the NWA/WAC is in Root AP mode, repeater security between the NWA/WAC and other repeater
is independent of the security between the wireless clients and the AP or repeater. When repeater
security is enabled, both APs and repeaters must use the same pre-shared key. See Section 6.2 on page
71 and Section 10.2 on page 113 for more details.
Unless specified, the term “security settings” refers to the traffic between the wireless clients and the AP.
At the time of writing, repeater security is compatible with the NWA/WAC only.
1.1.5 Repeater
The NWA/WAC can act as a wireless network repeater to extend a root AP’s wireless network range,
and also establish wireless connections with wireless clients.
Using Repeater mode, your NWA/WAC can extend the range of the WLAN. In the figure below, the
NWA/WAC in Repeater mode (Z) has a wireless connection to the NWA/WAC in Root AP mode (X)
which is connected to a wired network and also has a wireless connection to another NWA/WAC in
Repeater mode (Y) at the same time. Z and Y act as repeaters that forward traffic between associated
wireless clients and the wired LAN. Clients A and B access the AP and the wired network behind the AP
through repeaters Z and Y.
Figure 4 Repeater Application
When the NWA/WAC is in Repeater mode, repeater security between the NWA/WAC and other
repeater is independent of the security between the wireless clients and the AP or repeater. When
repeater security is enabled, both APs and repeaters must use the same pre-shared key. See Section 6.2
on page 71 and Section 10.2 on page 113 for more details.
Once the security settings of peer sides match one another, the connection between devices is made.
NWA / WAC Series User’s Guide

At the time of writing, repeater security is compatible with the NWA/WAC only.
1.2 Ways to Manage the NWA/WAC
You can use the following ways to manage the NWA/WAC.
Web Configurator
The Web Configurator allows easy NWA/WAC setup and management using an Internet browser. This
User’s Guide provides information about the Web Configurator.
Command-Line Interface (CLI)
The CLI allows you to use text-based commands to configure the NWA/WAC. You can access it using
remote management (for example, SSH or Telnet). See the Command Reference Guide for more
information.
File Transfer Protocol (FTP)
This protocol can be used for firmware upgrades and configuration backup and restore.
Simple Network Management Protocol (SNMP)
The NWA/WAC can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide.
1.3 Good Habits for Managing the NWA/WAC
Do the following things regularly to make the NWA/WAC more secure and to manage it more
effectively.
• Change the password often. Use a password that’s not easy to guess and that consists of different
types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working
configuration may be useful if the device becomes unstable or even crashes. If you forget your
password, you will have to reset the NWA/WAC to its factory default settings. If you backed up an
earlier configuration file, you won’t have to totally re-configure the NWA/WAC; you can simply restore
your last configuration.

1.5.2 Phone Port
Connect a digital telephone to the RJ-45 PHONE port at the bottom of the NWA to forward voice traffic
to/from the telephone switchboard that is connected to the RJ-45 PHONE port on the back of the NWA.
The NWA does not support VoIP (Voice over Internet Protocol) and the PHONE port is NOT for making
calls over the regular networking network (PSTN), either.
1.5.3 Console Port
To use the CLI commands to configure the NWA, connect an RJ-45-to-DB-9 cable to the PHONE port at
the bottom of the NWA.

1.7 Starting and Stopping the NWA/WAC
Here are some of the ways to start and stop the NWA/WAC.
Always use Maintenance > Shutdown or the shutdown command
before you turn off the NWA/WAC or remove the power. Not doing so
can cause the firmware to become corrupt.
Table 11 Starting and Stopping the NWA/WAC
METHOD
DESCRIPTION
Turning on the power
A cold start occurs when you turn on the power to the NWA/WAC. The NWA/WAC
powers up, checks the hardware, and starts the system processes.
Rebooting the NWA/
WAC
A warm start (without powering down and powering up again) occurs when you use the
Reboot button in the Reboot screen or when you use the reboot command. The NWA/
WAC writes all cached data to the local storage, stops the system processes, and then
does a warm start.
Using the RESET button
If you press the RESET button on the back of the NWA/WAC, the NWA/WAC sets the
configuration to its default values and then reboots. See Section 20.6 on page 197 for
more information.

CHAPTER 5
Network
5.1 Overview
This chapter describes how you can configure the management IP address and VLAN settings of your
NWA/WAC.
The Internet Protocol (IP) address identifies a device on a network. Every networking device (including
computers, servers, routers, printers, etc.) needs an IP address to communicate across the network.
These networking devices are also known as hosts.
Figure 29 IP Setup
The figure above illustrates one possible setup of your NWA/WAC. The gateway IP address is 192.168.1.1
and the managed IP address of the NWA/WAC is 192.168.1.2 (default), but if the NWA/WAC is assigned
an IP address by a DHCP server, the default (192.168.1.2) will not be used. The gateway and the NWA/
WAC must belong in the same IP subnet to be able to communicate with each other.
5.1.1 Management Mode
This discusses using the NWA/WAC in management mode, which determines whether the NWA/WAC is
used in its standalone mode, or as part of a Control And Provisioning of Wireless Access Points (CAPWAP)
network.
About CAPWAP
The NWA/WAC supports CAPWAP. This is Zyxel’s implementation of the CAPWAP protocol (RFC 5415).
The CAPWAP dataflow is protected by Datagram Transport Layer Security (DTLS).
The following figure illustrates a CAPWAP wireless network. You (U) configure the AP controller (C), which
then automatically updates the configurations of the managed APs (M1 ~ M4).
NWA / WAC Series User’s Guide
61
Chapter 5 Network
Figure 30 CAPWAP Network Example
Note: The NWA/WAC can be a standalone AP (default), or a CAPWAP managed AP.
CAPWAP Discovery and Management
The link between CAPWAP-enabled access points proceeds as follows:
An AP in managed AP mode joins a wired network (receives a dynamic IP address).
The AP sends out a discovery request, looking for a CAPWAP AP controller.
If there is an AP controller on the network, it receives the discovery request. If the AP controller is in
Manual mode it adds the details of the AP to its Unmanaged Access Points list, and you decide which
available APs to manage. If the AP controller is in Always Accept mode, it automatically adds the AP to
its Managed Access Points list and provides the managed AP with default configuration information, as
well as securely transmitting the DTLS pre-shared key. The managed AP is ready for association with
wireless clients.
Managed AP Finds the Controller
A managed NWA/WAC can find the controller in one of the following ways:
• Manually specify the controller’s IP address in the Web Configurator’s AC (AP Controller) Discovery
screen.
• Get the controller’s IP address from a DHCP server with the controller’s IP address configured as
option 138.
• Get the controller’s IP address from a DNS server SRV (Service) record.
• Broadcasting to discover the controller within the broadcast domain.
Note: The AP controller needs to have a static IP address. If it is a DHCP client, set the DHCP
server to reserve an IP address for the AP controller.
NWA / WAC Series User’s Guide
62
Chapter 5 Network
CAPWAP and IP Subnets
By default, CAPWAP works only between devices with IP addresses in the same subnet.
However, you can configure CAPWAP to operate between devices with IP addresses in different
subnets by doing the following.
• Activate DHCP. Your network’s DHCP server must support option 138 defined in RFC 5415.
• Configure DHCP option 138 with the IP address of the CAPWAP AP controller on your network.
DHCP Option 138 allows the CAPWAP management request (from the AP in managed AP mode) to
reach the AP controller in a different subnet, as shown in the following figure.
Figure 31 CAPWAP and DHCP Option 138
Notes on CAPWAP
This section lists some additional features of Zyxel’s implementation of the CAPWAP protocol.
• When the AP controller uses its internal Remote Authentication Dial In User Service (RADIUS) server,
managed APs also use the AP controller’s authentication server to authenticate wireless clients.
• If a managed AP’s link to the AP controller is broken, the managed AP continues to use the wireless
settings with which it was last provided.
5.1.2 What You Can Do in this Chapter
• The IP Setting screen (Section 5.2 on page 64) configures the NWA/WAC’s LAN IP address.
• The VLAN screen (Section 5.3 on page 65) configures the NWA/WAC’s VLAN settings.
• The AC (AP Controller) Discovery screen (Section 5.3 on page 65) configures the NWA/WAC’s AP
Controller settings.

5.3 VLAN
This section discusses how to configure the NWA/WAC’s VLAN settings.
NWA / WAC Series User’s Guide

Chapter 5 Network
Figure 33 Management VLAN Setup
In the figure above, to access and manage the NWA/WAC from computer A, the NWA/WAC and
switch B’s ports to which computer A and the NWA/WAC are connected should be in the same VLAN.
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable
logical broadcast domain. In traditional switched environments, all broadcast packets go to each and
every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.
IEEE 802.1Q Tag
The IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN
membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user priority.
The VLAN ID associates a frame with a specific VLAN and provides the information that devices need to
process the frame across the network.

Wireless
6.1 Overview
This chapter discusses how to configure the wireless network settings in your NWA/WAC.
The following figure provides an example of a wireless network.
Figure 36 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B are called
wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the
printer) or with the Internet. Your NWA/WAC is the AP.
6.1.1 What You Can Do in this Chapter
• The AP Management screen (Section 6.2 on page 71) manages the NWA/WAC’s general wireless
settings.
• The MON Mode screen (Section 6.3 on page 74) allows you to assign APs either to the rogue AP list or
the friendly AP list.
• The Load Balancing screen (Section 6.4 on page 76) configures network traffic load balancing
between the APs and the NWA/WAC.
• The DCS screen (Section 6.5 on page 79) configures dynamic radio channel selection.

6.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
Station / Wireless Client
A station or wireless client is any wireless-capable device that can connect to an AP using a wireless
signal.
Dynamic Channel Selection (DCS)
Dynamic Channel Selection (DCS) is a feature that allows an AP to automatically select the radio
channel upon which it broadcasts by scanning the area around it and determining what channels are
currently being used by other devices.
Load Balancing (Wireless)
Wireless load balancing is the process where you limit the number of connections allowed on an wireless
access point (AP) or you limit the amount of wireless traffic transmitted and received on it so the AP
does not become overloaded.

Mode
Use this section to configure wireless network traffic load balancing between the managd
APs in this group.
Select a mode by which load balancing is carried out.
Select By Station Number to balance network traffic based on the number of specified
stations connected to the NWA/WAC.
Select By Traffic Level to balance network traffic based on the volume generated by the
stations connected to the NWA/WAC.
Select By Smart Classroom to balance network traffic based on the number of specified
stations connected to the NWA/WAC. The NWA/WAC ignores association request and
authentication request packets from any new station when the maximum number of
stations is reached.
If you select By Station Number or By Traffic Level, once the threshold is crossed (either the
maximum station numbers or with network traffic), the NWA/WAC delays association
request and authentication request packets from any new station that attempts to make a
connection. This allows the station to automatically attempt to connect to another, less
burdened AP if one is available.
Max Station
Number
Enter the threshold number of stations at which the NWA/WAC begins load balancing its
connections.
Traffic Level
Select the threshold traffic level at which the NWA/WAC begins load balancing its
connections (Low, Medium, High).
The maximum bandwidth allowed for each level is:
•
•
•
Disassociate
station when
overloaded
Low - 11 Mbps,
Medium - 23 Mbps
High - 35M bps
This function is enabled by default and the disassociation priority is always Signal Strength
when you set Mode to By Smart Classroom.
Select this option to disassociate wireless clients connected to the AP when it becomes
overloaded. If you do not enable this option, then the AP simply delays the connection until
it can afford the bandwidth it requires, or it transfers the connection to another AP within its
broadcast radius.
The disassociation priority is determined automatically by the NWA/WAC and is as follows:
•
•
Idle Timeout - Devices that have been idle the longest will be kicked first. If none of the
connected devices are idle, then the priority shifts to Signal Strength.
Signal Strength - Devices with the weakest signal strength will be kicked first.
Note: If you enable this function, you should ensure that there are multiple APs
within the broadcast radius that can accept any rejected or kicked
wireless clients; otherwise, a wireless client attempting to connect to an
overloaded AP will be disassociated permanently and never be allowed to
connect.

6.4.1 Disassociating and Delaying Connections
When your AP becomes overloaded, there are two basic responses it can take. The first one is to
“delay” a client connection. This means that the AP withholds the connection until the data transfer
throughput is lowered or the client connection is picked up by another AP. If the client is picked up by
another AP then the original AP cannot resume the connection.
For example, here the AP has a balanced bandwidth allotment of 6 Mbps. If laptop R connects and it
pushes the AP over its allotment, say to 7 Mbps, then the AP delays the red laptop’s connection until it
can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to spare.
Figure 41 Delaying a Connection
The second response your AP can take is to kick the connections that are pushing it over its balanced
bandwidth allotment.
Figure 42 Kicking a Connection
Connections are kicked based on either idle timeout or signal strength. The NWA/WAC first looks to see
which devices have been idle the longest, then starts kicking them in order of highest idle time. If no
connections are idle, the next criteria the NWA/WAC analyzes is signal strength. Devices with the
weakest signal strength are kicked first.

6.6 Technical Reference
The following section contains additional technical information about the features described in this
chapter.
Dynamic Channel Selection
When numerous APs broadcast within a given area, they introduce the possibility of heightened radio
interference, especially if some or all of them are broadcasting on the same radio channel. If the
interference becomes too great, then the network administrator must open his AP configuration options
and manually change the channel to one that no other AP is using (or at least a channel that has a
lower level of interference) in order to give the connected stations a minimum degree of interference.
Dynamic channel selection frees the network administrator from this task by letting the AP do it
automatically. The AP can scan the area around it looking for the channel with the least amount of
interference.
In the 2.4 GHz spectrum, each channel from 1 to 13 is broken up into discrete 22 MHz segments that are
spaced 5 MHz apart. Channel 1 is centered on 2.412 GHz while channel 13 is centered on 2.472 GHz.
NWA / WAC Series User’s Guide
79
Chapter 6 Wireless
Figure 44 An Example Three-Channel Deployment
Three channels are situated in such a way as to create almost no interference with one another if used
exclusively: 1, 6 and 11. When an AP broadcasts on any of these three channels, it should not interfere
with neighboring APs as long as they are also limited to same trio.
Figure 45 An Example Four-Channel Deployment
However, some regions require the use of other channels and often use a safety scheme with the
following four channels: 1, 4, 7 and 11. While they are situated sufficiently close to both each other and
the three so-called “safe” channels (1,6 and 11) that interference becomes inevitable, the severity of it is
dependent upon other factors: proximity to the affected AP, signal strength, activity, and so on.
Finally, there is an alternative four channel scheme for ETSI, consisting of channels 1, 5, 9, 13. This offers
significantly less overlap that the other one.
Figure 46 An Alternative Four-Channel Deployment
Load Balancing
Because there is a hard upper limit on an AP’s wireless bandwidth, load balancing can be crucial in
areas crowded with wireless users. Rather than let every user connect and subsequently dilute the
available bandwidth to the point where each connecting device receives a meager trickle, the load
balanced AP instead limits the incoming connections as a means to maintain bandwidth integrity.
There are three kinds of wireless load balancing available on the NWA/WAC:
NWA / WAC Series User’s Guide
80
Chapter 6 Wireless
Load balancing by station number limits the number of devices allowed to connect to your AP. If you
know exactly how many stations you want to let connect, choose this option.
For example, if your company’s graphic design team has their own AP and they have 10 computers,
you can load balance for 10. Later, if someone from the sales department visits the graphic design
team’s offices for a meeting and he tries to access the network, his computer’s connection is delayed,
giving it the opportunity to connect to a different, neighboring AP. If he still connects to the AP
regardless of the delay, then the AP may boot other people who are already connected in order to
associate with the new connection.
Load balancing by smart classroom also limits the number of devices allowed to connect to your AP.
But any new connections will be just rejected when the AP is overloaded.
Load balancing by traffic level limits the number of connections to the AP based on maximum
bandwidth available. If you are uncertain as to the exact number of wireless connections you will have
then choose this option. By setting a maximum bandwidth cap, you allow any number of devices to
connect as long as their total bandwidth usage does not exceed the configured bandwidth cap
associated with this setting. Once the cap is hit, any new connections are rejected or delayed provided
that there are other APs in range.
Imagine a coffee shop in a crowded business district that offers free wireless connectivity to its
customers. The coffee shop owner can’t possibly know how many connections his AP will have at any
given moment. As such, he decides to put a limit on the bandwidth that is available to his customers but
not on the actual number of connections he allows. This means anyone can connect to his wireless
network as long as the AP has the bandwidth to spare. If too many people connect and the AP hits its
bandwidth cap then all new connections must basically wait for their turn or get shunted to the nearest
identical AP.

AP Profile
8.1 Overview
This chapter shows you how to configure preset profiles for the NWA/WAC.
8.1.1 What You Can Do in this Chapter
• The Radio screen (Section 8.2 on page 90) creates radio configurations that can be used by the APs.
• The SSID screen (Section 8.3 on page 96) configures three different types of profiles for your
networked APs.
8.1.2 What You Need To Know
The following terms and concepts may help as you read this chapter.
Wireless Profiles
At the heart of all wireless AP configurations on the NWA/WAC are profiles. A profile represents a group
of saved settings that you can use across any number of connected APs. You can set up the following
wireless profile types:
• Radio - This profile type defines the properties of an AP’s radio transmitter. You can have a maximum
of 32 radio profiles on the NWA/WAC.
• SSID - This profile type defines the properties of a single wireless network signal broadcast by an AP.
Each radio on a single AP can broadcast up to 8 SSIDs. You can have a maximum of 32 SSID profiles
on the NWA/WAC.
• Security - This profile type defines the security settings used by a single SSID. It controls the encryption
method required for a wireless client to associate itself with the SSID. You can have a maximum of 32
security profiles on the NWA/WAC.
• MAC Filtering - This profile provides an additional layer of security for an SSID, allowing you to block
access or allow access to that SSID based on wireless client MAC addresses. If a client’s MAC address
is on the list, then it is either allowed or denied, depending on how you set up the MAC Filter profile.
You can have a maximum of 32 MAC filtering profiles on the NWA/WAC.
• Layer-2 Isolation - This profile defines the MAC addresses of the devices that you want to allow the
associated wireless clients to have access to when layer-2 isolation is enabled.
SSID
The SSID (Service Set IDentifier) is the name that identifies the Service Set with which a wireless station is
associated. Wireless stations associating to the access point (AP) must have the same SSID. In other
words, it is the name of the wireless network that clients use to connect to it.
NWA / WAC Series User’s Guide
89
Chapter 8 AP Profile
WEP
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the AP and
the wireless stations associated with it in order to keep network communications private. Both the
wireless stations and the access points must use the same WEP key for data encryption and decryption.
WPA2
WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and
key management than WPA. Key differences between WPA2 and WEP are improved data encryption
and user authentication.
IEEE 802.1x
The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless
stations and encryption key management. Authentication is done using an external RADIUS server.

Select Three-Channel Deployment to limit channel switching to channels 1,6, and 11, the
three channels that are sufficiently attenuated to have almost no impact on one another.
In other words, this allows you to minimize channel interference by limiting channelhopping to these three “safe” channels.
Select Four-Channel Deployment to limit channel switching to four channels. Depending
on the country domain, if the only allowable channels are 1-11 then the NWA/WAC uses
channels 1, 4, 7, 11 in this configuration; otherwise, the NWA/WAC uses channels 1, 5, 9, 13
in this configuration. Four channel deployment expands your pool of possible channels
while keeping the channel interference to a minimum.
Enable 5 GHz DFS
Aware
This field is available only when you select 11a, 11a/n or 11ac in the 802.11 Band field and
set 5 GHz Channel Selection Method to auto.
Select this if your APs are operating in an area known to have RADAR devices. This allows
the devide to downgrade its frequency to below 5 GHz in the event RADAR signal is
detected, thus preventing it from interfering with that signal.
Enabling this forces the AP to select a non-DFS channel.
5 GHz Channel
Selection Method
Select how you want to specify the channels the NWA/WAC switches between for 5 GHz
operation.
Select Auto to have the NWA/WAC automatically select the best channel.
Select manual to select the individual channels the NWA/WAC switches between.
Note: The method is automatically set to auto when no channel is selected or
any one of the previously selected channels is not supported.
Channel ID
This field is available only when you set Channel Selection to DCS and set 5 GHz Channel
Selection Method to manual.
Select the check boxes of the channels that you want the NWA/WAC to use.
Time Interval
Select this option to have the NWA/WAC survey the other APs within its broadcast radius at
the end of the specified time interval.
DCS Time Interval
This field is available when you set Channel Selection to DCS and select the Time Interval
option.
Enter a number of minutes. This regulates how often the NWA/WAC surveys the other APs
within its broadcast radius. If the channel on which it is currently broadcasting suddenly
comes into use by another AP, the NWA/WAC will then dynamically select the next
available clean channel or a channel with lower interference.
Schedule
Select this option to have the NWA/WAC survey the other APs within its broadcast radius at
a specifc time on selected days of the week.
Start Time
Specify the time of the day (in 24-hour format) to have the NWA/WAC use DCS to
automatically scan and find a less-used channel.
Week Days
Select each day of the week to have the NWA/WAC use DCS to automatically scan and
find a less-used channel.
Advanced Settings
Guard Interval
Set the guard interval for this radio profile to either short or long. This option isn’t applicable
if you set 802.11 Band to 11a or 11b/g and/or choose 20 MHz channel width.
The guard interval is the gap introduced between data transmission from users in order to
reduce interference. Reducing the interval increases data transfer rates but also increases
interference. Increasing the interval reduces data transfer rates but also reduces
interference.

Enable A-MPDU
Aggregation
DESCRIPTION
Select this to enable A-MPDU aggregation. This field is not available if you set 802.11 Band
to 11a or 11b/g.
Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with their
802.11n headers and wraps them in a 802.11n MAC header. This method is useful for
increasing bandwidth throughput in environments that are prone to high error rates.
Enable A-MSDU
Aggregation
Select this to enable A-MSDU aggregation. This field is not available if you set 802.11 Band
to 11a or 11b/g.
Mac Service Data Unit (MSDU) aggregation collects Ethernet frames without any of their
802.11n headers and wraps the header-less payload in a single 802.11n MAC header. This
method is useful for increasing bandwidth throughput. It is also more efficient than A-MPDU
except in environments that are prone to high error rates.
RTS/CTS Threshold
Use RTS/CTS to reduce data collisions on the wireless network if you have wireless clients
that are associated with the same AP but out of range of one another. When enabled, a
wireless client sends an RTS (Request To Send) and then waits for a CTS (Clear To Send)
before it transmits. This stops wireless clients from transmitting packets at the same time
(and causing data collisions).
A wireless client sends an RTS for all packets larger than the number (of bytes) that you
enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold to turn RTS/
CTS off.
Beacon Interval
When a wirelessly networked device sends a beacon, it includes with it a beacon interval.
This specifies the time period before the device sends the beacon again. The interval tells
receiving devices on the network how long they can wait in low-power mode before
waking up to handle the beacon. A high value helps save current consumption of the
access point.
DTIM
Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and
multicast packets are transmitted to mobile clients in the Active Power Management
mode. A high DTIM value can cause clients to lose connectivity with the network. This value
can be set from 1 to 255.
Enable Signal
Threshold
Select the check box to use the signal threshold to ensure wireless clients receive good
throughput. This allows only wireless clients with a strong signal to connect to the AP.
Clear the check box to not require wireless clients to have a minimum signal strength to
connect to the AP.
Station Signal
Threshold
Set a minimum client signal strength. A wireless client is allowed to connect to the AP only
when its signal strength is stronger than the specified threshold.
-20 dBm is the strongest signal you can require and -76 is the weakest.
Disassociate
Station Threshold
Set a minimum kick-off signal strength. When a wireless client’s signal strength is lower than
the specified threshold, the NWA/WAC disconnects the wireless client from the AP.
-20 dBm is the strongest signal you can require and -90 is the weakest.
Allow Station
Connection after
Multiple Retries
Select this option to allow a wireless client to try to associate with the AP again after it is
disconnected due to weak signal strength.

Transmission
Mode
DESCRIPTION
Specify how the NWA/WAC handles wireless multicast traffic.
Select Multicast to Unicast to broadcast wireless multicast traffic to all of the wireless clients
as unicast traffic. Unicast traffic dynamically changes the data rate based on the
application’s bandwidth requirements. The retransmit mechanism of unicast traffic
provides more reliable transmission of the multicast traffic, although it also produces
duplicate packets.
Select Fixed Multicast Rate to send multicast traffic to all wireless clients at a single data
rate. You must know the multicast application’s bandwidth requirements and set it in the
following field.
Multicast
Rate(Mbps)
If you set Transmission Mode to Fixed Multicast Rate, select a data rate at which the NWA/
WAC transmits multicast packets to wireless clients. For example, to deploy 4 Mbps video,
select a fixed multicast rate higher than 4 Mbps.

8.3 SSID
The SSID screens allow you to configure three different types of profiles for your networked APs: an SSID
list, which can assign specific SSID configurations to your APs; a security list, which can assign specific
encryption methods to the APs when allowing wireless clients to connect to them; and a MAC filter list,
which can limit connections to an AP based on wireless clients MAC addresses.
8.3.1 SSID List
This screen allows you to create and manage SSID configurations that can be used by the APs. An SSID,
or Service Set IDentifier, is basically the name of the wireless network to which a wireless client can
connect. The SSID appears as readable text to any device capable of scanning for wireless frequencies
(such as the WiFi adapter in a laptop), and is displayed as the wireless network name when a person
makes a connection to it.
To access this screen click Configuration > Object > AP Profile > SSID.
Note: You can have a maximum of 32 SSID profiles on the NWA/WAC.

DESCRIPTION
Create new
Object
Select an object type from the list to create a new one associated with this SSID profile.
Profile Name
Enter up to 31 alphanumeric characters for the profile name. This name is only visible in the
Web Configurator and is only for management purposes. Spaces and underscores are
allowed.
SSID
Enter the SSID name for this profile. This is the name visible on the network to wireless clients.
Enter up to 32 characters, spaces and underscores are allowed.
Security Profile
Select a security profile from this list to associate with this SSID. If none exist, you can use the
Create new Object menu to create one.
Note: It is highly recommended that you create security profiles for all of your SSIDs to
enhance your network security.
MAC Filtering
Profile
Select a MAC filtering profile from the list to associate with this SSID. If none exist, you can use
the Create new Object menu to create one.
MAC filtering allows you to limit the wireless clients connecting to your network through a
particular SSID by wireless client MAC addresses. Any clients that have MAC addresses not in
the MAC filtering profile of allowed addresses are denied connections.
The disable setting means no MAC filtering is used.
Layer-2 Isolation
Profile
Select a layer-2 isolation profile from the list to associate with this SSID. If none exist, you can use
the Create new Object menu to create one.
Layer-2 isolation allows you to prevent wireless clients associated with your NWA/WAC from
communicating with other wireless clients, APs, computers or routers in a network.
The disable setting means no layer-2 isolation is used.
QoS
Select a Quality of Service (QoS) access category to associate with this SSID. Access categories
minimize the delay of data packets across a wireless network. Certain categories, such as
video or voice, are given a higher priority due to the time sensitive nature of their data packets.
QoS access categories are as follows:
disable: Turns off QoS for this SSID. All data packets are treated equally and not tagged with
access categories.
WMM: Enables automatic tagging of data packets. The NWA/WAC assigns access categories
to the SSID by examining data as it passes through it and making a best guess effort. If
something looks like video traffic, for instance, it is tagged as such.
WMM_VOICE: All wireless traffic to the SSID is tagged as voice data. This is recommended if an
SSID is used for activities like placing and receiving VoIP phone calls.
WMM_VIDEO: All wireless traffic to the SSID is tagged as video data. This is recommended for
activities like video conferencing.
WMM_BEST_EFFORT: All wireless traffic to the SSID is tagged as “best effort,” meaning the data
travels the best route it can without displacing higher priority traffic. This is good for activities
that do not require the best bandwidth throughput, such as surfing the Internet.
WMM_BACKGROUND: All wireless traffic to the SSID is tagged as low priority or “background
traffic”, meaning all other access categories take precedence over this one. If traffic from an
SSID does not have strict throughput requirements, then this access category is recommended.
For example, an SSID that only has network printers connected to it.

VLAN ID
Enter a VLAN ID for the NWA/WAC to use to tag traffic originating from this SSID.
Hidden SSID
Select this if you want to “hide” your SSID from wireless clients. This tells any wireless clients in the
vicinity of the AP using this SSID profile not to display its SSID name as a potential connection.
Not all wireless clients respect this flag and display it anyway.
When a SSID is “hidden” and a wireless client cannot see it, the only way you can connect to
the SSID is by manually entering the SSID name in your wireless connection setup screen(s)
(these vary by client, client connectivity software, and operating system).
