Since I've gotten my Roamio Plus I have gotten intermittent networking issue where an error displays on the Tivo central screen giving a C133 error. I have not had a chance to look into it much until today, but when it happened again I tried to force a connection which failed with N11 and N14 errors. I called Tivo and they had me try a couple of things, including rebooting the box. Nothing worked but the error did disappear while on the phone. The man I spoke to said this is actually a known issue that they are working on and issued me a case number. If anyone else has this problem I encourage you to call as well.
