6.7  Interface  Grouping 
Interface Grouping supports multiple ports to PVC and bridging groups. Each group performs as 
an independent network. To use this feature, you must create mapping groups with appropriate 
LAN and WAN interfaces using the Add button.   
The Remove button removes mapping groups, returning the ungrouped interfaces to the Default 
group. Only the default group has an IP interface. 
To add an Interface Group, click the Add button. The following screen will appear.    It lists the 
available and grouped interfaces. Follow the instructions shown onscreen. 

97 
Automatically Add Clients With Following DHCP Vendor IDs: 
Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID (option 60). The 
local DHCP server will decline and send the requests to a remote DHCP server by mapping the 
appropriate LAN interface. This will be turned on when Interface Grouping is enabled. 
For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/VCI=0/33 is for PPPoE while 
the other PVCs are for IP set-top box (video). The LAN interfaces are ETH1, ETH2, ETH3, and 
ETH4. 

98 
The Interface Grouping configuration will be: 
1. Default: ETH1, ETH2, ETH3, and ETH4. 
2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor ID is "Video". 
If the onboard DHCP server is running on "Default" and the remote DHCP server is running on PVC 
0/36 (i.e. for set-top box use only). LAN side clients can get IP addresses from the CPE's DHCP 
server and access the Internet via PPPoE (0/33). 
If a set-top box is connected to ETH1 and sends a DHCP request with vendor ID "Video", the local 
DHCP server will forward this request to the remote DHCP server. The Interface Grouping 
configuration will automatically change to the following: 
1. Default: ETH2, ETH3, and ETH4 
2. Video: nas_0_36, nas_0_37, nas_0_38, and ETH1

functionality, which provides basic quality of service for time-sensitive 
applications (e.g. VoIP, Video). 
Enable Wireless 
Multicast 
Forwarding 
Select the checkbox  to enable this function. 
Enable WiFi 
Button 
Select the checkbox  to enable the WiFi button. 
SSID 
[1-32 
characters] 
Sets the wireless network name. 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 user will not be granted access.     
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. 
Country 
Local regulations limit channel range: US/Canada = 1-11. 
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

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. 

110 
6.12.2 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 Apply/Save to implement new configuration settings. 
WIRELESS SECURITY 
Setup 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. 

111 
The settings for WPA authentication are shown below. 
The settings for WPA-PSK authentication are shown next. 

112 
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. 

113 
6.12.3 WPS 
Wi-Fi Protected Setup (WPS) is an industry standard that simplifies wireless security setup for 
certified network devices. Every WPS certified device has both a PIN number and a push button, 
located on the device or accessed through device software. The AR-5313u has a WPS button on 
the device. 
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.   
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-5313u will assign security 
settings to clients. Unconfigured is used when an external client assigns security 
settings to the AR-5313u. 
NOTES:  Your client may or may not have the ability to provide security settings to the 
AR-5313u. If it does not, then you must set the WPS AP mode to Configured. Consult 
the device documentation to check its capabilities.

IIa.    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. 
NOTE:  The wireless AP on the router searches for 2 minutes.    If the router stops searching 
before you complete Step 4, return to Step 3. 
Step 3:   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 4:  Go to your WPS wireless client and activate the push-button function.     
  A typical WPS client screenshot is shown below as an example. 
IIb.    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 5:  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. 

115 
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. 
Step 6:  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. 
III. CHECK CONNECTION 
Step 7:  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.

The new amendment allows IEEE 802.11n units to fall back to 
slower speeds so that legacy IEEE 802.11x devices can coexist 
in the same network. IEEE 802.11g creates data-rate parity at 
2.4 GHz with the IEEE 802.11a standard, which has a 54 Mbps 
rate at 5 GHz. (IEEE 802.11a has other differences compared to 
IEEE 802.11b or g, such as offering more channels.) 
Channel 
Drop-down menu that allows selection of a specific channel. 
Auto Channel Timer

RIFS Advertisement 
One of several draft-n features designed to improve efficiency. 
Provides a shorter delay between OFDM transmissions than 
in802.11a or g. 
OBSS Co-Existence 
Co-existence between 20 MHZ AND 40 MHZ overlapping Basic 
Service Set (OBSS) in WLAN. 
RX Chain Power Save 
Enabling this feature turns off one of the Receive chains, going 
from 2x2 to 2x1 to save power. 
RX Chain Power Save 
Quiet Time 
The number of seconds the traffic must be below the PPS value 
below before the Rx Chain Power Save feature activates itself. 
RX Chain Power Save 
PPS

processed by the WLAN interface for a duration of Quiet Time, 
described above, before the Rx Chain Power Save feature 
activates itself. 
54g Rate 
Drop-down menu that specifies the following fixed rates:    Auto: 
Default.    Uses the 11 Mbps data rate when possible 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. 

121 
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 
Set the power output (by percentage) as desired. 
WMM (Wi-Fi 
Multimedia) 
The technology maintains the priority of audio, video and voice 
applications in a Wi-Fi network. It allows multimedia service get 
higher priority. 
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. 
WMM APSD 
This is Automatic Power Save Delivery. It saves power.
