TiVo AG0100 Wireless G USB Network Adapter for TiVo Series 2 and Series 3 DVRs
The one to get for a TIVO
Before I decided to go wireless, I had 5 TIVOs (yeah, 5-- everyone in the house has one). They were wired together via a 100Mbs switch and also connected to the Internet via cable modem for updates.  I replaced my old 8-year old UMAX router with a new Linksys WRT54GX4 wireless-G MIMO router.  It also had 4 wired ports, which I tried first, and they worked OK. <br /> <br />The problem was that a few of the wired TIVOs took forever to transfer programs to another TIVO for viewing, even after I swapped out to the new router.  If I started a transfer from those TIVOs, and then started to view it on the receiving TIVO, I would often have to wait for the receiving TIVO to get more, as the playback was way faster than the transfer. <br /> <br />So I replaced the wired connection to one of the problem TIVOs with this TIVO certified wireless solution.  Now I can transfer a 30-minute program in 8 minutes.  And this is from the TIVO that is 60 feet away, behind 4 walls.  Signal strength is between 68% and 75%, which is outstanding for the distance and obstacles.   <br /> <br />I highly recommend this solution for your TIVOs, if you do not have a wired solution and don't feel like pulling cable through your house.  Yes, it is a bit costly, but at least you will not be punching holes in your walls.  It should also be backward compatible with wireless-B routers, but I cannot vouch for that.  Also, it supports WEP encryption, but not WPA or WPA2, so that might be a security drawback if you have a high level of paranoia. <br /> <br />Setup on the TIVO is automatic; once you plug it in, the Series 2 TIVO will automatically recognize it.  Configuring it might be a wee bit of a problem; so you should read a few FAQs on wireless networking if you don't know what you are doing.  I didn't know that much about wireless, but it only took me a few minutes to figure out.  Your milage may vary.  Heck, if you have a wireless router, you are probably smart enough now to get it working in no time.
