Hi @Shannonstewart,
Thanks for getting in touch with us here on the Roku Community!
We'd like to be of support with this connectivity issue and we appreciate your effort in troubleshooting this. To assist, could you tell us if you've made some recent updates that might be related to this?
In addition, we could try to use an alternative network like a mobile hotspot to see if you're able to connect your Roku TV to it.
Please let us know more about this so that we can better isolate this case.
Best regards,
