Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
If you are powering your Roku by plugging into the USB port on the TV, try powering from house power via the USB power adapter that came with the Roku. Many USB ports only supply 0.5 amp or less which is not enough to power a Roku reliably.
If you don't have the Roku adapter handy, any other you have from another device should work as long as the fine print on it says it outputs at least 1 amp.

Same happening here this morning. Did you just have to wait it our or did you do anything? I'm tired of it resetting itself and I have to set up the wifi connection and passwords over and over again. I'm old, I can't remember all these passwords and forget where I write them down. LOL Sigh
