SLooww CHICAGO supposed to be 18mbs business actual 1mb

SO getting really slow numbers from speedtest.net and YES I know what I am measuring without using a service that gives an "enhanced" reading.  ALSO the icon ( bottom right of business account page) says "service ok" which clearly does NOT cover speed!!!!

 

I also ran a few ping tests from a linux machine I use and for good measure reset the modem several times including one hard reset.

 

I pay for 18mb BUSINESS so this is not great I am in Chicago

 

set up the account about a month ago and had no problems until this week

 

1 SO my questions ARE who do I EMAIL to get this resolved?

 

2  how do I check for system problems using the web, I tried using the instructions online BUT they don't seem to work for business accounts.

 

here are the signal details. Any guidance appreciated

Re: SLOOOWWWWWWW CHICAGO supposed to be 18mbs business actual 1mb

Hello majokong and welcome,

 

Your Downstream power level is clearly out of spec. You need to contact 800-391-3000, have a technical internet agent provide a technician to come to your business to correct your wiring, splitters, or modem root cause issues. 

 

Hope this helps you out.
