Using Roku Ultra wireless connection to XFinity router. YouTube TV is buffering even though internet connection is Excellent and download speeds shown as Good usually between 30-90+ Mbps. Checked download speeds on other wireless devices and always 150+Mbps. Roku device is less than 6ft away from router so its not weak connection. Tried rebooting everything, uninstall/reinstall app and changing HDMI ports. Problem just started but I've been using this same set up for over 18months without ever getting a buffering issue
If your Roku recently updated to 9.4.0 (Settings/System/About) then revert to 9.3.0: Home 5x, FF 3x, RW 2x, upgrade software, select 9.3.0
How do you revert to an older update?
Not sure how you missed it, but the post right before your post explains the process...
Got it, button sequence.
Looked cryptic to me first read, didn't catch that.
