Asus USB Wifi

For Arch-based distributions (Arch, Manjaro, EnOS, Garuda)

The wifi chip in ASUS USB N10 Nano (B1) is Realtek 8188EUS1 and it works on Linux 5.9, but not Linux 5.10 or later.

Manjaro Wifi driver install

Both kernel header files and dkms are required to install DKMS drivers2:

1
2
3
sudo pacman -S $(pacman -Qsq "^linux" | grep "^linux[0-9]*[-rt]*$" | awk '{print $1"-headers"}' ORS=' ')

sudo pacman -S bc dkms git base-devel

Install the driver from AUR

1
paru -S 8188eu-dkms

After installation:

1
2
3
4
5
6
7
# Block the default kernel module to use the new driver. This step is optional because the AUR package should do this for you.
echo 'blacklist 8188eu' | sudo tee /etc/modprobe.d/8188eu-blacklist.conf

sudo depmod -a
sudo mkinitcpio -P

sudo reboot

If your WiFi is still not working properly, continue with the following steps3:

  1. Stop Network Manager
    1
    
    sudo systemctl stop NetworkManager
    
  2. Load your module into the kernel
    1
    
    MODULE=$(hwinfo --wlan | grep "Driver Activation Cmd" | cut -d " " -f9 | tr -d '"') && sudo modprobe $MODULE
    
  3. Raise your Device (WiFi adapter)
    1
    
    DEVICE=$(hwinfo --wlan | grep "Device File" | cut -d " " -f5) && sudo ip link set $DEVICE up
    
  4. Ensure all network adapters are unblocked:
    1
    
    sudo rfkill unblock all
    
  5. Then restart network manager:
    1
    
    sudo systemctl start NetworkManager
    

You may try serveral things to increase your success rate:

  • Fully shutdonw your computer, including unplug it for a while.
  • Plug the WiFi dongle back into a different USB port.
  • Boot into BIOS and disable any wired NIC, or reses to default settings.
  • Use another working kernel. (I ended up this this solution)
