Ok, so I'm having a problem with my wireless connection. Even on my computer, it randomly loses its connection for like 2-3 seconds at a time. So when I try to load pages, every like tenth page or so comes up with a loading error and I have to reload it. This wouldn't be a problem, but it also happens with any online games that I play, and I just get a message saying I've lost my connection and I get disconnected from the server. It was never this bad before, but now all the time on games like CSS or Zombie Panic! Source, I get random disconnects all the time. In order to play normally, I have to disconnect my router and connect straight to my modem, which is a pain in the ass to do everyday.

My modem is a D-link WBR-2310. Any help would be appreciated. Thanks.
