I have a 540 series Tivo and have been struggled with getting two different wireless adapters to work with it. Finally, I went ahead and ordered Tivo's new Wireless G adapter last week. It arrived today, so I plug it into the USB port and get power (the power indicator lights up). Then nothing. The other light never flashes to indicate its trying to detect a network. When I go to 'setup' menu it doesn't detect a wireless network and won't let me adjust any settings. The support documents suggest this happens when using a wireless adapter that isn't supported. Obviously, Tivo's own wireless adapter should be supported. I've powercycled and unplugged and plugged everything about a dozen times. Any suggestions?
