Unable to connect to Internet

We lost internet connection yesterday. Connection has been restored and all devices are working again except 1 of our Roku TV's. The network signal is strong, it says we have a wireless connection but no internet connection.  It brings up a message that says network connection help then asks if I'm at home or at a hotel or dorm.  When I click on Home, it goes through checking the connections again. Wireless connection comes back good. But Internet says unable to connect to internet. Can someone help me troubleshoot?
