I've installed Garuda Linux on my machine and upgraded the system. However, after I reboot, I face a wifi connection problem : the network manager cannot detect my wifi router but only detects my phone if I set it as a mobile hotspot. I've been searching a lot for a fix to this issue and I even reinstalled Garuda so many times but after I reboot I come to face that annoying problem again.

I've tried many solutions provided for such a problem in various websites and forums and none of them did work :

  1. restarting the network manager with sudo systemctl restart NetworkManager
  2. disabling wifi powersave
  3. adding 2 lines as following to /etc/NetworkManager/NetworkManager.conf:
[device]
wifi.scan-rand-mac-address=no
  1. adding 2 lines as following to /etc/NetworkManager/conf.d/nm.conf :
[device]
wifi.backend=iwd

and I ran these commands :

sudo pacman -S iwd
sudo systemctl stop wpa_supplicant
sudo systemctl mask wpa_supplicant
sudo systemctl enable --now iwd.service
sudo systemctl daemon-reload
sudo systemctl start iwd.service
  1. I also restarted my wifi router in vain

So what shall I do now ?

NOTE :

Sometimes when trying some of the mentionned fixes, the network manager detects my wifi router but it cannot connect to it and shows : Authorization supplicant failed

  • If the authorization failed, you either typed the wrong password, or you ran into a "known-bug", to which the work-around seems to be to install `connman-git`. – Ljm Dullaart Feb 04 '22 at 10:05
  • @LjmDullaart the password is correct. But could you clarify the 2nd point ? – Salem Feb 04 '22 at 16:33

    As I understand, there is a bug in certain `connman` versions that make authentication a problem. Installing the `connman-git` seems to be a workaround. As I don't run Garuda myself, I jus passed the info in the comments. – Ljm Dullaart Feb 06 '22 at 21:21
  • @LjmDullaart I'm not using connman but instead the Garuda network manager. – Salem Feb 24 '22 at 17:35
