Worsening Internet Issues

Hi, the issues I'm having seem to be multiplying... it started with latency spikes which could be attributed to all sorts of stuff. It's moved on to momentary disconnects, prolonged latency issues, unstable power levels, massive amounts of "uncorrectables" and partial service notes in my event logs... on top of a Comcast phone tech canceling my last appointment that I set up because the issue was supposedly found and fixed! Just a heads up though, it wasn't and has worsened. I'm a bit irritated about that as I was told it was being canceled and had no other option. How's that for customer service, eh?

Re: Worsening Internet Issues

The upstream power is too high 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.

Re: Worsening Internet Issues

I already booked a tech to come out and visit! A woman with a super heavy accent canceled my appointment and told me it was fixed!

My latency is up 35-40ms from the average now.

Re: Worsening Internet Issues

The downstreams are way out of spec now ! You have some wide intermittent fluctuations going on there. They should not flux more than 3-4 dB. 

 

Good luck with the tech visit ! Please post back with how things turn out.

Re: Worsening Internet Issues

What's even better is that my internet is off and on right now at this moment. It keeps disconnecting or is giving me garbage signal and power levels I can't use.

So, I check the outage map and it says everything is fine! THERE'S LITERALLY AN OUTAGE NOTIFICATION WITH THE ( ! ) IN MY AREA. Comcast tools are a joke... please fix your stuff or I'll be forced to go to Centurylink!

The outage seems to have cleared, but I am still concerned about the power levels I'm receiving.

Re: Worsening Internet Issues

I've swapped modems to an older model and am still having trouble. So, that mostly rules out the modem being the culprit. This modem is also still recording T3 Timeouts, partial service, and Sync Failures... along with really high amounts of uncorrectables.

Re: Worsening Internet Issues

Have you re-booked a tech visit ? This can't be fixed remotely by phone.

Re: Worsening Internet Issues

There was an outage taken in the area the following day of my last reply and it helped for a little bit, then did the same thing. The day after that they took another outage and that helped for a while until now.

Now, I have 108ms ping with 375Mbps dl 0.62Mbps ul and 80% Packet Loss...

I have a super low opinion of Comcast's reliability, customer support, and products right now... to say the least.

Re: Worsening Internet Issues

Update: They've declared another outage! My internet is fine now, despite the outage in my area until 4pm. Funny, when it was affecting me last night... NO OUTAGE! It's like the "outage detector" is a farce and someone just designates it manually.

How is a company this technologically inept in the current tech climate? Sheer determination and willpower?
