Internet is working on my roku tv but tv thinks there is no internet connected

We woke up the other morning and when I turned on my Roku tv the setup screen came up. This has never happened since I bought it and set it up two years ago.  I went through everything.  the language selection English.   Next was connecting to the internet.   did that  got the connected to Internet  check mark.  then said checking for updates:   We got an update is available but when I clicked on ok   got an error message saying can't be updated.  TV thinks there is no internet  on it but there is.  We are streaming with our firestick.   Now I can't get any of the free Roku channels    When I go to home there are only the devices connected to the tv that come up.  Not my paramount + app  or any of the Roku channels that I could get before the other day.    Is there any way for me to fix this.   I've tried to do the network connection reset  but I don't have a network reset option   just sign in to a wireless network.   Please help.   I don't want to have to do a factory reset if at all possible.
