You are very welcome, but don’t speak too soon, it’s not fixed yet.
And this may require more help than I have expertise for, especially for Gnome, since I use KDE.
One of the Antergos experts should be online soon, Dustin, and may have more answers.
And I see @pseudonym is online and has some answers for you too. I was also looking at the link he is recommending, but I couldn’t find the related info for ASUS.
Might need to look for Dustin as well.
edit: At second glance, since your network adapter is: Qualcomm Atheros AR9485 Wireless Network Adapter
that information on that link may help afterall.
As @pseudonym suggested, give it a try.
>>The difference would be ASUS instead of ACER:
[~]# sudo modprobe -r asus-wmi
[~]# sudo nano /etc/modprobe.d/ath9.conf
#Thereafter I just went ahead and added:
options ath9k nohwcrypt=1
