Upload Very Slow - .05 mbps

 
Im having major issue with my internet. My upload is horrible and my download is fine. I had a tech come out to check the inside of my house, he put the new Modem - CGM4140COM - New splitter.    I'm still have the same issue and it been happeing for 4 weeks straight. I can never get a straight answer with the tech. I always get the run around.   Please help me Smiley Sad

The upstream power is approaching the high side but it may be o/k if it's remaining stable. Ever notice if it intermittently fluctuates higher in to the 52 dB area ? There may some type upstream channel / return path impairment of some sort.

Re: Upload Very Slow - .05 mbps

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.
