I was wondering if NM > somehow passes it's own configuration to the interface? If yes how > can make some modifications? Yes, NetworkManager passes its own configuration to wpa_supplicant via D-Bus. You should be able to see the configuration in NM logs; on my machine for example I see: NetworkManager[1645]: <info> [1611663864.0215] Config: added 'ssid' value 'home' NetworkManager[1645]: <info> [1611663864.0215] Config: added 'scan_ssid' value '1' NetworkManager[1645]: <info> [1611663864.0215] Config: added 'bgscan' value 'simple:30:-70:86400' NetworkManager[1645]: <info> [1611663864.0215] Config: added 'key_mgmt' value 'WPA-PSK WPA-PSK-SHA256 FT-PSK' NetworkManager[1645]: <info> [1611663864.0215] Config: added 'auth_alg' value 'OPEN' NetworkManager[1645]: <info> [1611663864.0215] Config: added 'psk' value '<hidden>' You could try to see if the same configuration works with wpa_supplicant alone. Regarding iwpriv parameters, NM doesn't support them. But if you set them manually before connecting with NM, I guess they should work. Beniamino
