My G34 gateway was rebooting a few times per week. Arris replaced the G34 and the problem persisted. I was also getting pixelation on my TV screen.
Comcast detected a problem with my line and sent out a tech. The tech also saw some unusual errors on my line. The tech installed a MOCA filter on the coax line coming into my house. Since the filter was installed my Gateway has been stable for over 3 weeks and the TV picture is better.
If you are having problems with your Arris gateway rebooting randomly then I suggest you get a MOCA filter installed.
