I have a new silver 540. It's connected to our 802.11b network and I can play music and view pictures from my PC. Every time I try to use the network to connect to Tivo for program data it says it Failed for Unknown Reason. I remembered to change the connection type from phone to network before trying to connect so that wasn't the problem. It works fine via phone for now. Anybody with a hint or suggestion? I have: Netgear MR814 v2 Netgear MA111 Bellsouth DSL with a Westell modem I'm using 128-bit WEP and not broadcasting the SSID and, as I said above, I am able to view content from my PC with no problems.
