4.5 WMM
Setup > Wireless Settings > WMM
Wi-Fi Multimedia (WMM) provides basic Quality of service (QoS) features to IEEE
802.11 networks. WMM prioritizes traffic according to four Access Categories (AC) -
voice, video, best effort, and background .

Wireless distribution system (WDS)
Setup > Wireless Settings > WDS
Wireless distribution system is a system enabling the wireless interconnection of
access points in a network. This feature is only guaranteed to work only between
devices of the same type.
Figure 49: Wire le ss Distribution Syste m
This feature is only guaranteed to work only between devices of the same type (i.e.
using the same chipset/driver). For example between two DSR250N boxes, or
between two DSR1000N. It should also interoperate between a DSR 1000N and
DSR 500 N boxes since they are based on the same chipset/driver.
When the user enables the WDS links use the same security configuration as the
default access point. The WDS links do not have true WPA/WPA2 s upport, as in there
is no WPA key handshake performed. Instead the Session Key to be used with a WDS
Peer is computed using a hashing function (similar to the one used for computing a
WPA PMK). The inputs to this function are a PSK (configurable by an administrator
from the WDS page) and an internal "magic" string (non -configurable).
In effect the WDS links use TKIP/AES encryption, depending on the encryption
configured for the default AP. In case the default AP use s mixed encryption (TKIP +
AES).The WDS link will use the AES encryption scheme.

For a WDS link to function properly the Radio settings on the WDS peers have to
be the same.
The WDS page would consist of two sections. The first section provides general WDS
settings shared by all its WDS peers.
WDS Enable
- This would be a check box
WDS Encryption - Displays the type of encryption used. It could be one of OPEN/64
bit WEP/128 bit WEP/TKIP/AES (Use the term being used throughout the box i.e.
either CCMP or AES).
WDS Passphrase
- This is required if the encryption selected is TKIP/CCMP. We
would expect it to be within 8~63 ASCII characters. In the WDS configuration page
this field is mandatory and has to be same on the two WDS peers, when the security is
configured in TKIP/AES mode. The WDS links use th is as the PSK for the
connection.
DUT's Mac Address
- This would be the mac address of this box. This should be
configured in the peer's WDS configuration page to be able to establish a WDS link
with this box. This field in the WDS Configuration section displays the device's mac
address, which needs to be specified on the WDS peer for making a connection to this
device (Similarly the WDS peers MAC address will have to be specified on this
device for the WDS link to be established between the two devices).
The second section will have the list of configured WDS peers with buttons to
Add/Delete Peer entries. We support up to a maximum of 4 WDS links per box.
The both devices need to have same wireless settings (wireless mode, encryption,
authentication method, WDS passphrase, WDS MAC address and wireless SSID)
when we configure WDS features in DSR router.
The "Add WDS Peer" section allows the user to specify a WDS peer. The "WDS
Peers" table displays the list of WDS peers currently configured on the device. A
maximum of 4 WDS peers can be specified in any given mode.

Advanced Wireless Settings
Advanced > Wireless Settings > Advanced Wireless
Sophisticated wireless administrators can modify the 802.11 communication
parameters in this page. Generally, the default settings are appropriate for most
networks. Please refer to the GUI integrated help text for further details on the use of
each configuration parameter.

Wi-Fi Protected Setup (WPS)
Advanced > Wireless Settings > WPS
WPS is a simplified method to add supporting wireless clients to the network. WPS is
only applicable for APs that employ WPA or WPA2 security. To use WPS, select the
eligible VAPs from the dropdown list of APs that h ave been configured with this
security and enable WPS status for this AP.
The WPS Current Status section outlines the security, authentication, and encryption
settings of the selected AP.
These are consistent with the AP’s profile.
There are two
setup options available for :
Personal Identification Number (PIN):
The wireless device that supports WPS
may have an alphanumeric PIN, if so add the PIN in this field. The router will
connect within 60 seconds of clicking the “Configure via
PIN” button immediately
below the PIN field. There is no LED indication that a client has connected.
Push Button Configuration (PBC):
for wireless devices that support PBC, press
and hold down on this button and within 2 minutes click the PBC connect butt on.
The AP will detect the wireless device and establish a link to the client.

More than one AP can use WPS, but only one AP can be used to establish WPS
links to client at any given time.
