WIFI PCI express card driver install error

Support Network
1

So I recently bought an Archer T4E AC1300 WIFI PCIE card because i wanted to switch from a USB wifi stick.

I searched for drivers and I found this site: TP-LINK Archer T4U - DeviWiki (ex WikiDevi)

In theory the chip inside the E and U versions are the same so I tried downloading the driver for it because the card will not work without the drivers.

When I tried to build the package with te make command I got the following error: make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/5.10.15-1-MANJARO/build M=/home/lukacs/driver/EW-7811UTC_UAC_DAC_USC_Linux_Driver_1.0.2.4/rtl8821AU_WiFi_linux_v5.3.4_28226.20180614_COEX20171103-6c6d modules

What should I do to properly install this driver.
My kernel version is: 5.10.15-1-MANJARO

It’ll be easier to build the driver from the AUR:

pamac build rtl8822bu

Just an fyi, you should wrap your output with ``` before and after the output to make it easier to read :slight_smile:
