While in certain games on windows 7 ultimate my ping is very erratic, where it isnt in windows xp proExample: my clan server in counter strike source, i get a 20-25 ping on that server with windows xp, in windows 7 my ping with no downloading and no internet applications open is from 25-90 very quickly and very unstable. Since i know it's not my connection because it's fine using a different operating system i've been trying to find a solution. Any got any ideas?
