I am doing the initial set up on a resurrected SDH-400 with a 1 TB plug and go hard drive from Weaknees. While doing the set up, I can find my network on the list, but the TiVo will not connect to the network, I get "N06 - The wireless network was not found" I think the TiVo sees the network b/c its in the list. What exactly does this error mean?

Also, there is a network named "TiVo express" that just showed up on a recent reboot. i doubt it belongs to a neighbor. Can i use this network somehow instead of my home network? I tried to use it and got a fatal error with the instruction to reboot.
