I bought a used TiVo Series2 TDC540040 (40 GB) Receiver with lifetime ( I called into Tivo and they told me it has lifetime.) I don't have a phone line anymore, so I tried to connect it to my wireless network. I have currently 3 Tivos connected and have never had a problem with the network. When I received the Tivo it was in the set up mode. It was asking the zip code and all of that. I gave it my wireless network password and it always comes back with error N-O2. I used all the default setting when setting up the wireless. So then I thought 'I will try something else' and set it up for the Tivo to give the IP address and it seemed to accept that. But when I tried to connect to Tivo it said 'No DHCP server'. I used known good wireless Tivo adapters and used different ones, and moved the Tivo to right next to the wireless transmitter when it wouldn't work right. I guess I could take it to a friends house and try their phone line or change out the hard drive. Any other options?
