Intermittent Slow Connection

[Steazle]

Hello,

Over the past month or so, I've had intermittent connection issues. I pay for 600Mbps service, but on occassion I see my speeds drop to a consistent 60/90Mbps. Sometimes this will correct over night or during the day. Since I live in a small apartment building, I don't really have access to the cable lines outside of my room, but I can confirm there are no splitters inside my apartment.

When I talked to customer service, I was told they didn't see anything wrong on their end, but that they would continue investigation in the background and maybe send a tech. I never got a case number to follow up with, and no one has contacted me about this and it's been a couple weeks. I figured one of you helpful few could confirm that my numbers are slightly out of spec. (My speeds are satisfactory right now, but when they aren't, my Uncorrectables are in the millions.)

There is a problem with the downstream and the upstream power. 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.
