Intermittent connection issues

Hoping someone here can help me figure things out. I've been fighting with intermittent connection issues on and off since I got gigabit service back in January. Sometimes things will work fine for a few weeks, and other times I'll experience issues which usually manifest themselves as very low throughput with high packet loss. On a good day I'll get a full 980mbps on a speed test. Today, the speedtests time out half of the time (refuse to even start) and when they do I'll get something like 10mbps down. Oddly enough, I usually get the full 40mpbs up. 

 

My modem is a Netgear CM1000. On a good day, it works fine with my router. The techs on the phone always say to remove the router, but the test results end up being exactly the same so I'm 98% sure we can eliminate that as a variable here. I've had several come out to my house, but every time they do the internet is acting fine again and they say the signal looks OK. The cable coming into the house is just attached to a 2 way splitter, which has been replaced multiple times by the techs. Usually I'd say the issues are associated with weather, but today the weather has been great. 

 

Just running a simple ping test, right now it works fine for a minute or 2, then will fail to resolve the host and time out for 5-10 seconds, then continue working again. Checking the router logs, there are tons of CM Status Event Type 16, 22, and 20 messages. Not all of them, but many of them correspond with the pings timing out. Running periodic iperf3 tests also usually results in a high number of retries (50-200). 

 

Here's a modem event log snippet:

Nobody on the phone or any of the techs who have come to the house have been able to figure this out yet. Crossing my fingers that someone here has more experience looking at issues like this to help me out!

 

I just had to retry posting this 3x because it kept timing out on me mid-post. This is so annoying, not to mention that it makes gaming impossible.

Re: Intermittent connection issues

Modem logs stopped spamming error messages at 2018-06-26, 02:55:29 and the connection has seemed fine this morning. Constant event logs messages prior to that, which appears to be a symptom of whatever the main issue is. Is anyone able to check some maintenance logs or something to see what changed to help nail this down? This is what always happens, and by the time the tech gets out here they say everything is fine and it just happens again in another day or week. 

 

For comparison, here are the signals now. The partial service notification has disappeared. Also, is the mess on channel 6 (477mhz) indicative of anything?

Re: Intermittent connection issues

Hi @tr1883,

Looks like you had a maintenance issue that has since been repaired. Just to be sure...

 

I've asked an employee to check the CMTS for real-time and historical RF signal reports from your modem. They can also check your local node/plant for any degradation or error reports. You can expect a reply in this thread.

Re: Intermittent connection issues

Thanks @nerdburg.

 

While we wait for the reply, if this was a maintenance issue, is there some term for it or something I can use when calling to report it?

Everyone on the phone tells me there are no issues in my area, so is this not data that they would have access to? I want to give Comcast reps useful information so that they can provide me with useful service, not deal with the runaround of rebooting and rewiring things just to tell them it didn't work. If I could call next time and say something specific and have a plan to fix it in minutes rather than days, it would benefit both sides.

Re: Intermittent connection issues

The issue has reappeared this afternoon. CMTS event codes 16 and 22, partial service in the channel info. Who should be aware of this to investigate the issue?

Re: Intermittent connection issues

Thanks Phill. Responded via PM. 

 

For keeping a common place for documentation, I want to note that the signal appears to have cleared up again, with the last modem log being from 2018-06-26, 17:31:52 which corresponds to I believe 4:31pm EST. I'm hoping that noting these times will help you identify the source of the issue.
