Hi, have my Roamio Pro for about a week now.
Ever since getting it, I've had problems with internet connectivity.
When I press the TiVO button, or when I go to the what to watch now section, I'd see various messages about not connected to the internet , or not connected to the tivo service, or connected to the internet but some problem. Netflix also fails to connect.
Errors: C501, C133, ui-133
When the problem happens, I just need to wait a couple of seconds, then it resolves itself and the error goes away.
If the error shows up, and I troubleshoot the network connection, it always works, no problems.
My iOS TiVO apps also report the box has lost internet connectivity.
It looks like the TiVo has some intermittent network problem.
I contacted chat support, and I felt like the person could not get me of the line quick enough, did you reboot, no, have you rebooted, no, ok reboot, and then come back, bye.
I've swapped ethernet cables.
I've swapped switch ports.
My internet connection is working just fine.
I have many devices connected and none have any problems.
I tried the same CAT6 cable that my working Roku uses for the TiVO, same problem.
Searching I see old threads dating back to 2011 with similar symptoms.
Wired CAT6 ethernet.
