I upgraded to gig internet and bought a SB8200 back in April, but starting a month ago I've been experiencing multiple "outages" on a daily basis. I've had several technications come out to the house to look at the line, which they finally replaced last week. When the problem persisted a tech came back out to see if I needed a custom line, but saw no reason to install one as the box was less than 250 yards from my house, and because based on his test I was getting over 1000mbs from my cable (I saw the speed test he ran on his machine). He told me he believed the issue was being caused by my modem.
To test this theory I decided to spend all of yesterday working downstairs with my laptop connected directly into the modem (instead of connected via router), and noticed that my modem was continously resetting itself about every 3 minutes. When I called Arris, they informed me that I am currently receiving 41 downstream channels from Comcast, which is 9 more than my SB8200 allows for, and that this is causing the issue. After an entire day of speaking to several different Comcast agents, I was finally able to convince a supervisor to "provision" my modem. She said she saw that there was an issue and that the provision should fix the issue. Fast forward to the next morning and I am still losing internet every 10 minutes, and can see that my modem is continuing to reset itself.
Does anyone have any idea what is going on? Are the 9 extra channels I'm receiving causing this issue?
Yes. Please post a screenshot of or a copy and paste of all of the text of the downstream channels, and the upstreams as well.
I am now receiving 32 downstream channels but my modem still continues to contiously reset.

FWIW, the Arris rep was full of baloney or untrained. That modem's tuner is only physically capable of delivering a max of 32 channels ! Arris has been conning people in several ways lately for some reason..............
