My wifi adapter doesn't work [SOLVED]

My wifi adapter doesn't work I am not sure if it is the version of linux that made it obsolete or is it because I need to update it or download some file separately so the problem goes as follows

Re: My wifi adapter doesn't work [SOLVED]

What package are you using to provide rtl8821cu?  What version is it?  Which one of 8821au rtl88x2bu rtl8821cu is your wireless card using?

Re: My wifi adapter doesn't work [SOLVED]

I think it is the cu since others are updated except for cu and even if the others are updated it doesn't want to connect to the wifi

There are three packages for 8821cu in the AUR https://aur.archlinux.org/packages?O=0&K=8821cu are you using one of those?  If so which one and what is the installed version of that package?
Edit:

pacman -Qs 8821

Re: My wifi adapter doesn't work [SOLVED]

It shows the available wifi connections but when trying to connect it doesn't
I installed cu au
rtl8821au-dkms-git 5.12.5.2.r178.g45366a3-1
rtl8821cu-morrownr-dkms-git 5.12.0.4.128.589ec21-1

Re: My wifi adapter doesn't work [SOLVED]

I would suggest removing rtl8821au-dkms-git if the NIC does not use it and updating rtl8821cu-morrownr-dkms-git to the current version 5.12.0.4.145.80781de-1

It should ideally build without errors after explicitly updating it, does it not?

Re: My wifi adapter doesn't work [SOLVED]

rtl8821cu-morrownr-dkms-git  5.12.0.4.145.80781de-1 builds for 6.2.7-arch1-1 at least on my system so the issue should be resolved.  You may need to manually load the 8821cu module unless you reboot.
I would also suggest removing whatever provides the rtl88x2bu module if the NIC is not using it.

Re: My wifi adapter doesn't work [SOLVED]

yay -S rtl8821cu-morrownr-dkms-git

Re: My wifi adapter doesn't work [SOLVED]

it will generally automatically update to the latest version since it's a git package, you can look at the installed version with

pacman -Q rtl8821cu-morrownr-dkms-git

I used makepkg -Codd to clean the source directory and stop makepkg after extracting the source and ignore dependencies as I was not going to build the package this time.

Re: My wifi adapter doesn't work [SOLVED]

I think I should have upgraded it before updating my distro and now it don't connect to the wifi

How can I downgrade my distro version to the previous one?

Re: My wifi adapter doesn't work [SOLVED]

You can't, arch is rolling release.
You can downgrade the kernel, https://wiki.archlinux.org/title/Downgrading_packages - you need to have the old packages in your cache, though. Or network access.
But the whole point about dkms is that the relevant modules are compiled for whatever kernel you've installed.

Also, again: https://bbs.archlinux.org/viewtopic.php … 5#p2091625
