Hello,

I have a Powerline Wifi Extender 4220 to which I am perfectly able to connect. I do a speed test, I get nice down/up speeds as well as a low ping. Everything works fine except for the moment when I go play some online games (tried several and with different computers) where the lag makes it impossible to play. I can't connect by ethernet, I can't get closer to the device (I'm next room anyway). I have tried to touch plenty of ipconfig parameters on windows command prompt, changing DNS, used static ip's... everything you can find when you google the issue I've already done it.

Thanks!
