I recently purchased an ASUS PCE-AC51 Wireless PCI-E Adapter for my PC and didn't have any driver problems on my Windows 10 (works as expected).
If I try to use it on my Linux (Fedora 26; 4.13.5-200.fc26.x86_64; GNOME 3.24.2) I have a tremendous performance drop. My connection is never faster than 100 Kb/s and it is simply useless.
The driver from the official ASUS website is out dated and I was not able to compile/install it.
I have tried installing
rtl8821ae from here and succeeded, but still performance is not improving.
Here are some more info:

Does anyone know what could be the cause of the issue I am dealing with?
PS. If I connect with LAN cable it works also as expected.
