I just can't wrap my head around this one.
My brother is playing League of Legends, has 99 ping. I plug in my laptop, his ping immediately spikes to 1k then eventually hovers between 200-300ms.
At the same time, my download speed drops from 1.50 MBps to 40KBps.
Everything goes back to normal after I unplug it.
