Every few minutes the programming coming through Roku repeats the last 2-5 seconds.

Not only does it freeze and then at some point go back and repeat a scene sometimes every few minutes and sometimes hourly or rarely, but a more prevalent problem is when you arrow over to change the channel nothing happens it lags so you do it again and then it does two steps over. Also when you scroll it pauses and doesn't scroll then it finally starts to scroll but sometimes freezes. And more often than not when you're trying to scroll through channels it will reset and go to channel 3 no matter where you're at.

The spectrum app is garbage and I don't think they care. I've tried to find the issue with the channel changing mentioned above now for months and have been unable I've just started having the repeat problem that everybody else is talking about. I've removed the channel and added it back in and it improves the channel scrolling for only about 10 minutes or one or two tries at changing the channel and then it's right back to it.

I found a solution to this problem. I purchased a Netgear modem and turned on dynamic QOS (Quality of Service). This gives streaming video and zoom calls higher priority than other requests. I had a lot of bandwidth (190MBps download) and could not understand the need for it but it solved he problem. I do have 14 different devices in the house but not much going on besides a surfacing on a phone and streaming spectrum. I do have devices such as an Netgear AC1200 extender, Ecobee thermostat, and garage door openers that are on all the time.

I have the Netgear Nighthawk AX4300 that I purchased from Costco for $129. Great deal and better than the Netgear Nighthawk R7000 that I returned to the store although they both solved the problem. The AX4300 was WiFi6, better house coverage, and less expensive.
