My GF and I play with the same router, however she's using Wifi and I'm Wired.

I never got the problem on my Windows PC, but yesterday she constantly got kicked out to the main screen having to log again. She plays on a MAC air pro with a Windows 7 OEM installed. (yes it's dang slow, I see her jogging when she hits the sprint button lol)

Nevertheless, I got her a new HP Omen (she'll receive it in a few days.)

Still, hopefully up to this time, she won't get the same problems, cause the loading pages are freaking long when teleporting, and getting in the game.

Hope it will be addressed.
