Thanks for the post.
If you are experiencing the same issue with multiple devices, it would lead us to believe that the issue is not the devices, but mostly likely your wireless network.
Can you provide more information about the issue you were experiencing? What specific Roku model devices were you using? What kind of wireless network were you using and who is you internet service provider?
With more detailed information, we will be able to assist you further.
Thanks,
Danny
