Problema con driver scheda wi-fi rtl8821ce

Vi allego una piccola parte del log di network-manager riferita ad un fallimento della connessione:

   device (wlo1): Activation: (wifi) connection 'sebwifi' has security, and secrets exist.  No new secrets needed.
     Config: added 'ssid' value 'sebwifi'
     Config: added 'scan_ssid' value '1'
     Config: added 'bgscan' value 'simple:30:-80:86400'
     Config: added 'key_mgmt' value 'WPA-PSK'
     Config: added 'auth_alg' value 'OPEN'
     Config: added 'psk' value '<hidden>'
     device (wlo1): supplicant interface state: disconnected -> scanning

Ha funzionato !! Ho disinstallato il modulo, cambiata la stringa che mi hai indicato nel MakeFile e ricompilato, ed adesso va tutto alla grande !! Grazie mille davvero sarcade per l'impegno nel risolvere il mio problema !!
