Symptoms:
When I turn on my wireless bridge, the WLAN light flashes normally, indicating that it's picking up the router which is in the next room
When I plug an ethernet cable into it, the WLAN light STOPS flashing and my computer gets "limited or no connectivity"
When I turn it on with an ethernet cable plugged in, WLAN blinks a few times and stops
Note: I'm currently using my much-slower USB adapter to connect to my router, so it's not a problem with the wireless network. Also, my bridge worked perfectly for weeks and I just now got this problem
