This morning I received a text notification that planned maintenance in my area had been completed. Since then, I’ve been experiencing internet connectivity issues. Current symptoms: • Upload speeds: ~0.06 Mbps • Download speeds: Normal for a few minutes, then nothing for a few minutes on and endles

This is yet another post for the constant drops in internet service related to the "Time Not Established" error that is repeated over and over again in the Event Log for the Motorola MB8611 modem. I have researched this issue in this forum and have discovered many others with the same issue - and it

My Motorola MB8611 cable modem (Hardware Version V1.0, Software Version 8611-19.2.18) logs critical events of type "UCD invalid or channel unusable" every few days and sometimes multiple times a day. My Comcast connection will go down for a few minutes, and then come back up. Using the Xfinity app o

I’m on the 2 Gbps plan using my own Motorola MB8611 modem. On the modem’s status page I only see 34 downstream bonded channels (DOCSIS 3.0), and no OFDM downstream channel listed. My speedtests top out at about 1.3 Gbps. Since DOCSIS 3.0 tops out around 1.3 Gbps, it looks like my modem hasn’t been p

Hello, We've had constant signal drops for years now on our Xfinity network. I've swapped out modems and routers.

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. Upload speed is still capped at 40MB although package states that it should be 200MB. Tried all standard processes ( rebooting, disconnecting cables etc. . Please

We have "up to 1300 Mbps down/up to 35 Mbls up" service tier and are using an MB8611 modem. Things look okay on diagnostics with the exception of a very high number of uncorrected vs corrected errors (roughly a 2.5:1 ratio) on the downstream channels: Downstream Bonded Channels Channel Lock Status M

I think I'm having the same issue as this one. I recently moved to a new home. I had xfinity in my old place, and I never had problems with connectivity. 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
