Laptop IssuesFollow

Okay, My girlfriend and I both play Wow, I use a desktop and she use a laptop.
The problem is when we're doing anything "normal" we run fine.

But when we enter say AV or an instance with more than just the 2 of us, her lantacy jump thro the roof, (3k-11k ouch).

We're reconfigured all of her firewalls, but the problem still happens, maybe someone can give advice on what is causing this problem.

Ps. Her laptop is more than powerful enough to run this game and her setting for the game are set really low.

Thank you.

Ohh i'm not sure if this has been writen about but i heard for more than 1 other player that sometimes my keyboard locks up while playing ether proventing me from moving or puts me in an auto-run in one direction.

You didn't mention whether the laptop was hardwired to the router or was using wireless. I could use my wireless perfectly for browsing, file download, etc, but whenever I tried playing wow it would either freeze or BSOD. When hardwired, it ran wow perfectly.
