Try rebooting the router (even though everything else is working fine) and try performing a Network Connection Reset on the RokuTV. (Settings/System/Advanced System Settings/Network Connection Reset/Reset Connection).
A little weird that it won't connect to either the hotspot or the home network though. Am assuming the hotspot password is different than the network password?
