WiFi adapter not recognized

heyho. as the title states:

installed manjaro today for the first time next to win10 and manjaro doesn’t recognize the WiFi adapter. WiFi works on win10.

found a similar thread with a broadcomm board, but not for realtek. Also, it doesn’t even state the 2nd device properly

and is fast startup disabled in windows?
is fast boot disabled in bios - you may not have this option

fast boot in win10 is off. bios does not have a fast boot option. secure boot is off

5.15.74-3-MANJARO (linux515)
The following kernels are installed in your system:
   * linux515

so install kernel headers:
pamac install linux515-headers
install the driver, this one should be it:
pamac build rtl8852be-dkms-git
reboot and see if it helped

worked like a charm. thank you so very much!

side-question: whenever i shut down manjaro, i get a mainboard “beep” like I’m entering the bios. i dont have that with win10. could you by chance shine light on that?

you can disable the module that causes the beep:

sudo tee /etc/modprobe.d/nobeep.conf <<< 'blacklist pcspkr'

then run this:
sudo mkinitcpio -P
reboot to apply the blacklist;
it should be disabled by the next reboot or shutdown

mhwd-kernel -li output:

6.0.8-1-MANJARO (linux60)
The following kernels are installed in your system:
   * linux60

I tried the same steps as suggested here but my wifi is not working :frowning:

I would be very happy if someone can help me

did you installed the kernel headers for the linux60?
if yes, maybe the rtl8852be-dkms-git doesnt work with the linux60; so uninstall it and install this:
pamac build rtw8852be-dkms-git
reboot and test

Yes, I installed the headers for linux60.

I tried to install pamac build rtw8852be-dkms-git after uninstalling rtl8852be-dkms-gitbut this crashed while installing multiple times.

so install the 5.15 kernel + headers;
remove the rtw8852be-dkms-git
and install this again:
pamac build rtl8852be-dkms-git
reboot and in grub menu select the 5.15 kernel and see if that helped

Sadly this didn’t help :frowning:

The same as before:
