Bonjour, J'ai réinstallé mon portable lenovo Yoga 13 sous stretch et je rencontre des problèmes lors de la connexion WIFI
De base j'ai sous usb une puce RTL8723AU (Wifi+BT) qui est reconnue via lsusb et dans les messages de démarrage Bus 001 Device 004: ID 0bda:1724 Realtek Semiconductor Corp. RTL8723AU 802.11n WLAN Adapter May 21 23:38:57 yogayan kernel: [ 19.262374] usb 1-1.4: rtl8xxxu: Loading firmware rtlwifi/rtl8723aufw_B_NoBT.bin May 21 23:38:57 yogayan kernel: [ 19.267786] usb 1-1.4: firmware: direct-loading firmware rtlwifi/rtl8723aufw_B_NoBT.bin May 21 23:38:57 yogayan kernel: [ 19.267813] usb 1-1.4: Firmware revision 31.0 (signature 0x2302) en plus j'ai une clé DLink Bus 001 Device 010: ID 07d1:3c07 D-Link System DWA-110 Wireless G Adapter(rev.A1) [Ralink RT2571W] Dans les deux cas j'ai le même symptôme lors de la tentative de connexion en WIFI sur tous les ssid disponibles dans mon environnement : aborting authentication with 9a:a1:d7:52:c2:71 by local choice (Reason: 3=DEAUTH_LEAVING) Bien entendu "avant" le passage sous stretch, ce portable en Jessie fonctionnait en wifi sans problème... Mon ami google ne m'a pas été d'une grande aide sur ce point ou bien je n'ai pas su lui poser la question correctement... Merci d'avance pour vos remarques et suggestions... Yann.
