TiVo AG0100 Wireless G USB Network Adapter for TiVo Series 2 and Series 3 DVRs
TiVo Wireless G  USB adapter fits the bill for TiVo DVR
If you're looking for a USB network adapter to use with a TiVo series 2 DVR, then the TiVo Wireless G USB network adapter fits the bill just fine. I have to say that overall I'm very disappointed with TiVo series 2 DVR's compatibility with USB network adapters. There are many good 802.11g USB network adapters available on the market at affordable prices, but you'll find the TiVo series 2 DVR is not compatible with most of them. I really think TiVO should update the network technology of their box. They're way behind. I settled on the TiVo Wireless G USB network adapter because it was one of the few that works perfectly with my TiVo, but it does not support security features that I really wish it did support. For example the only wireless security it supports is WEP encryption. It does not support WPA at all. And by the way, if you decide to use WEP encryption, make sure you use a Hex key, not an ASCII key. When I tried to set it up using a 128-bit ASCII key it would not connect to the wireless network at all. As soon as I changed to a Hex key, it finally connected and has maintained a reliable connection ever since.<br /><br />If you're looking for a USB network adapter that will work reliably with the TiVo series 2 DVR, this is a good one to consider.
