Tried the X - II (cross over or straight through) switch. The interesting thing is that on straight through the link light on the Rio goes out, but on cross over the Rio link light is on. In both cases the bridge link light is off.
The bridge does function; if I take a computer off the router and plug it into the bridge, the bridge link light comes on (as does the NIC link light on the computer) and I can access the network and internet on that computer connected through the bridge.
I'm really at wits end; bridge works, Rio works (when connected via ethernet cable to router) and bridge is supposed to make ANY etherner device work wirelessly but they don't want to work. Grrrrrrrr...
