I hope they make a fix for this problem, because it will chase people away from using Manjaro, Just saying.

Hi, glad you solved it. It is not a Manjaro problem, drivers for Network devices is a problem in a lot of distros(in my experience). I have Realtek, and i had problems with the drivers in Fedora, Ubuntu and Elementary OS. So, i think, is a common problem in Linux Distros.
