Bonjour tout le monde et mains secourables.
Après avoir modifié ma sécu wifi en Wpa2 et laissé la gestion du canal automatiquement à la box,
après avoir configuré mon regdomain en=FR sans réussir à éditer le fichier /etc/default/crda car sudo touch l'ouvre mais me le ferme aussitot.
Mon Wifi est toujours aussi lent et instable depuis installation de LUBUNTU 16.04 sur mon terra-mobile. Sous windows10 avant (sans regret). Je viens donc vers vous pour m'aider.
