i am struggling for a week to connect via NM together with

wpa_supplicant with dbus support. Before that i tried to use only
NM, but the nmcli was saying that the wlan0 interface was
unavailable. I was unable even to scan network using nmcli, but
iwlist wlan0 scan command was working just great. More over if i use
only wpa_supplicant configuration file with this command:

There is one more thing. This rtl8192fs driver needs private
parameters to work. Before i call wpa_supplicant command i need to
call this 4 commands:

But the connection isn't being established. I have attached logs
from wpa_supplicant and NetworkManager.

Btw. i have also tried to establish connection setting this iwpriv
parameters on wlan0 interface but for some reason these are not
working for wpa_supplicant/NetworkManager. 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.
