OK I tried asking in the gaming forum but it was no use.

A day ago I got CS and when I try to play it says that it couldnt contact server list or something.

Now, My computer is connected to a router, I heard that might be the problem but I dont know what to do.

I may have not explained clearly, my computer is connected to an antenna which receives signals form the router.

Otherwise try to use a third party server finding tool like all seeing eye or even xfire if you're desperate.
