Go to Settings/System/About and look at model of your Roku Streambar/Soundbar
If you have the 9101, possible that your network is using DFS channels (52-140) which this model does not support. https://support.roku.com/article/21332729601687
Try disabling DFS in your router, if applicable and see if that helps resolve issue.
Post back the Roku model number, your router model number, and any network settings you are using. Also include any error message numbers you are seeing while connecting.
Have you tried using a mobile hotspot for connection (if available to you)?
