Unreliable service
I've been experiencing frequent TV outages where the sound on TV goes out or picture just goes black. This requires a restart of the cable box and sometimes even the internet modem. Sometimes after the restart the problem persists. When changing channels through the guide or with the channel button, the TV lags considerably.
Internet also seems to lag periodically, cutting out in the middle of the day, which makes working from home an ordeal.
This is after the first TV box and internet modem I got just plain did not work. The second set lagged so badly in both internet and TV it was practically unusable. So this is set number 3, which I guess you could say "works" but is still not quite right.
I have never experienced such unreliable service from any other internet/TV provider. It's really ridiculous that they charge so much for such awful service.
