Random disconnects at random times? :O

Hello!

I'm playing on Lordaeron realm, and everything's running smoothly, except for one little problem I've encountered...

I get disconnected from the server at random times after 5 seconds of being in game. (I usually just log off when I see it starts happening, because it's relentless and it happens at the worst of times.)

Most of the time I'm fine, I can play for hours without interruption, but when it starts I know it's going to be a struggle to get back online for at least 20 minutes. This isn't such a huge problem, but for late game - PvP and raiding, it's going to be a huge problem. (Battleground-and-dungeon deserter, anybody? About to down a boss, and there's a 1000 person queue waiting for you on the other side of a DC?)

Anybody have some suggestions on how I can resolve this issue?

Thanks a lot for your time reading this :)
