Unstable upstream

Hello, my internet has been very unstable in the past week. I'm currently using a Netgear Nighthawk CM2000 modem paired with asus router, and I've been experiencing connection issues every 1-2 times hourly. My modem page says there is a upstream problem. Also the xfinity app shows all of my equipment is offline, when it isn't.  Please advise!

Here's the cable diagnostic from my modem

Cable Diagnostic

Status: Poor

Action:
[Partial Service]
If the Partial Service mode does not go away within a few hours (Click the Refresh button after each step):
1) Make sure the coaxial cable is tightly connected.
2) Remove any unnecessary splitters.
3) Replace any required ones.
4) Contact your service provider for troubleshooting help.
[Upstream Power Level]
Try these actions (Click the Refresh button after each step):
1) Make sure the coaxial cable is tightly connected.
2) Remove any unnecessary splitters.
3) Replace any required splitters.

CM Status: Good

Downstream Status: Good

    Downstream Power Level: Good

    Downstream SNR Level: Good

Upstream Status: Bad

    Partial Service: Poor
    Cable modem is in partial service mode. Your service provider might be under maintenance. Most of the time it won't affect your traffic and will automatically clear when work is complete.

    Upstream Power Level: Bad
    Upstream power is poor (59.3dBmV). The recommended level is from 30 to 55dBmV.

The upstream power is way out of spec (too high) ! And only two channels are locked in. The downstream power is a bit on the weak side as well.. That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, latency problems, and the un-bonding of channels.

In an effort to try to obtain better connectivity / more wiggle room, check to see if there are 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 from Home Depot, Target, Wal-Mart, etc. Splitters should be swapped with known to be good / new ones to test.

Also check the coax cable for any damage such as cuts, nicks, abrasions, kinks, sharp bends, etc.

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.


Good luck with it !

Thanks for a very detail explanation!  Nothing has changed with my setup for the past 2 years so I'm not sure if something happened to the cable outside during the storm.  I sent the request to Xfinity and somehow got a message today stating that the problem is resolved.  I just run another diagnosis and the upstream problem is resolved and now there's 32 channel locked on downstream and 6 on upstream.  I'll keep an eye rest of the day and see if any recurrent problem.

This is the current diagnostic log now.

Cable Diagnostic

Status: Good

Action:
Your setup looks fine. If you can't access the internet, make sure you properly activated the modem. If modem has been activated and you still can't access the internet, contact your service provider for troubleshooting help.
If you can access the internet but has other internet issue, the Netgear Cable Knowledge Base can provide additional troubleshooting info.

Apparently something intermittent is going on. You should consider getting a tech out to investigate as stated.


Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it up to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home. And if the problem is found to be on their side of the demarcation point, there will not be any charge.


Good luck !
