Internet crashes while gaming

I have posted a similar thread a while ago(a few months before).
The problem is the following:
While I play Counter-Strike 1.6,the internet crashes once every 5 mins,I can't enter any page via IE9,the game won't start up for 40 seconds-1 min,or so,but the interesting thing is,I can talk on Yahoo Messenger,or my uTorrent keeps downloading w/o intrerruption.
The router's(I have a Belkin router,and I'm connected to wireless) firmware is up to date,and my Atheros AR9285's(network adapter) driver is up to date.
A while ago,it was doing the same stuff,but after I updated the network adapter driver it started to work fine.
Please,this is driving me crazy,I seriously need help!

ah,c'mon guys,a lil help here...

Because you are sharing bandwidth with everything connected to your network you may need to give priority to gaming as this is usually the most bandwidth intense thing the router will need to handle. I had to do this with my Netgear router and don't have many problems now when others are using the network - you will need to get onto the Belkin website to find out how to do it on your model but it certainly helped in our situation.
