Hello,
As I decided to try out the QoS which is embedded in DD-WRT (at least in the mega build) I applied these settings:
Then I went back in WoW and noticed this:
It was just my PC connected to it and nothing else (no downloads and etc.). Some might say just scrap the settings and go the old way but I kind of want to keep them since I`m not the only one using the network but still I want to prioritize my games before other stuff. Normally in 25 mans I get like 75ms to 120ms or something similar.
