Hi @SRK,
Welcome to the forum, the linux 64 bit driver is available in the Assus support webpage.
‘https://www.asus.com/us/Networking/USBAC56/HelpDesk_Download’
It is a rtl8812 (Realtek), you also can found the drivers in this link:
‘https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/log/?qt=grep&q=rtl8812ae’
The post in the forum at which I found this link is
‘Can't install manjaro, rtl8812 network card not recognized’
Hope it help, regards
