slow slow internet spotty connection on extreme 150

so i have been having alot of trouble with my internet connection. this has been going on since sunday evening. I was prompted by customer service that perhaps it was the modem.. So I went into a comcast store and had the modem swapped for a new one.. come came home, same issue.. I called cs again not once but twice. we had it worked the first call, then it dropped down in speed again.. this last call it was suggested that perhaps my wires were suddenly losened on thier own.. We played around with settings and network names some more.. here is the speed test I just took on what is supposed to be extreme 150...  they did suggest a service call that would cost me 60 bucks and another day of waiting to get cable fixed.. I dont have the 60 and the moment and frankly I am wondering if that might not be better served by switching companies at this point

Re: slow slow internet spotty connection on extreme 150

The downstream power is too low / out of spec and may be intermittently fluctuating even lower out of spec. That can cause random disconnects, spontaneous re-booting of the modem, and speed 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.

Re: slow slow internet spotty connection on extreme 150

thank you very much will check for corrosion and such I do not see a splitter between wall outlet and the modem so it maybe the line is old as well.. If that does not work along with trouble shooting the connection will go to next step of contacting a tech.. thanks again for your help

Re: slow slow internet spotty connection on extreme 150

weill do, so far I checked the connections and everything seems ok. I may try and replace the cable coming from the wall as it is an older cable.. umm I did not see any corosion on the center pin that is in there on either end.

I did do a ping test, and I did have a few time outs plus at least one long connect time of : time=3016ms
