for the last 2 months this game has become unplayable for me.

my ping while playing LOL ranges from 50 to 13000 (new high score).

then immediately I would run speedtest.net (when my ping is in the 1000-2000 range) i get a 47 ping reading.

sometimes speedtest does tell me i have 200-300 ping. but when i shutdown your client i get my normal ping levels( 100ish).

I already contacted my isp and they said they weren't able to identify the problem.

I know alot of people are having the same problem, can anyone suggest a fix or input in the matter?
