Vista Connection problem with WoW

I recently installed vista 64 bit on my computer and noticed the following problem.

When I'm downloading a file, watching youtube video or browsing forums with lots of pictures etc..it slows my connection down completly as if those are taking up all the bandwidth.

When I was using XP, it never had this problem. Only noticed it with Vista.

My system details;
Q6600 cpu
Vista 64bit
8 GB
ADSL2 internet connection.

I tried to look for similar topic couldn't find anything.

Anyone have similar problem?
