Reset bridge to different router without the disk.

Follow these steps :
•1
Reset the bridge. Accomplish this by manually disconnecting the power source from the wall or the back of the bridge. Leave it disconnected for 30 seconds to a minute so that the software contained therein can fully reset. Reconnect the bridge and wait two to three minutes until the network is back up and running again. In many cases, a simple reset can solve your network-related bridge problems.
•2
Ascertain whether there is network activity on your computers. Accomplish this by looking at the back of each computer at the network card. There should be two lights next to your Ethernet port--at least one of these lights should be completely lit without flickering. This indicates that the network card in the machine is operational and ready to receive a signal, eliminating that as a possible problem source.
•3
Move the bridge to a different location to determine whether interference is preventing the network computers from receiving a proper signal. If possible, relocate the bridge to the same room in which the computers are located and try to reset the connection again.
•4
Determine whether the bridge has failed altogether or whether the wireless signal from the bridge has failed. Accomplish this by physically connecting the computers to the wireless bridge through the use of Ethernet cables. If this restores network connectivity, you know that the only problem with the bridge is the wireless signal emission.
