Random Disconnects at night after Outage 2 Weeks ago
For two weeks after there was an outage in our area we have been having random disconnects that cause interuption of service for 10 seconds at a time.
This happens on both Wireless and Wired Connection.
Have reset the Modem and router and there is no change in it happening.
It seems to happen more at night then it does during the day.
In the logs of the Modem see the following events all the time.
RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW
Dynamic Range Window violation

Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
What is the exact make and model number of the modem ?

The downstream power is on the low / weak side and it may be intermittently fluctuating even lower 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.

Dont have any Coax cable splitters in the line.
The Coax Cable is only about 3 feet long from the coax port in the wall from the wall. Tightness is good as well.
Need to check the connection.
