This problem started with the last update on May 23, 2023. It happened just a few times until this past week when we had a power outage and now it's happening at least twice an hour for me. I have to go through and reconnect to the internet as if I'm starting from scratch, even though it clearly shows the signal strength is excellent and there are no issues with anything else connected to the internet including the smart TV the Roku is being used on. I've reset the wireless on the Roku, the TV, reset the modem, tried to follow the instructions on an old thread explaining that my Roku Express only works on 2.4g and only on b/g/n which apparently was changeable on older modems but due to xFinity's idiot wisdom, is no longer an option to change with their xFi modems anymore so that's not doable. I will say I've had their modem for months and the Express worked fine until this last update! This is not the modem! But the power outage exacerbated the problem.
No, it's not on one specific channel, no, it's not at one specific time of day, it's all day long, no, I would fill an entire topic if I was expected to sit here and continue all day to go through hitting the home button and back button and giving you info after info over and over again about this problem. I have four Rokus of various levels in this house plus a Roku TV and at this point, with the problems I've had over the last year, we won't be buying Roku again. This past year has been one problem after another, you cannot call for technical help, you cannot chat for technical help, all you can do is post here because any other support takes days and the hoops to jump through are ridiculous. I am fed up. Watching TV shouldn't be this hard.
