Infrastructure Wireless Repeater

The access point can also operate in a bridge “repeater” mode to extend the range 
of links to wireless clients. The access point uses WDS to forward traffic between 
the repeater bridge and the root bridge. The access point supports up to six WDS 
repeater links.

In repeater mode, the access point does not support an Ethernet link to a wired LAN. 
Note that when the access point operates in this mode only half the normal 
throughput is possible. This is because the access point has to receive and then 
re-transmit all data on the same channel.
