Problème Wifi [résolu]
Bonjour,
je viens de faire un upgrade vers ubuntu 18.04 et depuis je n'arrive plus a me connecter au wifi de mon domicile.
ce qui est bizarre c'est je me connecte sans problème aux autres wifi.
J'ai essayé plusieurs solutions décrites dans les forums mais sans succès.
merci pour votre assistance.
BR
