ROG G551JM WiFi etremely slow

Hello,

I just bought an Asus ROG G551JM-CN120H, but the WiFi is extremely slow.
I tried downloading google chrome and that took over 5 mins.
Opening this forum page took me a few minutes aswell.
I downloaded the latest Atheros wifi driver from the asus support site. (Yes I got an Atheros wifi chip according to system management)

I was downloading the latest nVidia driver with Geforce Experience and my download speed was between 10-80 kpbs

What can I do to improve this?
