Same problem here too. It was fine, then I had buffering issues, then it wouldn't connect to the "internet"
It tells me I'm connected to the network, but not the "internet". I have done everything on the support site, and went to YouTube. I even went so far as getting a new modem and router. I haven't even had this tv for 2 years. I am appalled at the lack of support. I have emailed you and tried to chat. I have been a loyal customer of Roku before you even had Netflix as as channel. Come on... I think we all need some help.
