How do I install driver for a RTL8812AU wifi USB adapter?

Rocky Linux Help & Support
1

I’m running Rocky Linux 8.10 (primarily for use with Davinci Resolve Studio, which is working great.) There’s no other OS on this i7-5820K CPU, 32GB RAM NVIDIA 980Ti 6GB VRAM GPU system.

The WiFi adapter is new and includes a CD containing the driver, but as I’m a Linux newbie, I don’t know how to install the driver. Looking at the CD’s contents, I see it contains 2 directories, one directory named “RTL8812BU_WiFi_linux” (containing “RTL88x2BU_WiFi_linux_v5.2.4.4_25643.20171212_COEX20171012-5044.zip”) and another directory named “RTL8811CU_WiFi_linux” (containing “RTL8811CU_8821CU_WiFi_linux_v5.2.5.3.zip”).

I’d greatly appreciate step-by-step instructions on how to use the above info to get my wifi working. I searched thru posts in this forum but didn’t find a solution. Thank you in advance.

The vendor emailed a link which downloaded a file named …

RTL8812BU-AC1200M.rar

… but without instructions explaining what to do with this file.

Meanwhile, I read info on this page …

… and tried following some of the instructions there, but a driver for the rtl8812au WiFi adapter doesn’t seem to be available via the links there – but I could be mistaken, because I don’t know what I’m doing.

Any help will be greatly appreciated!

Hi,

Please provide the out of lsusb

If the command fails please issue sudo dnf install usbutils

Then re-run the lsusb

The wifi adapter is …

Realtek Semiconductor Corp. RTL88x2bu [AC1200 Techkey]

… correct?

Thanks for your help! What do I do next?

Hi,

From a quick google search, it looks likes on rocky linux 10, the dongle is supported by the kernel. For 8 and 9 you’ll need to compile from source. Looks like this should work:-

Thanks for the link, Tom!

I downloaded the .ZIP file from the github page, and unzipped it. The github page instructions say …

In order to make direct use of the driver it should suffice to build the driver with make and to load it with insmod 88x2bu.ko

… but apparently I’m using the wrong syntax in the terminal, because I get ‘No such command: make’ errors, etc.

10

For example, I tried …

[pjd@localhost Downloads]$ sudo dnf make rtl88x2bu-5.8.7.1_35809.20191129_COEX20191120-7777
[sudo] password for pjd:
No such command: make. Please use /bin/dnf --help
It could be a DNF plugin command, try: “dnf install ‘dnf-command(make)’”

11

Hi,

dnf is not involved, as you are trying to install from source not a pre-compiled package.

I’m not in a position test but I think this should work:-

sudo dnf install kernel-devel kernel-headers gcc make dkms`
make

If it fails here, which it may do as there probably dependencies missing; please post the full error message.

If the make succeeds then continue you with:-

sudo ./deploy.sh
sudo modprobe cfg80211

Regards Tom.

Cool. When I type the following in terminal and press enter …

sudo dnf install kernel-devel kernel-headers gcc make dkms`

… all I see is “>” and nothing else seems to happen. If I then type “make” and press return, again I just see “>”. No errors, nothing.

13

Hi,

Can you provide a screenshot of this, please?

Regards Tom.

Sorry typo. remove the ' after dkms.

No worries about the typo. Some progress here, but then errors …

Hi,

Not sure whats going on. A google search suggests the driver won’t compile for a kernel versions older than 6, but repo reports support for older versions. You could raise an issue with the developer but they have marked driver as deprecate, so I’m not sure what response you will get.

Alternatively I have found this driver:-

If its going to work the instructions under “Using DKMS” should suffice.

Regards Tom.

Thanks Tom. Much appreciated. I’ll try that other driver and report results.

Hi,

It looks to be failing in the same place as the other driver. I’ve tried applying the patch from the this issue:-

Which gets further but still fails. I’d raise an issue with the developer, they seem quite active.

I’d include the link to the previous issue and your os and the kernel (uname -r), lsusb and the error:-

good luck with getting this resolved. I’m sorry I couldn’t be of any further assistance.
