BF2 issues

[BrokenWall]

i got back into bf2 and installed it with the lastest update on both of my computers and now my other pc has no issues, but when i am playing i will randomly jump to a 250 ping and lag out why my buddy is playing fine on my other computer. and this lag is causing me not to be able to aim and walk, i will be aim at someone and i will hit a 250 ping next thing i know i am in front of him looking at the ground getting knifed.


its just so much pissing me off, what fixes are there for this.
