Do I need a Tech or ???

This past Friday, I woke to no internet.  After a dozen or so restarts, it was good again.  This morning, I woke to very slow internet (Speedtest says 1Mbps).  I have removed the splitter that came from the street into the house, so the only device connected it the cable modem, just to eliminate anything inside (we dont use the cable boxes anymore anyway).  Just wondering if there is anything else I can do or if i need to get a tech out.

Many of the downstream channel SNR's are too low / out of spec.

 

If none of the below tips apply, it would be best to get a tech out to investigate and correct this one;

 

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. 

Good luck with it !

Can't see your pics. Since you are a new poster, they need to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting them at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to them here.

Or copy all of the text of the status page and paste it into the body of your next post here.

EG, 

 

Thank you for the reply.  I have done all of the troubleshooting you mention before I posted, so I will need to get a technician.  Can you suggest the quickest way to get one out?  I loathe the call to xfinity that will take +/- an hour to get to the point where they agree to send a tech out.

 

thanks again,

-rich
