Thanks for the post.
Have you tried changing the wireless channel on your router to see if that helps the issue you are experiencing? Who is your ISP (internet service provider)?
In addition, have you tried connecting your Roku device to an alternate wireless network, such as a mobile hotspot, to see if you are able to connect to internet?
With more detailed information, we will be able to assist you further.
Thanks,
Danny
