Ping issues with new computer - SAME INTERNET

Hi guys, I recently bought a new HP pavilion d76c23cl laptop computer. Upon downloading Crossfire, I jumped into a game and found that my ping was spiking like crazy. I've had another similar HP pavilion laptop, slightly older, that ran Crossfire perfectly fine. I would get a steady 85-95 ping without any noticeable problems with gameplay.

Now, my ping, when steady and normal, is around 86, the usual for me on the east coast servers(alpha, bravo, etc.) However, about every 3 seconds, my ping increases drastically to around 1.5k ping at the max. Other times, I'll just be jumped up to around 300-700 and it drops back down.

A side note, I'm using wireless internet...

What I've tried already:
Editing a registry value involving the Multimedia service - no luck
Overclocking my PC - Little luck, as it was 1.6 ghz before, it is now around 3 or so
Flushing my DNS with cmd - nothing
