World of Warcraft, odd connection issues

[Kaddrix]

Atm I'm having odd connection issue, mainly when running World of Warcraft. I'm connected to the internet through a router connected to a main computer 1 floor away from me using a cable modem. I don't know much about computers, but what I do know is without any computer position changes, I USED to have a connection with a 54MB/s transfer, that being considered "Very Good". Now, "Very Good" is only 18, but it oftenly drops to 1 or 2 MB/s, lagging me out of World of Warcraft. It only really effects World of Warcraft. Never disconnects me from AIM or messes with whatever pages I'm browsing, for example I'm on World of Warcraft now, telling someone I'm lagging over AIM, and doing this. The only thing thats lagging is WoW. I have a Linksys wireless adapter (desktop PC) version WMP54GS, the router is Dynex, and the modem is Linksys. If any additional information is provided, please let me know what that is and I'll repost as soon as I can, but please keep in mind I'm kind of a computer noob >.< thanks to anyone who posts in advance
