I'm on a wireless network, have both my tivo boxes on it. It works great, I can access and change programing from my work computer and I can also access all my music and pictures on my computer thru TIVO on my TV. Plus lots of yahoo games and weather. Also can transfer programs between tivo boxes.

Good Luck

Hooking up to a network is way better than a phone line for the reasons already posted and more.

The Tivo only needs to "talk to the mothership" every 7 to 14 days to download the EPG.

When I set up my wireless Tivo's (I have 2 wireless, 1 wired), I needed a "real" phone line for the initial setup and system upgrade. Once the system was upgraded, the wireless adapters worked fine.

The last time I set up a Tivo was with a wired network adapter and it did not need a phone line for the initial setup.
