Need to reset old N adapter using PC.

I recently switched my cable company and decided to try their DVR. I wasn't happy, so I switched back to TiVO. The problem is I changed my network name and password. I need to reset my N adapter, but I have an old model that doesn't have the reset button (or the Client/Bridge switch). I think there's a way to do it on my PC, but I cannot find the place to do it. Can anyone point me to the right place? It's getting me crazy because I know I've changed the password before.

I even tried resetting my network name back to the original, but it didn't work.

 

Thanks. I talked with someone at support and we got it figured out.
