Wifi qui saute

pierredek · Le 06/01/2021, à 00:24

bonjour à tous et toutes

j'ai 2 ordi (macbook pro 2009 et vaio avec dual boot) sous Ubuntu 20.04. quand je me connecte à mon répétiteur: pas de problemes. Par contre sur mon routeur (en wpa2) j'ai toutes les 5 minutes un popup "authentification necessaire". Pareil pour les deux ordi donc pas de probleme de driver
ipv4 & ipv6 automatique DHCP, securite WPA/WPA2 privees pour routeur et repetiteur

Une idée ? Merci
