I am having an issue with diablo which has been going on for almost four months now im consistently have around 500-700 ms. My system does surpass the required for diablo does anyone have any idea why this may be?
ISP? Have you done a pathping/tracert?
I think I've had lag issues once in the last 6 months on Aus servers.
Havn't done that/ how do you do that
Download that, run it and use 126.96.36.199 as the host (Diablo's IP).
Let it run until after you experience your lag, post it here if you don't understand the results (there is a copy button in the program).
