Ping suddenly increased after switching to w7 from XP

So when I do speedtest and select nearest host, I usually get 3 ping and (average) 75mbps. After installing windows 7, I recently found out that ping result always is 50, and
download speed capped to like 55mbps.

Also, I pinged a game I play with command prompt, I get about 165ms averagely on XP, and after Windows 7, it went up to 189-192.
