I have a TivoHD that is up and running just fine. The wired ethernet works fine, but I don't like running the ethernet cable along my ceiling, so I bought the official Tivo Wireless G USB Network Adapter since I already have a wireless network set up. It seems to work fine with no encryption, but I can't get the thing to work at all with WEP encryption. I haven't yet tried WPA, but I can once I figure out how to enable it on my linux box. Has anyone successfully gotten the Tivo Wireless Adapter to work on the TivoHD with WEP encryption? I've tried inputting the password as plain text and in hexidecimal mode (by switching modes with the INFO button) and neither seem to work. I've also tried rebooting the Tivo, unplugging and replugging in the adapter, even changing passwords on the router. And the WEP password works fine on my macbook and linux box, so I know I have the password correct. I finally only got it to work by temporarily turning off encryption, but that's not a long term solution for me. And by the way, I know that WEP isn't as secure as WPA, so I don't need to hear that. Like I said I'm willing to try WPA if others report that that works fine with my setup, I just haven't bothered upgrading to it yet. I'd love to go through the Tivo online support to find help on this issue, but their customer support site has been down since at least last night. Thanks for any help you can provide.
