How can I fix my downstream Channels?
I have included my status report for review and I wondering what might be causing the issue? I have trouble getting the speed I am paying for ( 1GB ) getting online 40Mbps on average. Normally it happens half way through the month as I reach 1TB of usage. It has has a very hard time staying connected consistantly even though my connection says it is there and internet is up. The lights on my modem are all on showing an active connection as well. Please let me know what other information I can provide you to assist!
Thanks!

The SNR's are too low / out of spec. 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.

So I honestly dont believe I need any splitters at all to the house. Why would I need more than one line running in if I don't currently nor in the furture plan to have cable TV?
In theroy, this means I only need one line runing directly from the hookup to my modem, correct?
