Thanks for the post.
What specific Roku model device are you using?
For customers who are using a Xfinity wireless network, we recommend changing your router settings for the 2.4 GHz band from g/n to b/g/n, as customers have stated that this helped resolve their issue.
For troubleshooting purposes, have you tried connecting your Roku device to an alternate wireless network, such as a mobile hotspot, to see if you are experiencing the same issue occur?
Please keep us posted what you find out.
Thanks,
Danny
