Wifi not working on my MacBook Pro 2015 121

General system Newbie

Hi everyone, I’m new to EndeavourOS.

I’m trying to connect to Wi-Fi, but I get the following error when I run the command: `nmcli dev wifi connect NAME_WIFI password PASSWORD`.

Error: You need your password or encryption key to access the wireless network ‘NAME_WIFI’.

I’ve tried the suggested solutions, but none of them work.

thanks

Hi @eso

I installed a new EndeavourOS.

I logged into my account.

Here is the result of your command.

Have you tried adding the kernel parameter brcmfmac.feature_disable=0x82000

Side Note:I do not have such a Mac device
yay -S iwd

cat <<EOF | sudo tee /etc/NetworkManager/conf.d/wifi_backend.conf
[device]
wifi.backend=iwd
EOF

sudo systemctl restart NetworkManager

Yes, it works, thank you @ricklinux

And thx @eso

Troubleshooting steps:

  • Open the /etc/default/grub file with the command sudo nano /etc/default/grub (if you are using GRUB boot).

  • Add brcmfmac.feature_disable=0x82000 to the line GRUB_CMDLINE_LINUX_DEFAULT="…. brcmfmac.feature_disable=0x82000".

  • Regenerate the GRUB configuration with the command sudo grub-mkconfig -o /boot/grub/grub.cfg.

  • Then reboot. It should work :tada: .
