new modem, new coax cable, new ethernet cable, same speed issues

Hi all, 

 

been having a lot of connectivity and speed issues. I have dealt with comcast support 3 or 4 times last week who were trying to trouble shoot and eventually just said it was my modem (as usual). I replaced my modem, the coax cable from the wall to the modem and the ethernet cable connecting the modem to the wifi router. I've also tested speeds directly plugged into the router to avoid wifi and am still having issues. I even went outside of my appartment and ensured all the lines running into the building were tight, which they were not. 

 

still, after all that I am having issues. I was having really bad SNRs, even with the new modem, but after tigthening the cables outside it seems to have resolved. That said, I am still getting a lot of "corrected" and "uncorrected" counts in my status per channel and my error logs shows some T3 errors. 

 

My speeds fluxuate from 1mb to 200mb. Doesn't seem to be any consistency to why it fluxuates. a lot of these tests are being ran when my laptop is the only laptop on the network, or my laptop and my spouses work laptop (just using basic office apps) are on the network. Below are the logs. Does any one have any thoughts? I want to try anything else I can before my 5th attempt with Comcast tech support. I also wanted to upgrade my service to gigabit but I don't want to upgrade it if im only going to get 40mbs download on average. 

 

thanks!

Re: new modem, new coax cable, new ethernet cable, same speed issues

The downstream power is a bit on the weak side. What does the upstream power look like ?

Re: new modem, new coax cable, new ethernet cable, same speed issues

@EG : sorry for late response. I work in cybersecurity and as you can expect, things are a little crazy with COVID (and another reason I need my connection to be stable) 

 

Upstream power is fine.

I can say since this post, I have gone outside of my building and tightened every cable conntecting to the building (just a 4 unit appartment building so it didnt take long). You can see a huge change in my downstream readings, as seen below, but still not getting ANY where near the gig speeds i am now paying for. The only thing left i have to replace in my setup is my wifi router, but it doesn't make a difference since im not getting those speeds while directly plugged into the modem, or on wifi. either way i get the same speeds. anything ranging from 40-240 down, while my upload speeds seem to be fine and what im paying for (35ish)

 

did also see some error messages I haven't seen in a while. they are posted below as well.

rebooted the modem my self, I've also unplugged it from the wall and coax for a bit (we had a nasty storm so I didn't want the new modem getting fried). so its had proper time to clear memory and noise from the cable line.

Re: new modem, new coax cable, new ethernet cable, same speed issues

The upstream power is on the high side (almost out of spec on channel #1 and it may be intermittently fluctuating even higher to out of spec levels. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.

In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test

If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
