Intermittent Outages

I've been having the exact same issues since the so-called enhancements were performed in my neighborhood. I have a tech coming out this Friday, but would like to see if I can learn anything here.

Having a very similar issue. I work from home and this is extremely frustrating. It makes it difficult to continue work calls.

What do the modem's signal stats look like ? Try getting them here; http://192.168.100.1 or here http://10.0.0.1 

Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.

What is the exact make and model number of the modem / gateway device ?

Is this with a WiFi connection ?

You need to use this address:  http://192.168.100.1

The downstream power is out of spec. 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 !

I don't have many outages but have had  severe lost of speed since the outside neighborhood "upgrade" to 10G.  Our internet was great before, but after they came and did outside "enhancements", everything has gone downhill from there.

Exact same thing happening here. Motorola swapped out for Nighthawk, 4 different techs have come out and changed all the connections, and nothing solves the problem. all started since the "upgrades" as well. 

Hello All,

I had this same issue some months ago.

I'm a computer tech with many years of experience, but missed the actual problem, shame on me.

After 3 visits from different techs, I finally landed an actual, will qualfied Xfinity employee that knew his stuff.

Replaced the entire ground system at the external box with lightning arrestor and all is now perfect.

Noise on the ground system is a real problem.

Hope this info will help at least in some of the cases.

Thank you for that additional info @Wolverin ! The original poster has not returned. 3-month old thread is now being closed.
