Let me put context, i have a router with DD-WRT, what i would like help with is that everytime someone starts watching youtube video or any online video content my online gaming well it lags or my pings just get very high.
I do have set up QoS, i do know i should use 85-90% of the real download/upload bandwith, i have added every phone, laptop, tablet and to my understanting it just does not work cause i always lag.
Maybe somebody has come across this and got a way to solve it!
