strange Send/Recieve internet problem

[Marajade]

I've recently run into a very strange problem with my computers connection. Every so often my computer will simply stop sending or receieving new information. The first time I simply figured it was a router problem, and after a quick restart it worked again.

Second time it happened, was on skype, and again everything froze, but I could still hear the other people on the line, but they couldn't hear me. Things continue to work if they were already connected, for example I'll be playing LoL and not until the game ends will I notice that everything else has stopped working. When you pull up the network information, my computer is fully aware that its connected and finds nothing wrong, yet no program can connect to anything.

It also isn't the modem/router, since other things such as PS3 and laptop, continue to work. The current fix for it is to simply log off and log back on to windows.
