Re : Déconnexions permanentes du wifi 20.04 LTS
Bonjour,
Essaye un canal 6 au lieu du canal 11 > lafibre.info/wifi/quel-canal-wi-fi-choisir-pour-optimiser-son-debit
Conseils pour les nouveaux demandeurs et pas qu'eux
Important : Pensez à passer vos sujets en [Réso|u] lorsque ceux-ci le sont, au début du titre en cliquant sur Modifier sous le premier message, et un bref récapitulatif de la solution à la fin de celui-ci. Merci. Membre de Linux-Azur
