Two days ago, I was on the internet, and then I suddenly lost connection. The icon on the right of my task bar shows that I am connected, and when I called my provider, she said that I'm connected too. Now two days later, I was able to access the internet again for just a short moment, but then I lost connection again. I tried using Chrome, Opera, and Internet Explorer, and I can't get online, and there is no connection problem being detected. How is this possible? It feels like there is someone on the other end disconnecting me, and it's driving me crazy.
I use a Windows 8 laptop. I have wireless connection and I use a router for my internet. I do also have a cable for the internet that is being used. Other computers and phones are able to connect, so I assume it's a problem with my computer. No problems were detected with the troubleshooter.
I should probably also add that I followed advice from a few people to help speed up my computer (in case any of this messed it up). I did the following:
Deleted all %temp% files
Deleted all files in Prefetch folder
I followed many of the steps from this web page http://www.wikihow.com/Speed-Up-a-Slow-Windows-Computer-for-Free
I followed the steps from this video https://www.youtube.com/watch?v=s1I792ze86c
