Can anybody help me? I have constant net jitter for a week. I updated my network drivers, I deinstalled and downloaded cs2 again, i called my internet provider, I changed my NAT-Type etc.

It has worked for me fine all the time and my ping is always at around 20 but I have now constant jitter at ~200ms with constant low ping

Thought I solved it by clearing my Cache because after that every Deathmatch went good without jitter, but played Premium with my friends today and it happened again.
