Garuda Linux : annoying network problem

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 ~~~ 4) 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 ~~~ 5) 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
