Bonjour xubu1957 ,
Merci pour ta réponse rapide.
J'ai vu le topic "rtl8187 la galere <resolu>" et réalisé le "troubleshoot" mais je n'a pas de problème d'applet network à priori.
J'ai passé le chiffrement de ma box de WPA-PSK [TKIP] + WPA2-PSK [AES] à WPA2-PSK [AES] pour essayer de résoudre le problème mais ça n'a rien changé.
Je fais les tests sur mon pc portable sous OpenSuse alors que mon "vieux pc" est sous Ubuntu 20, mais à priori le problème est similaire.
Voici les sorties des commandes indiquées :
lspci c'est pour la partie pci, ma carte wifi est en usb, mais voici la sortie :
lspci -nnk | grep 0280 -A3
00:14.3 Network controller [0280]: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 11)
Subsystem: Intel Corporation Device [8086:0030]
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
Au cas où ça aiderai, voici la sortie de la commande : sudo lsusb -v | grep -i realtek -A100
