When I first got this modem, everything was awesome, fast, stable, low latency, and no Intel Puma chipset issues. But now I'm intermittently rebooting the modem up to 12 times a day when speed of my 500/20 Comcast service drops to below 0.3 mbps up and down. When we experience this issue, the modem never goes offline and the LEDs are all solid as if service is having no issues, but with less than 1mbps of service, it's impossible to do any work from home. The only workaround is power cycle, which may last from minutes to hours, before the next powercycle is required.
I called Xfinity support and they've put a 7 day watch on my account but insist that there are problems with all 3rd party modems and only using their rented modem will resolve the problem. It seems that Comcast has taken the totalitarian approach of forcing more rentals by denying support for BYOD modems.
I'm on firmware version 4.02.02 which doesn't seem to be current, but again Comcast says they can't update the firmware of personal equipment.
If needed, I can publish the log, removing the MAC address of my cable modem, but any ideas on how this can be resolved. By the high number of issues in both Netgear and Xfinity forums, my issue doens't seem to be isolated.
