I have been running my Tivo for over a year with a Linksys WRT54G Router and a D-Link Wireless B Adapter (Model No. DWL-122) without any issues. I wanted to upgrade to a faster wireless G adapter so I just purchased a new Tivo Wireless G USB Adapter (Model No. AG0100). I disconnected my D-Link and connected my new Tivo Wireless G USB Adapter and didn't receive a message stating that if found a new network adapter. On the main 'Phone & Network' screen under 'Network Connection Details' is says 'No Connection'. I tried selecting 'Use Network Instead' then 'Yes, I have all of the above' then 'OK, I've plugged in a Network Adapter' and then I get a screen stating 'Ethernet Not Found The Tivo DVR has not detected an Ethernet link. I tried restarting the tivo from the menu option with no luck. I have tried unplugging the tivo and plugging it back in with the Adapter Plugged in and no success. I have also tried restarting/unplugging the tivo with no adapter unplugged and then plugged it in afterward and still no success. I am currently running Tivo Software Version 7.3.1-oth-01-2-540 I even swapped out my first Tivo Wireless Adapter and got a whole new Tivo Wireless Adapter (usb wire and all) and still have the same problem. I can't figure out why a Tivo Wireless Adapter made by Tivo for Tivo doesn't just work without any issues? Does anyone think it is because of the Software Version 7.3.1-oth-01-2-540 that I am running or maybe because the Tivo still some how is getting the D-Link Adapter confused with the Tivo Adapter and doesn't want to install or recognize the Tivo Adapter?? PLEASE HELP!!!! As a last resort I did a full Reset and Clear of my Tivo to start from Scratch. Oh yeah, I tried 2nd USB Port as well. Any suggestions!!!!!
