RTL88 Wifi Driver Isn't Working

Support Network
1

I bought a new 2 in 1 Wifi + Bluetooth Dongle. And I’ve tried everything to get wifi to function but it doesn’t work, Bluetooth works flawlessly. I previously had another wifi-only dongle, which worked fine when I installed Manjaro.

This is what I have tried yet:

  • Installed Kernal 4.19, 54, 5.15.
  • Installed/Uninstalled All Drivers which I found on Github & Aur
  • Try all answers with similar questions but still it doesn’t work.

Here : mhwd-kernel -li

Currently running: 5.15.71-1-MANJARO (linux515)
The following kernels are installed in your system:
   * linux419
   * linux515
   * linux54

try a newer kernel, for example the 5.19 (but not the ‘rt’ one, the normal one)

ok, let me try it.

I have tried it but it doesn’t work, it is the same.

Check this, it may help me,

Hi @adarshraj32, and welcome!

According to this page, the driver is included in kernel 4.1 and newer:

The device is supported by kernel versions 4.1 and newer according to the LKDDb

And, I see there is, indeed, a driver for this device in the AUR:

$ pamac search rtl8723au
rtl8723au_bt-dkms                                                                                                                                                                                                                                0.1-1  AUR
Bluetooth driver for RTL8723AE and RTL8723AU

But for dkms packages/drivers, you need the kernel headers. So first install your kernel(s) headers:

pamac install $(pamac list --installed --quiet | grep "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')

This will install the headers for all your installed kernels.

Then install the drivers:

pamac build rtl8723au_bt-dkms
