wifi désactivé cause inconnue...

Bonjour
Après une installation de la version

~$ uname -a
Linux tom-Aspire-ES1-523 5.8.0-43-generic #49~20.04.1-Ubuntu SMP Fri Feb 5 09:57:56 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

sans trop de problèmes...
ma connexion wifi a fonctionné un certain temps puis plus rien.
paramètres --> Wifi me répond "Aucun adaptateur wifi trouvé"
J'ai bien essayé de désactiver le secure-boot mais en vain
Quelques infos supplémentaires en vrac :

et aussi :

~$ nmcli dev  wifi

et enfin

~$ nmcli

Que signifie en particulier le "sw désactivé" ?
Une idée pour réactiver ce qui peut l'être ?
Cordialement
