I have a LinkSys and it works fine with LM8.1... to get more info as to what might be happening with the router, upgrade its software to one that has logging capabilities (I'm running 1.40.1) and set it up to log the connection attempts; you don't actually need a logging server to see what the router might be rejecting (see my web page at http://pfortin.com/Linux/LinkSys/), just watch what the router is sending... these logging packets are "send and pray" in that they are sent only once each and do not expect a response. Take a trace of the working traffic with ethereal and tcpdump; then again with the router inline and watch for unexpected log entries. HTH, Pierre
