Is anyone having problems connecting their Roamio via Wifi? I'm using the current (6th Generation) Apple Airport Extreme router. After a lot of fooling around, the only way I was able to connect via Wifi was to: 1. Turn off MAC filtering (called Timed Access Control in Apple's Airport Utility). I'm certain I typed the MAC address correctly as shown on the Tivo screen, and I have 9 other devices that connect with no problems. 2. Plug in a hardwired Ethernet cable first, before choosing "Connect Using Wireless." It doesn't make any sense to have to do this for a wireless setup. Even after doing this, the "Network Connection" screen doesn't refresh to show a wireless connection. You have to go to the "Network Diagnostics" screen and come back to it. If I undo either of those two steps and try connecting again via wireless, I get a "Wireless Network Problem" screen, error code (N06). There are some troubleshooting tips on that screen, and then it says "For more info, visit tiro.com/help/N06," which brings you to a web page that says "Internal Server Error." I called up Tivo Support, and the representative didn't know about this issue and wasn't very helpful.
