[1-32
characters]
to enable this function.
BSSID
The BSSID is a 48-bit identity used to identify a particular BSS
(Basic Service Set) within an area. In Infrastructure BSS
networks, the BSSID is the MAC (Media Access Control) address of
the AP (Access Point); and in Independent BSS or ad hoc networks,
the BSSID is generated randomly.
Max Clients
The maximum number of clients that can access the router.
Wireless Guest /
Virtual
Access Points
This router supports multiple SSIDs called Guest SSIDs or Virtual
Access Points. To enable one or more Guest SSIDs select the
checkboxes
in the Enabled column. To hide a Guest SSID select
its checkbox
in the Hidden column.
Do the same for Isolate Clients and Disable WMM Advertise.
For a description of these two functions, see the previous entries for
“Clients Isolation” and “Disable WMM Advertise”. Similarly, for
Enable WMF, Max Clients and BSSID, consult the matching
entries in this table.
NOTE: Remote wireless hosts cannot scan Guest SSIDs.
111
6.2 Security
The following screen appears when Wireless Security is selected. The options shown
here allow you to configure security features of the wireless LAN interface.
Click Save/Apply to implement new configuration settings.
WIRELESS SECURITY
Wireless security settings can be configured according to Wi-Fi Protected Setup
(WPS) or Manual Setup. The WPS method configures security settings automatically
(see
112
6.2.1 WPS) while the Manual Setup method requires that the user configure these
settings using the Web User Interface (see the table below).
Select SSID
Select the wireless network name from the drop-down box. SSID stands for Service
Set Identifier. All stations must be configured with the correct SSID to access the
WLAN. If the SSID does not match, that client will not be granted access.
Network Authentication
This option specifies whether a network key is used for authentication to the
wireless network. If network authentication is set to Open, then no authentication
is provided. Despite this, the identity of the client is still verified.
Each authentication type has its own settings. For example, selecting 802.1X
authentication will reveal the RADIUS Server IP address, Port and Key fields. WEP
Encryption will also be enabled as shown below.
The settings for WPA authentication are shown below.
113
The settings for WPA-PSK authentication are shown next.
WEP Encryption
This option specifies whether data sent over the network is encrypted. The same
network key is used for data encryption and network authentication. Four network
keys can be defined although only one can be used at any one time. Use the Current
Network Key list box to select the appropriate network key.
Security options include authentication and encryption services based on the wired
equivalent privacy (WEP) algorithm. WEP is a set of security services used to
protect 802.11 networks from unauthorized access, such as eavesdropping; in this
case, the capture of wireless network traffic. When data encryption is enabled,
secret shared encryption keys are generated and used by the source station and the
destination station to alter frame bits, thus avoiding disclosure to eavesdroppers.
Under shared key authentication, each wireless station is assumed to have received
a secret shared key over a secure channel that is independent from the 802.11
wireless network communications channel.
Encryption Strength
This drop-down list box will display when WEP Encryption is enabled. The key
strength is proportional to the number of binary bits comprising the key. This
means that keys with a greater number of bits have a greater degree of security and
are considerably more difficult to crack. Encryption strength can be set to either
64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10
hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26
hexadecimal numbers. Each key contains a 24-bit header (an initiation vector)
which enables parallel decoding of multiple streams of encrypted data.
114
6.2.1 WPS
Wi-Fi Protected Setup (WPS) is an industry standard that simplifies wireless security
setup for certified network devices. Every WPS certified device has a PIN number
accessed through device software. The AR-5381u has a virtual button accessible
from the web user interface (WUI).
Devices with the WPS logo (shown here)
support WPS. If the WPS logo is not present
on your device it still may support WPS, in
this case, check the device documentation
for the phrase “Wi-Fi Protected Setup”.
NOTE:
WPS is only available in Open, WPA-PSK, WPA2-PSK and Mixed
WPA2/WPA-PSK network authentication modes. Other authentication
modes do not use WPS so they must be configured manually.
To configure security settings with WPS, follow the procedures below. You must
choose either the Push-Button or PIN configuration method for Steps 6 and 7.
I. Setup
Step 1:
Enable WPS by selecting Enabled from the drop down list box shown.
Step 2:
Set the WPS AP Mode. Configured is used when the AR-5381u will assign
security settings to clients. Unconfigured is used when an external
client assigns security settings to the AR-5381u.
NOTES:
Your client may or may not have the ability to provide security settings to
the AR-5381u. If it does not, then you must set the WPS AP mode to
Configured. Consult the device documentation to check its capabilities.
In addition, using Windows Vista, you can add an external registrar using
the StartAddER button (Appendix D - WPS OPERATION) has detailed
instructions).
115
II. NETWORK AUTHENTICATION
Step 3: Select Open, WPA-PSK, WPA2-PSK, or Mixed WPA2/WPA-PSK network
authentication mode from the Manual Setup AP section of the Wireless
Security screen. The example below shows WPA2-PSK mode.
Step 4:
For the Pre-Shared Key (PSK) modes, enter a WPA Pre-Shared Key. You
will see the following dialog box if the Key is too short or too long.
Step 5:
Click the Save/Apply button at the bottom of the screen.
IIIa. PUSH-BUTTON CONFIGURATION
The WPS push-button configuration provides a semi-automated configuration
method. The WPS button on the rear panel of the router can be used for this
purpose or the Web User Interface (WUI) can be used exclusively.
The WPS push-button configuration is described in the procedure below. It is
assumed that the Wireless function is Enabled and that the router is configured as
the Wireless Access Point (AP) of your WLAN. In addition, the wireless client must
also be configured correctly and turned on, with WPS function enabled.
116
NOTE:
The wireless AP on the router searches for 2 minutes. If the router stops
searching before you complete Step 7, return to Step 6.
Step 6: Press WPS button
Press the WPS button on the front panel of the router. The WPS LED will
blink to show that the router has begun searching for the client.
Step 7:
Go to your WPS wireless client and activate the push-button function.
A typical WPS client screenshot is shown below as an example.
Now go to Step 8 (part IV. Check Connection) to check the WPS connection.
IIIb. WPS – PIN CONFIGURATION
Using this method, security settings are configured with a personal identification
number (PIN). The PIN can be found on the device itself or within the software.
The PIN may be generated randomly in the latter case. To obtain a PIN number for
your client, check the device documentation for specific instructions.
The WPS PIN configuration is described in the procedure below. It is assumed that
the Wireless function is Enabled and that the router is configured as the Wireless
Access Point (AP) of your wireless LAN. In addition, the wireless client must also be
configured correctly and turned on, with WPS function enabled.
NOTE:
Unlike the push-button method, the pin method has no set time limit.
This means that the router will continue searching until it finds a client.
Step 6:
Select the PIN radio button in the WSC Setup section of the Wireless
Security screen, as shown in A or B below, and then click the appropriate
button based on the WSC AP mode selected in step 2.
A - For Configured mode, click the Add Enrollee button.
Enter STA PIN: a Personal Identification Number (PIN) has to be read from either
a sticker or the display on the new wireless device. This PIN must then be inputted
at representing the network, usually the Access Point of the network.
B - For Unconfigured mode, click the Config AP button.
117
Step 7:
Activate the PIN function on the wireless client. For Configured mode,
the client must be configured as an Enrollee. For Unconfigured mode,
the client must be configured as the Registrar. This is different from the
External Registrar function provided in Windows Vista.
The figure below provides an example of a WPS client PIN function in-progress.
Now go to Step 8 (part IV. Check Connection) to check the WPS connection.
IV. CHECK CONNECTION
Step 8:
If the WPS setup method was successful, you will be able access the
wireless AP from the client. The client software should show the status.
The example below shows that the connection established successfully.
You can also double-click the Wireless Network Connection icon from the
Network Connections window (or the system tray) to confirm the status of
the new connection.

but drops to lower rates when necessary. 1 Mbps, 2Mbps,
5.5Mbps, or 11Mbps fixed rates. The appropriate setting
is dependent on signal strength.
Multicast Rate
Setting for multicast packet transmit rate (1-54 Mbps)
Basic Rate
Setting for basic transmission rate.
123
Field
Description
Fragmentation
Threshold
A threshold, specified in bytes, that determines whether
packets will be fragmented and at what size. On an
802.11 WLAN, packets that exceed the fragmentation
threshold are fragmented, i.e., split into, smaller units
suitable for the circuit size. Packets smaller than the
specified fragmentation threshold value are not
fragmented. Enter a value between 256 and 2346. If you
experience a high packet error rate, try to slightly increase
your Fragmentation Threshold. The value should remain
at its default setting of 2346. Setting the Fragmentation
Threshold too low may result in poor performance.
RTS Threshold
Request to Send, when set in bytes, specifies the packet
size beyond which the WLAN Card invokes its RTS/CTS
mechanism. Packets that exceed the specified RTS
threshold trigger the RTS/CTS mechanism. The NIC
transmits smaller packet without using RTS/CTS. The
default setting of 2347 (maximum length) disables RTS
Threshold.
DTIM Interval
Delivery Traffic Indication Message (DTIM) is also known
as Beacon Rate. The entry range is a value between 1
and 65535. A DTIM is a countdown variable that informs
clients of the next window for listening to broadcast and
multicast messages. When the AP has buffered
broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. AP
Clients hear the beacons and awaken to receive the
broadcast and multicast messages. The default is 1.
Beacon Interval
The amount of time between beacon transmissions in
milliseconds. The default is 100 ms and the acceptable
range is 1 – 65535. The beacon transmissions identify
the presence of an access point. By default, network
devices passively scan all RF channels listening for
beacons coming from access points. Before a station
enters power save mode, the station needs the beacon
interval to know when to wake up to receive the beacon
(and learn whether there are buffered frames at the
access point).
Global Max Clients
The maximum number of clients that can connect to the
router.
Xpress
TM
Technology
Xpress Technology is compliant with draft specifications of
two planned wireless industry standards.
Transmit Power

WMM No
Acknowledgement
Refers to the acknowledge policy used at the MAC level.
Enabling no Acknowledgement can result in more efficient
throughput but higher error rates in a noisy Radio
Frequency (RF) environment.

Appendix A - Firewall
STATEFUL PACKET INSPECTION
Refers to an architecture, where the firewall keeps track of packets on each
connection traversing all its interfaces and makes sure they are valid. This is in
contrast to static packet filtering which only examines a packet based on the
information in the packet header.
DENIAL OF SERVICE ATTACK
Is an incident in which a user or organization is deprived of the services of a
resource they would normally expect to have. Various DoS attacks the device can
withstand are ARP Attack, Ping Attack, Ping of Death, Land, SYN Attack, Smurf
Attack, and Tear Drop.
TCP/IP/PORT/INTERFACE FILTER
These rules help in the filtering of traffic at the Network layer (i.e. Layer 3).
When a Routing interface is created, Enable Firewall must be checked.
Navigate to Advanced Setup
Security
IP Filtering.
OUTGOING IP FILTER
Helps in setting rules to DROP packets from the LAN interface. By default, if the
Firewall is Enabled, all IP traffic from the LAN is allowed. By setting up one or more
filters, specific packet types coming from the LAN can be dropped.

dependent on the particular requirements of the ISP. The user name can be a
maximum of 256 characters and the password a maximum of 32 characters in
length. For Authentication Method, choose from AUTO, PAP, CHAP, and MSCHAP.
ENABLE FULLCONE NAT
This option becomes available when NAT is enabled. Known as one-to-one NAT, all
requests from the same internal IP address and port are mapped to the same
external IP address and port. An external host can send a packet to the internal host,
by sending a packet to the mapped external address.
DIAL ON DEMAND
The AR5381U can be configured to disconnect if there is no activity for a period of
time by selecting the Dial on demand checkbox . You must also enter an
inactivity timeout period in the range of 1 to 4320 minutes.
PPP IP EXTENSION
The PPP IP Extension is a special feature deployed by some service providers.
Unless your service provider specifically requires this setup, do not select it.
PPP IP Extension does the following:
•
•
•
•
•
•
Allows only one PC on the LAN.
Disables NAT and Firewall.
The device becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
The device extends the IP subnet at the remote service provider to the
LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.
The device bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the device’s LAN IP address.
The public IP address assigned by the remote side using the PPP/IPCP
protocol is actually not used on the WAN PPP interface. Instead, it is
forwarded to the PC LAN interface through DHCP. Only one PC on the
LAN can be connected to the remote, since the DHCP server within the
device has only a single IP address to assign to a LAN device.
ENABLE NAT
If the LAN is configured with a private IP address, the user should select this
checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot.
On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN
side is using a public IP), this checkbox
should not be selected to free up system
resources for better performance.
ENABLE FIREWALL
If this checkbox
is selected, the Security submenu will be displayed on the
Advanced Setup menu after reboot. If firewall is not necessary, this checkbox
should not be selected to free up system resources for better performance.
166
USE STATIC IPv4 ADDRESS
Unless your service provider specially requires it, do not select this checkbox . If
selected, enter the static IP address in the IPv4 Address field.
Don’t forget to adjust the IP configuration to Static IP Mode as described in Section
3.2
MTU
Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which
the layer can pass onwards. This value is 1500 for PPPoA.
ENABLE PPP DEBUG MODE
When this option is selected, the system will put more PPP connection information
into the system log. This is for debugging errors and not for normal usage.
ENABLE IGMP MULTICAST PROXY
Tick the checkbox
to enable Internet Group Membership Protocol (IGMP)
multicast. This protocol is used by IPv4 hosts to report their multicast group
memberships to any neighboring multicast routers.
NO MULTICAST VLAN FILTER
Tick the checkbox
to Enable/Disable multicast VLAN filter.
Enable WAN interface with base MAC
Enable this option to use the router’s base MAC address as the MAC address for this
WAN interface.
STEP 3: Choose an interface to be the default gateway.
Click Next to continue or click Back to return to the previous step.
167
Select DNS Server Interface from available WAN interfaces OR enter static DNS
server IP addresses for the system. In ATM mode, if only a single PVC with IPoA or
static IPoE protocol is configured, Static DNS server IP addresses must be entered.
Click Next to continue or click Back to return to the previous step.
STEP 5: The WAN Setup - Summary screen shows a preview of the WAN service
you have configured. Check these settings and click Apply/Save if they
are correct, or click Back to modify them.
168
After clicking Apply/Save, the new service should appear on the main screen.

The PPP username and password are dependent on the requirements of the ISP.
The user name can be a maximum of 256 characters and the password a maximum
of 32 characters in length. (Authentication Method: AUTO, PAP, CHAP, or MSCHAP.)
ENABLE FULLCONE NAT
This option becomes available when NAT is enabled. Known as one-to-one NAT, all
requests from the same internal IP address and port are mapped to the same
external IP address and port. An external host can send a packet to the internal host,
by sending a packet to the mapped external address.
179
DIAL ON DEMAND
The AR5381U can be configured to disconnect if there is no activity for a period of
time by selecting the Dial on demand checkbox . You must also enter an
inactivity timeout period in the range of 1 to 4320 minutes.
PPP IP EXTENSION
The PPP IP Extension is a special feature deployed by some service providers.
Unless your service provider specifically requires this setup, do not select it.
PPP IP Extension does the following:
•
•
•
•
•
•
Allows only one PC on the LAN.
Disables NAT and Firewall.
The device becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
The device extends the IP subnet at the remote service provider to the
LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.
The device bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the device’s LAN IP address.
The public IP address assigned by the remote side using the PPP/IPCP
protocol is actually not used on the WAN PPP interface. Instead, it is
forwarded to the PC LAN interface through DHCP. Only one PC on the
LAN can be connected to the remote, since the DHCP server within the
device has only a single IP address to assign to a LAN device.
ENABLE NAT
If the LAN is configured with a private IP address, the user should select this
checkbox . The NAT submenu will appear in the Advanced Setup menu after reboot.
On the other hand, if a private IP address is not used on the LAN side (i.e. the LAN
side is using a public IP), this checkbox
should not be selected to free up system
resources for better performance.
ENABLE FIREWALL
If this checkbox
is selected, the Security submenu will be displayed on the
Advanced Setup menu after reboot. If firewall is not necessary, this checkbox
should not be selected to free up system resources for better performance.
USE STATIC IPv4 ADDRESS
Unless your service provider specially requires it, do not select this checkbox . If
selected, enter the static IP address in the IP Address field. Also, don’t forget to
adjust the IP configuration to Static IP Mode as described in Section 3.2.
Fixed MTU
Maximum Transmission Unit. The size (in bytes) of largest protocol data unit which
the layer can pass onwards. This value is 1500 for PPPoA.
ENABLE PPP DEBUG MODE
When this option is selected, the system will put more PPP connection information
into the system log. This is for debugging errors and not for normal usage.
180
