Now I'm using dlink DWA-548 desktop adapter but i experience a serious ping spikes which jump from 4-5 to 1900+ every 5-7 seconds. But when i try plug Ethernet and also use another laptop (wifi) do the ping test on cmd i see that don't have this problem. So i believe is my desktop adapter causing ping spikes.
Someone can help me solve it please.
