I recently upgraded my internet plan to the 1 GB package. After several support calls with xfinity support my download speed remains the same at around 700 Mbps and my upload worsened to 6 Mbps from the usual 40 Mbps. I bought my MB8611 last year and have been using it in preparation for the GB+ spe

Hi all, Since around July 15, I’ve been experiencing frequent short outages, usually twice a day, lasting about 2 to 3 minutes each. These interruptions have been happening consistently, often around 9AM and 10:00 PM, and are disrupting important business calls and meetings. The modem logs show: UCD

I've attempted to use the chat feature but it is broken. After speaking with someone else in my area who has the same internet plan as I do, I realized there is something wrong with my internet plan. This is not a technical issue but the plan itself. I also found other information that indicates the

After upgrading to x2 service and getting Netgear CM3000 modem internet speed increased from ~900 MB (Motorola MB8611) to 1,4GB download.

We have "up to 1300 Mbps down/up to 35 Mbls up" service tier and are using an MB8611 modem.

I moved my whole setup, unchanged, to my new place, and now I keep losing internet connectivity every so often. I have to turn the modem off and o

I've been using Xfinity for years as my ISP and have never experienced these internet issues. About two weeks ago recently moved to a new city and since then we have been experiencing intermittent disconnections to our internet. We never had these issues at the old house and we are also using the sa

I have 3 devices listed on my equipment page. I would like to remove Motorola MB8611 and Arris S34, and keep the Motorola B12 modem.

Hello, A few days ago I updated from 1g to 2g, with the `Up to 300 mbps upload`. I have gone through 2 iterations of the assistant rebooting my modem, as well as activating it. My upload is still capped at 40 Mbps. What does Xfinity need from me to remove that hard upload cap? The details of my Xfin

How do I know this? Because there are dozens of boards with 100's of users who have the same exact issue. Why has this never been fixed and no resolution ever offered? It was purchased based on it being a recommended model by Xfinity. I bought it after you stopped supporting my previous model which,

My speed tier should get me up to 2 Gbps, however about 6 months ago my speeds have dropped, I barely get 500 Mbps now. I use a router but even direct hardwire from my desktop computer to the modem doesn't get any better speeds. I've replaced my modem with one on the Xfinity approved modem list - Mo

I have been dealing with constant internet outages for going on 3 and a half months. I've gotten a "new" replacement MB8611 modem from Motorola and an Xfinity tech came out to run a new line from the pedestal to the house. Still getting 10 or more outages per day. The closest I can come to a diagnos
