Windows 7 Slow Internet, Installed XP VM, Internet is fast, help?

[Xecuter]

I've noticed ever since I installed Windows 7 that my internet is way more slow and unstable.
I've tried turning my firewall off and everything I could think of that could be the problem, but nothing worked.

So I installed a WindowsXP VM...and what do you know, the internet on the VM is like 500% faster than on 7.

Any suggestions?
