DKMS Error [SOLVED]

Hi,

I updated by system to 6.13.1 and my WiFi has gone dead. I tried installing it by following instruction from https://github.com/nlkguy/archer-t2u-pl … me-ov-file

But when I do the last command "sudo make dkms_install", I get the following:

grep: warning: stray \ before #
grep: warning: stray \ before #

Re: DKMS Error [SOLVED]

What happens if you don't follow those instructions and perhaps use the package listed in the aur: https://aur.archlinux.org/packages/rtl8812au-dkms-git

Re: DKMS Error [SOLVED]

there's also this one with the aircrack-ng kernel module: https://aur.archlinux.org/packages/rtl8 … k-dkms-git

Re: DKMS Error [SOLVED]

rtl8812au-dkms-git won't compile on 6.13 either.
You need rtw88-dkms-git.
Also RTL8812AU will be supported by in-kernel driver in 6.14 (actually the same rtw88)

Re: DKMS Error [SOLVED]

Hi,

I tried the aircrack-ng kernel module. It too showed a DKMS error (Error 2).  See the log at https://hastebin.com/share/rigojiroli.bash

lsusb -v lists the device. But, when i do "sudo modprobe 8812au", I get this:

 modprobe: FATAL: Module 8812au not found in directory /lib/modules/6.13.1-arch1-1 

When I run "pacman -Qs dkms", I get:

 local/dkms 3.1.5-1
    Dynamic Kernel Modules System
local/rtl88xxau-aircrack-dkms-git r1299.337d3d6-1
    Aircrack-ng kernel module for Realtek 88XXau (USB adapters only) network cards
    (8811au, 8812au and 8821au chipsets) with monitor mode and injection support 

uname -a gives:

 Linux archy 6.13.1-arch1-1 #1 SMP PREEMPT_DYNAMIC Sun, 02 Feb 2025 01:02:29 +0000 x86_64 GNU/Linux 

while
pacman -Q linux gives:

 linux 6.13.1.arch1-1 

Am I doing something wrong? Thank you.

Re: DKMS Error [SOLVED]

Neither aircrack-ng not morrownr's rtl8812au driver will compile past 6.12 kernel.
Further support for most of Realtek's wireless chipsets goes to in-kernel rtw88 driver.
RTL8812AU is supported by rtw88 since kernel 6.13, but most of vendor specific usb ids are merged only in kernel 6.14.
So, for now this in-kernel driver is almost useless for most of RTL8812AU based devices (and RTL8821AU too).
But you can install rtw88-dkms-git from AUR, it's the same code that will be in kernel 6.14.

Re: DKMS Error [SOLVED]

Thank you ImmortAlex, rtw88-dkms-git got installed and I have access to network.
