Unstable connection on nights that are close to below freezing

My connection since late November on nights when it gets really cold has been unstable with decreased speeds, dropouts, packet loss, bonding channel loss and wild changes in signal levels. This all happens when Temperatures outside reach 36F or lower. Once it warms up by about 9AM everything returns to normal. I've had a tough time getting help with this issue since it's intermittent and when a tech can come out it has warmed up enough where the issue disappears. Also since it happens at night if it is affecting my neighbors they might not notice it since it resolves by morning. I work nights so I might the only one catching this issue.


I've had 3 techs out so far and they have checked the cabling and put new coax connectors on all the cables on the house side. 1 also checked the cable drop coming to the house and everything looked good to him. Since this issue is so intermittent and hard for the techs to diagnose. Can my connection be put on a 24/7 signal log. So the instability can be detected? I'm almost 100% sure the issue is outside of my building wiring.

I have cable modem signal logs that correspond with the dates with near/below freezing temperatures with increasingly unstable signal levels with lower temperatures.

11/20/23 - Starting to get unstable getting packet loss and lots of uncorrectables. Also starting to lose downstream channel bonding. Temperatures that night 38F.

11/24/23 - Noticeable internet instability lots of packet loss wild swing in signal levels on the downstream bonded channels and channel loss. Temperatures that night 32F.

11/27/23 - Internet mostly unusable that night modem constantly rebooting having trouble keeping any channels bonded. Temperatures that night 28F.

12/16/23 Got a new modem so logs look a bit different. Unstable tonight as well. Losing bonding channels, packet loss, high uncorrectables and out of spec signal levels. Temperature outside currently 35F.

For comparison here are the signal levels at 10:30AM When it has warmed up to 42F outside and the connection is back to normal.

@Navitron Thank you for reporting the issue and for your investigation. I'm sorry that you have been dealing with the decreased services for so long. All network details are monitored, but it does help bring attention to an issue when there are multiple reports. Since, like you said this seems to be isolated to the evening hours it may be going undetected. I want to have this repaired for you so that you are no longer having the drops in connections. With having 3 technicians out already, I may be able to reach out to our local team directly to have this addressed. I see that you sent us a direct message as well. I'm sorry that we did not receive it sooner. Whenever posting there may be a delay from us for a response, but if you want more immediate help, please use the customer service board here: https://forums.xfinity.com/topics/customer-service/602d5700e6b3965d18e3a5ae

I will reply to your direct message and help out with the connection from there. Thank you again for making us aware of this issue and for allowing us to help out!

I have been dealing with this same issue in the Denver area for over a year, they have replaced everything inside and out at least twice. I work from home and daughter does online college classes (and if you drop during an online test you fail as they assume cheating).  I don't have my own modem and don't know how to do logs like this person but I am super exhausted with talking to the xfinity app multiple times a day to check my internet connection and restart my modem.

YES^^^

I am in Colorado Springs and for over a year my speed drops very bad, alongside the packet loss is awful when the temperature drops. I replaced my modem last year which turned out to be a waste. They're now making me get an xfinity modem to prove its not my new netgear modem. The tech came and said it's not their service coax or my coax in my house. So I now await their modem with unusable internet. I'll definitely be expecting refunds when its all proven to be ISP side. Here's some ping plotters.

From Chicagoland 👋 

This happened to us starting Saturday Night (Jan 13) with the lowest temp being -8° (feels like -°30)

I was told go swap out my modem and I did so this morning. We had a good hour of flawless streaming until the same intermittent connecting / no connection found messages.

I've been on my 5G phone trying to troubleshoot further, we're getting a service call this Wednesday. Nervous that it'll all work when he's around and will continue acting up a night.

I have the same issue in Elmhurst. I have a mesh system to extend the WiFi and the technician said that everything was fine, it must be the mesh system, I explained that I get the same when connected directly to the Xfinity router but all he said is it looks fine now.

Experiencing the same in Logan Square, Chicago. I lose and gain WiFi several times a day with these below 0 temps. Xfinity’s chatbot is virtually useless and just suggests sending technicians which will result in a charge to my account for what I am confident will be a fruitless visit. It would be nice to at least get confirmation that these extreme temperatures affect service.

My neighbors in the same building, who use a different internet provider, aren’t experiencing any interruptions whatsoever and we will likely be switching.

I'm in Oak Lawn Illinois and have been experiencing this pixelation/skipping sound issues for the last couple of days sinc the bitter cold hit. A couple of times I got the "no signal" message on my TV. Tech resent the signal today and said she "cleared out the old signals" and I should be fine now. We'll, several hours later and same problem. Shows up on programs recorded on DVR as well. Definite lag time when using the remote too.

Hello original poster here for my problem the cold snap for my area is over and I have interesting information. Temperatures dropped to 15 degrees for 3 days straight on the 12-15th of January. The connection was actually pretty stable during the extreme cold.  Now it has "warmed" up to 36 F and the instability is back. It seems like just near freezing is the trouble temperatures for the equipment it's effecting. Maybe a frost freeze/unfreeze moisture ingress into the coax cable connection somewhere on the line creating instability?

Hello @Navitron. Moisture getting into the cable line, can cause issues with your instability. We can take a closer look at your signal and see if we see any issues on our end. 

 

Will you please send our team a direct message with your full name and full address?

I’m in the Huntsville. AL area and am experiencing similar issues. Once the temp goes below freezing, we begin experiencing pixilation on random channels. The lower the temp goes, the worse the pixilation. We scheduled a tech to come out, but by the next morning, the temp returned to upper 30’s and the issue resolved itself. By the following night, it returned as the temp decreased to below freezing.
