Using NetworkManager on Arch Linux on a MacBookPro14,3, I am unable to connect to any wireless network. I've tried connecting to a number of different WiFi networks (home, mobile hotspot, work) all with the same result. I've tried doing this with both nmcli and nmtui. Example:

$ nmcli dev wifi connect <SSID> password <password>
Error: Connection activation failed: (7) Secrets were required, but not provided.

Looking at logs with journalctl shows:

wpa_supplicant[PID]: wlp3s0: CTRL-EVENT-ASSOC-REJECT bssid=00:00:00:00:00:00 status_code=16


NetworkManager[PID]: <info> [TIMESTAMP] device (wlp3s0): state change: need-auth -> failed (reason 'no-secrets', sys-iface-state: 'managed')

The Macbook has a Broadcom BCM43602 with driver brcmfmac. NetworkManager and wpa_supplicant are installed and enabled.


Try turn off and on Again the wifi like this:

nmcli r wifi off to turn off

nmcli r wifi on to turn on

Check the Wifi enables: nmcli d wifi list

Check and disconnect the wifi who appears green:

nmcli con to check

nmcli con down <wifi name> to disconnect

If you down know for sure if the password you put is right, do again the connection:

nmcli dev wifi con "wifi name" password "wifi password"

OBS: dont forget the "" on the name and the password

Or try to reconnect with the wifi: nmcli con up <wifi name>

Sometimes the problem is the connection with NetworkManager, if not working let me know!


Next solved my problem, was taken from: https://www.youtube.com/watch?v=P7bAp4vBxnA

  • Edit with sudo grants: /etc/NetworkManager/NetworkManager.conf

  • Add the next two lines:

  • Execute: sudo systemctl restart NetworkManager

  • Use your WiFi. ;)

  • I had the same problem again after the first valid connection with the above "solution". – Medardo Rodriguez May 18 at 15:41
