Why do I keep getting disconnected from the internet while playing an online game.?

I am currently playing a Chinese online RPG game, since the server is in China, the connection is somtimes unstable. At home, I have a desktop and a laptop, both connected to the same router. The cable company we are using is surewest. When I'm playing on the desktop, it works just fine. However, when I play the game on my laptop, I get disconnected from the game about once every hour. At first I thought my laptop was broken, However, when I brought my laptop to college and used their wireless internet, it stopped getting disconnected. So I thought maybe our cable company didnt support connections for two computers. Now, I've moved into an apartment with my friends, and we got the highest speed internet from comcast and the samething happened again, my laptop started getting disconnected from the game. I don't think it has to do with the cable company since comcast internet is way faster than surewest, and my desktop never got disconnected using surewest. So I'm very confused...Can anyone explain to me what's causing the disconnections and how do i fix it?
