I am having the exact same problem, I have reset the router and the roku device and everything else works including a firestick, voip phone, 2 computers and my cell phone all connect to the internet but my roku connects to the router, says that the connection is good but has no internet service. Every other device shows internet service is up and running. I have found generally that ROKU devices are cheap pieces of **bleep**, my other one kept saying low voltage even while connected to a rOKU power supply, finally threw it in the trash and got a firestick. The firestick is well made, great product and I will probably replace this piece of **bleep** with one plus amazon gives support for their firestick and there seems to be no phone or technical support for this piece of crapl Also I noticed that there is a change in the wireless setup last night - it now asks if you are at home or in a hotel. I suspect that this change has something to do with the problem.
