CM2050V unstable after Comcast updated firmware
Same problem here in East Bay, California, starting late September. It stops responding every 1-8 days; a physical power cycle is the only way to recover it.
Xfinity Chat "reprovisioned it", b...
Comcast just pushed the old firmware (V02.01.03) to my modem, replacing the broken V09.01.01! Fingers crossed that the problem is solved.
800-COMCAST was totally useless for this problem. I was told that Xfinity never changes the firmware (apparently they don't even have the capability to do so), that I should contact Netgear for support, etc. Over 10 calls resulted in the same result. Two techs came on site, and both said that it was a modem problem, but would not/could not solve it because it was my modem. I was repeatedly told to rent an Xfinity modem.
DSL Reports was the only access to knowledgeable support. Although it was a slow interaction, they acknowledged the problem, investigated it, and said that a downgrade was forthcoming. Hopefully the company is rolling the downgrade out to everyone and not just those who find DSL Reports for help.

I'm using Firmware Version V9.01.01, presumably installed by Comcast.
Glad to hear they are taking responsibility. Thanks for letting us know.
Got this email from Comcast today. I assume they are referring to the problems in this thread. Mine seems to be fine and I checked it is running v 2,01.03
I just received an email as well:
We've noticed intermittent connectivity issues with your internet service and have identified the cause to be a defect with your NETGEAR CM2050V internet modem. NETGEAR is working on a software update that should fix the problem. Because the update may not be available for several months, we have taken steps in the interim to stabilize your connection and provide you with the best possible experience. These proactive measures should resolve your intermittent connectivity issues and provide you with fast speeds, but your modem may not achieve the full upstream speeds included in your Xfinity Internet package until the NETGEAR CM2050V software update is deployed.
This came after close to 3 months of trying to convince them that the issue existed, and that a firmware restoration (downgrade) was required.
