No Wifi Adapter

Trinadtsatiy · 2024-07-20 16:06:27

I have this problem about 2 days. I am using tethering to use the internet. But i have wifi adapter (USB!) and i want to use it with my Arch system.
So, what is the problem? Look here:

Artyom@cyberkernel ~> iwctl
NetworkConfigurationEnabled: disabled
StateDirectory: /var/lib/iwd
Version: 2.19
[iwd]# device list
Devices

[iwd]# station list

No devices in Station mode available.

Have you rebooted your device since?

Also which kernel package are you using? Does using linux-lts fix your issue?

Please also share the output of

lsusb

Yeah, i rebooted my system a lot of time
Kernel: Linux 6.9.10-arch1-1
You mean lsusb and lspci commands? Write a bit more about that

You can use any live ISO to run the `lsusb` command. It is available from the usbutils package if you can install that.

I found my wifi adapter. How i can activate it?

Head_on_a_Stick · 2024-07-21 10:15:41

Try https://aur.archlinux.org/packages/rtl8 … k-dkms-git.

Trinadtsatiy · 2024-07-21 10:48:14

What is that?

Head_on_a_Stick · 2024-07-21 10:51:12

An AUR package that provides a driver for the USB wifi card. To install it follow the instructions here.

gromit · 2024-07-21 10:52:22

Also did you already try the "linux-lts" package from the repos about which I asked earlier?

Hello again. Could you help me again. I dont understand what i am doing wrong. Dont be angry please. So what i did:
git clone https://aur.archlinux.org/rtl88xxau-air … ms-git.git
cd rtl*

What i need to do next?

Head_on_a_Stick · 2024-07-21 12:41:57

Firstly you need to pay attention to gromit's posts as well as mine — have you tried the LTS kernel version? Ignoring other users is a bit rude and in this case gromit is a member of the Arch development team so it is highly likely they know what they're talking about.

In respect of the AUR package, you need to read the PKGBUILD file to ensure it is not malicious and then use makepkg(8), as described in my wiki link. If you can't do that then perhaps try another distribution until you build up the requisite skills for Arch.

So, i just installed it and nothing happened. Am i doing something wrong?

gromit · 2024-07-21 13:57:34

You have to configure your bootloader to also find it and that depends a bit on the bootloader you're using I.e. for grub you'd have to go a "grub-mkconfig ..." and for systemd-boot you need to write the loader entry etc.

What bootloader are you using?

Thanks! I am using grub

gromit · 2024-07-21 19:51:33

Yeah then install the "linux-lts" package and run the configuration command specified here: https://wiki.archlinux.org/title/GRUB#G … ation_file

Then select the right kernel on boot and verify that you have indeed landed on it by checking the output of "uname -r" (which should mention -lts)

For reference https://github.com/aircrack-ng/rtl8812a … 532d8d3308 added 6.9 support to rtl88xxau-aircrack-dkms-git and I was able to build the module using 6.9.10.arch1-1 and 6.10.arch1-1.

https://bbs.archlinux.org/viewtopic.php?id=295816 went w/ https://github.com/morrownr/8821au-20210708 (but there seems no AUR package) and the OP will also need the linux-headers or linux-lts-headers.

loqs · 2024-07-21 22:37:39

Trinadtsatiy please post the outputs of the following commands in code tags:

pacman -Q  rtl88xxau-aircrack-dkms-git
pacman -Qs -- -headers
dkms status
uname -a
