Hi there, you probably have already found a solution to your remote control challenges but I wanted to share with you and the community what worked for me. Another user suggested changing the wireless/wifi settings on the Roku from 5G to 2.4G as there could be signal interference between the streaming stick and remote. I did what they suggested and as I write this, the remote has been working perfectly for a week now. Prior to me making the change, I'd be lucky to get 24 hours out of my remote, with most of the time only an hour or two.
So in summary, take a look at your Roku wireless settings and if it's set to a 5G network, change it to 2.4G; if it's already set to a 2.4G, try the opposite and change it to 5G!
My Roku 3800X is experiencing the same problem. SN: CT3791407212 @RokuDanny-R
I am experiencing the same thing. I have done all the troubleshooting techniques. Is it just on it's way out?
