Iv'e been having the same occuring problem for the past while and my isp is clueless as to what is going on, so i have decided to take it into my own hands and sign up on some forums and search for an answer.
So lately i have been getting 30-50 extra ping in all online games and its quite annoying especially in FPs games. My isp just keeps telling me online games raise your ping or something along those lines cause its my fault and not theres apparently. My specs are
Processor : AMD Phenom™ II X2 555 3.20ghz
2gbs of ram
32bit vista home premium.
If im missing any important info let me know
any help is very appreciated
( I live very close to toronto)
