Roku TCL tv connects to the arris tg862g routers WI-FI network but won't connect to the internet. I use MAC auth and its is all set up just fine, and gets the wifi connection, as well, but won't get the internet connection. I have exhausted the trouble shooting topics, all the resets reconfigs, reboots, power cut resets, tech support line helpers, etc, blah, blah.... So I thought well update the firmware. So... I can't get this stupid smart tv to authenticate a USB image of its firmware "software" update file, as per the roku web site firmware update authentication process. It will get to the last step to update the firmware then says "error". It is all making me think that TCL tv's just don't work - I have tried with 2 different models and get the same result. Maybe there is an issue with the wifi versions of my older router vs new tv? I have been trying to get a roku tv to save the money buying a streamer device - but 'bout to give up on roku tv's. ANYONE been through this mire?
