[SOLVED] No WiFi option in arch

I was distrohopping for a long tome now and finally got to try arch. I installed it with "archfi" and I have the same exact problem that I had with every single distro: No wifi option in the settings, therefore no WiFi and no sound from built-in speakers (even if wireless earbuds work just fine). Those are both drivers problems, but I have never used pacman before so I dont know how to install them. The WiFi driver should be "rtl8821CU". This is the first time I am using arch or pacman so help would be really appretiated.

Re: [SOLVED] No WiFi option in arch

If you really have an rtl8821cu wifi device, then you can try the driver from the AUR:
https://aur.archlinux.org/packages/rtl8821cu-dkms-git/
https://wiki.archlinux.org/title/Arch_User_Repository

There is also this modification of an existing driver that might be added to the kernel some time in the future. (There is no PKGBUILD available, though.)
https://github.com/ulli-kroll/rtw88-usb

Debugging the wireless interface is best done from the commandline, though and not the GUI (Commands "ip ...", "iw ...", "dmesg", ...)

Oh, awesome. We get to play 20 questions? Does the name of the DE start with a G?

I have seen those already, but the problem is that I don't know how to install the drivers (what commands I have to run)

Sorry, I'm just very new to linux, there's no need to be mean. I'm running cinnamon. I need "rtl8821cu" driver. I don't know how to install it via the command line bacause I never used pacman before. what else do you need?

Re: [SOLVED] No WiFi option in arch

The second link in progandy's reply explains how the AUR works and how to install packages from it. It contains the commands to run and the prerequisites necessary for using it. The wiki is there so the basics don't have to be repeated time and time again. If you have trouble understanding a paragraph on the wiki, then point out where you are stuck.

Why do you want to use Arch Linux? It's not a good entry level distribution, and that leads to multiple levels of frustration, because you have a system that doesn't work like you expect it to, it leads to frustrations on our side because we expect a certain level of self sufficiency and a willingness to read the resources provided.

... and technically the archfi installer is completely unsupported here and you should ask the archfi author for help.

I have followed the instructions on the wiki and downloaded the package, now the wifi works perfectly. I still have a problem: I have no sound from the built-in speakers and I don't know what package I need for them, also in pulseaudio the only output option is "dummy output" (the same problem I had in every single distro)

Re: [SOLVED] No WiFi option in arch

Section 3 on the AUR wiki page should have the necessary steps:

3 Installing and upgrading packages
    3.1 Prerequisites
    3.2 Acquire build files
    3.3 Acquire a PGP public key if needed
    3.4 Build the package
    3.5 Install the package

For the build step 3.4 you are told more info is in the makepkg article, especially the Usage section.

Thank you very much. WiFi is working now) but I still have a problem: I have no sound from the built-in speakers and I don't know what package I need for them, also in pulseaudio the only output option is "dummy output" (the same problem I had in every single distro)
