Go to Wireless | Basic Settings to change the Wireless Bridge mode from
Infrastructure to Adhoc, or you can also change the SSID, Channel, Transmission
Rate and Wireless Mode.
Note that when configured as a Wireless Bridge, changing the channel of the
SMC2870W has no effect because it must connect to the network using the same
channel as your Access Point. If you wish to use a different channel, you must
change the channel in your Access Point’s configuration.
