I'm having simliar problem, here are my stats. Any help would be appreciated.

[EG · Accepted solution]

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, and latency problems.

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.

Thanks! I'll try that - there's a splitter that was installed by a tech previously. I'll remove and see how that works.

@EG, 

I've removed the splitter, what's your take on the numbers I'm seeing now?

I appreciate your input. 

[EG]

A bit better if they hold stable. Bottom line: live with it for a while and see if the problem returns. Good luck !

[CF88]

Thanks!

[EG]

Quite welcome ! Feel free to report back here if the problem returns.
