Counter-Strike: Source Connection Problems

Hi, I recently received a new computer for Christmas and it runs a lot better than my old one. First thing I did was download CS:S and ARMA II, two games that I couldn't play on my old computer. At first Counter-Strike was running fine, but after I downloaded ARMA it began to have little connection hiccups which have screwed me over more than once. Then those hiccups became more frequent until eventually I could only stay in a room for about 2 minutes (1 round) before it would give me the WARNING: Connection Problem text. Then it seemingly fixes itself, only everyone on the map is invisible to me but they can still kill me. I try leaving and rejoining, and that fixes the invisibility problem, but the cycle just happens all over again. My ping is usually around 44 and I have a 5.71 Mbps down/ .42 up connection.

I also have an Xbox 360 and a PS3, which I also play regularly and rarely get connection problems on those consoles.

Please help, this is extremely frustrating to deal with and I'm trying to get into competitive pc gaming. I highly doubt that it's my connection, because the internet works fine on everything else, even ARMA II. Only counter-strike has problems.

Have you tried power cycling the Router?

How exactly would I do that?

Pull the power out for 10-15 seconds then plug it back in.

I did that but it didn't change anything. My internet worked fine before I started gaming on this computer. My last computer also had a wireless connection to the router.
