CM2050V speed problems
I've seen several posts in here about speed problems with their nighthawk. Motum, I'm experienced in the same. I was getting my speeds at 1 point, but now the speeds have dropped. I'm paying for 1.2GB down and 200MBS up. I'm only getting 35up now. I've had several techs come out and several conversations with Xfinty but they keep telling me everything is fine. I suspect the latest firmware version is causing my issues itself however I've been locked out of my modem by Xfinity, don't think they can do that can they? How did others finally get yhier problem resolved

So here is the config. see anything unusual?
Power levels are on the lower side but with in specs.

Correctables and un-correctables are zeros which is good.
What Firmware version is currently loaded?
Please post a copy and paste of the modems event log page.

Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
What is the brand and model of the host wifi router connected to the modem?

Sorry forgot to post Router, it's a ASUS ROG Rapture GT-AXE1600 Quad-band wifi 6E. I'm sure you know the specs.
Furry,
Thank you for responding. I will post the log page when I get home tonight, I am using a CAT 6CABLE so good there

How did others finally get yhier problem resolvedOver the past week or so, Comcast has downgraded the firmware on the CM2050v modems across their system. The old firmware will not support the new Next Gen upload throughput (mid-split).
Netgear will have to revise the firmware and then Comcast will have it re-tested prior to deployment. Hopefully both Netgear and Comcast learned something from this evolution. I would not hold my breath for a quick turn around.
Thank you for your response. This is interesting. I have to believe when my modem was actually getting 150Mbs Up is when I had the latest firmware, it appears that when they put me back on Ver 2 is when I saw the degradation in speeds. So do you recommend another modem that will deal with this issue or is this a wait out the clock situation with Netgear and Comcast?

It is not just you, all of the CM2050V's on the Xfinity system have had their firmware reverted back to the V2.01.03. Users in the Next Gen upgraded areas saw their upload throughput cut back just like you have.
I do not know what value the increased upload throughput has to you and your use of the internet. A different modem and the hassle associated with a change out has a value that can be estimated.
I am not in a Next Gen area and the system upgrade may be a year or more away. Waiting for a firmware update has no impact on my use of the internet. The everyday operation of my CM2050V is definitely better with the old firmware.
Recommend you wait a few months and see what develops. Resolving the issue is definitely on the task list for Xfinity and hopefully for Netgear.
You should not be locked out of access to your modem. What happens when you put the http://192.168.100.1/ address in your web browser? Have you tried a different browser or cleared the cache on the one you are using? What is the brand name and model number of the router you have connected to your modem?
