Since there is QOS feature in dd-wrt I would like to use it. My annoying brother always complains about his world of warcraft lagging, when we are surfing the net/streaming video/downloading etc etcâ€¦ How to configure it, for the best? Like warcraft always first priority. And then http traffic, and then all other to minimum. I have read something about the L7 filter, and its sounds great, but does it work at all?
