do you have a screen snip of the cable connections page and the logs? 

That lets us check the signal from the isp.

 

Have you noticed if its mainly device on 2.4gh? 5ghz? wired devices?

    I notice the 5ghz signal only becauase my smart TVs are on it. My computer is also usually on 5ghz which I notice the most.

        Your power levels from the cable connections page looks spot on. But your getting power violations on the logs ant t3/t4 errors with sync errors. They tend to indicate line issues. Might be worth having the isp checking the line. 

        I'd also check to see if you have any splitters, amplifiers, or attenautors in line and remove them. 

        How frequently is it happening?

        A reboot is the only thing that fixes it? 

        Do hardwired devices have issues when its happening?
