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", but it is still failing.

 

Has anyone been able to resolve this?

Re: CM2050V unstable after Comcast updated firmware

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.

Re: CM2050V unstable after Comcast updated firmware

Power levels are good.

 

Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.


Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended. 

 

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

Be aware that the ISP is doing some mid-split configurations on there network. Something to ask them about.

Re: CM2050V unstable after Comcast updated firmware

How does one "Be sure the ISP provisions the modem correctly."?  I've been on the phone so many times with Xfinity, trying to communicate that this is the likely problem. I see that changes have occurred, as the firmware is newer and my upload speeds are faster.  Tech support does not seem to understand that this could be the source of the problem, nor the concept of escalation!

Re: CM2050V unstable after Comcast updated firmware

@Kitsap, I too am having problems getting Comcast to help me. My 2050V was rock solid for 34 months until end of September 2023, seemingly due to Comcast changes.

Are you suggesting to forgo the unproductive hours on the phone and my formerly beloved 2050V, and pay $15/mo for their modem/gateway?  (Comcast's competitors in my area offer only 50Mb speeds.)
@Kitsap wrote:


The sooner you start having Comcast charge your credit card for a gateway lease, the better you will feel.

 

My CM2050V has been in service since September 2021 and has not missed a beat.  The first firmware update was a few weeks ago as Comcast is working on their infrastructure for the mid-split configuration update.

You don't for certain.  That is where direct written communication with Comcast employees on the DSL Reports Comcast Direct forum or on the Reddit Comcast_Xfinity forum comes in to play.

 

What is the firmware version that is currently installed on your CM2050V?

NO!

 

You are quoting a post midway through a separate thread out of context.  You need to read the complete thread to the end!

 

I note from the cable information post in your other thread on this subject, you already have the upstream OFDMA channel in place.  Your situation, your installation, and the progress Comcast has made with the mid-split upgrade in your area is different. 

 

Your answers will come direct from the responses from the Comcast employees that support in DSL Reports and Reddit forums.

Re: CM2050V unstable after Comcast updated firmware

Comcast fixed my issue.. the modem was improperly provisioned inside their office and had nothing to do with outside plant. It took 4 weeks and 15 trouble tickets.. I think they just kept escalating it until they found someone who knew what he was doing which is close to impossible with Comcast

Re: CM2050V unstable after Comcast updated firmware

It's a painful process.  The Xfinity 800 number is useless. Comcast Direct finally provided the following on Nov 28, with no ETA provided:

This is a known issue, engineering team will be rolling back FW shortly.

I asked when, and the response was:

We are still waiting to hear back on the rollback, as soon as I get a date I'll share.

At least there appears to admission of the a problem.

Re: CM2050V unstable after Comcast updated firmware

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.

Glad to hear they are taking responsibility. Thanks for letting us know.

Re: CM2050V unstable after Comcast updated firmware

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

Re: CM2050V unstable after Comcast updated firmware

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.
