Internet speed very unpredictable
Posted on 2014-12-08
Hi, I have noticed for the past few weeks that my internet speed was very unpredictable. Many times I would get timed out before I could open a page so I had Comcast come out and they installed a new cable to the house as well as a new modem. The installer tested the speed in SAFE MODE and he got 51 Mbps down and 10 up. That is what I am suppose to get under my plan.
Problem is that when he re-tested it under normal startup, he got 12 down and 5 up. He said the problem now is with my computer. Something in my computer is slowing things down big time (only with regards the internet). How can I do a diagnostic on my own to see if I can find the culprit? I'm not familiar with the technicalities of the operating system so I am thinking more along the lines of temporarily shutting down programs to see if its one of the programs. Also, how can I go into safe mode so that I don't do any damage? Thanks
