 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 support, 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 uses 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
