MDD timeout / Sync failure - causing disconnects every day or two?

I just moved from Colorado to Connecticut (I have/had Comcast cable internet in both locations).

I had no issues w/ stable internet in Colorado with my Arris Surfboard SB6141 (9 years old).

When I installed the same modem in CT, I was seeing frequent T3 and T4 timeouts and disconnects multiple times a day.

I purchased a new Arris Surfboard S33 (thinking the issues could be due to the old cable modem) and installed it a few days ago.

Well guess what... the S33 is also running into T3 timeouts, MDD timeouts and sync failures... although less frequently (seems to occur every day or 2).

Originally, I had the older SB6141 connected directly to the incoming cable (i.e. no splitters).

Currently, I have the S33 feeding off of a single splitter (but based on the similarities with the SB1641 I don't think the splitter/wiring is the issue here).

Here are the S33's status/logs...

Can someone help me out here?

... Arris Surfboard SB6141 ... Arris Surfboard S33 ...

Note that the SB6141 is no longer an approved device, while the S33 is a recommended device. See the "All Compatible Devices" link near the bottom of https://www.xfinity.com/support/devices (at the moment it points to https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2024-07-18_Full-List-of-Compatible-Devices.pdf, but this changes from time to time).

The downstream power levels and SNR values posted are pretty much perfect, but the upstream power levels are out of spec (too high), which is consistent with the timeout and sync errors in the event log. Network connection problems like this are often due to poor coax connections or damaged coax cable, usually in or near your home. Running the cable through a surge protector, a defective splitter, or too many splitters can cause signal problems as well. If there is an amplifier in the line make sure it's getting power.

If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you can't find the problem or you'd rather have Comcast take care of it and an employee does not respond to your message here, call them at the phone number on your bill or 1-800-Comcast, or use one of the options on https://www.xfinity.com/support/contact-us/. It's not likely they can fix the problem remotely. If not, insist they send a tech out to identify the cause and correct it.

If the tech finds bad coax, splitters, amplifiers, or connections in your home (even if Comcast originally supplied them) you'll probably have to pay for the visit (approx $100) unless you have their Service Protection Plan ( https://www.xfinity.com/support/articles/service-protection-plan, closed to customers that don't already have it). If the trouble is due to a faulty Comcast rental device or anything outside your home you shouldn't be charged.

@user_np741m

Thanks for reaching out to us, I am a customer as well would not be happy if my connection periodically dropped. Are awesome Xfinity app https://www.xfinity.com/apps is a great tool to troubleshoot your services if the service issues cannot be resolved via that remote troubleshooting our awesome app will schedule a technician to come out to fix the issues.

Have you tried disconnecting the splitter and running your cable line directly into the modem to rule out the possibilities of the splitter going bad, I had get a new splitter as I have my TV service and Internet running through one coax outlet?

Update... so we had a Comcast tech come out and take a look at things and he confirmed that the upstream power was too high.

He removed the only splitter on the incoming line (which was a brand new -3.5dB splitter that I had installed with the intention of running a MoCA network) and was able to get the upstream power down to ~48dBmV and said things were now looking "good" but that I wouldn't be able to put the splitter back on.

When I objected and said that at least 1 (probably 2) splitters would be necessary for me to run a MoCA network, he basically shrugged and said that maybe something could be done at the neighborhood box to improve/lower upstream power levels to a point where I could add splitter(s) (he said that signal levels could be "rebalanced" in some way).

He said that he would submit a ticket for another tech to come out and check out the neighborhood box to see if "rebalancing" was possible (this was last Thursday and to my knowledge, nothing has happened yet).

Looking at things over the last few days (after the tech came out and removed the splitter) upstream power levels do seem better around ~48dBmV but I have seen them as high as 51dBmV. However, we are STILL getting multiple disconnects a day along with T3/T4 timeouts.

Here are some recent logs from the cable modem (S33v2):

Another thing that is relevant... we started asking the neighbors if they have issues w/ Comcast internet and we have heard back from almost everyone (who has Comcast) that they have connectivity issues as well and have had issues for YEARS. One neighbor was so fed up that they switched from Comcast and to Starlink!

So it seems like this issue might be an issue with Comcast's equipment/cable coming into the neighborhood.

No idea what can be done about the issue now and am starting to lose hope that Comcast will be able to resolve this issue.

Anyone have any suggestions about what to do next?
