I started to set up my shiny new Roamio Pro last night, getting the CableCard paired and channels working. Tonight, I called Tivo to purchase Lifetime service for the box. The real problems started tonight. When I tried to connect to the Tivo Service over Wi-Fi, which worked fine last night, I got a failure that it couldn't connect to the gateway. So I decided since I have a lot of stuff to transfer from my Series 3 1TB anyway, I'd just go wired. So I switched over and still couldn't connect to the Tivo Service. So I rebooted the Tivo as well as my switch and router. I finally connected to Tivo long enough for the box to determine it has Lifetime. But I got a failure a few moments after that. The network test passed, so I rebooted it again. After that reboot, it had the correct MAK. But it won't display shows from either my Tivo S3 or Tivo HD. It's also very hit-or-miss in showing the pytivo folder or my server folder. And I'm seeing C133 errors frequently. From my PC, I did 1000 pings to the wired port and lost 131 of those. I've swapped out the Ethernet cable and connected to a different port on the switch. I'm still getting dropped packets. Additionally, I've had the same failure to return from Standby on occasion. Thankfully, I had read the suggestion to use the power button on the face of the Roamio to turn it off (well, Standby) and back on. Another oddity is that somehow during the Tivo reboot, there is a brief period where the remote in RF mode emits a burst of IR that turns on *both* my other Tivos. (Must be using Remote Code 0). Finally, I've found that when I can navigate my pytivo folder, there is no way to move back UP the folder tree. One the Tivo S3, there is NO issue walking up and down the tree. Yet Roamio is missing this functionality? Yeesh. This is NOT smooth. I was willing to overlook things like the "UKNOWN" references on the menu. Maybe I just got a bad unit? It's crazy to have so many issues, right?
