How do I troubleshoot erractic Comcast Internet Speeds
In the past year I have averaged 28 mbps with Comcast High Speed Internet. Recently the service has been unpredictable..Per speedtest.net one minute I get a download speed of 28 and if I try the speed test 5 minutes later it is 3 mbps. It has been so erratic at times I can not work on the computer connected to Comcast and am forced to use a T-Mobile Hotspot. Note I have tried multiple computeres wired into the modem with the same speed results.
My setup is a:
Cable Modem
A PC directly wired via ethernet into the cable modem
Comcast has said they have done everything over the phone they can do and will send a tech out over the weekend. My fear is they are going to immediately blame it on the cable modem and tell me to buy a new one without researching my issue. How do I prepare for the tech coming out so I can avoid the "go get a new modem" response.
Note the modem is only a few months old. It is a DCP3008 CISCO Cable modem. The Cable connection comes into the house at the basement and then is connected to a splitter. Once branch comes upstairs to my cable TV which is fine and the other branch from the splitter comes upstairs and connects to my cable modem.
Note I will go downstairs tomorrow with the modem and connect the income signal from outside into the modem and see if that makes a difference....so far I only checked downstairs that the splitter connections were fine. It was all put in 6 months ago and it looks tight.
Do they sell anything at a MicroCenter in terms of a tool where I could test the speed outside of the modem ?
