bonjour j’ai une Debian stable (9.5) installée sur un disque externe USB3 que j’ai présenté à un portable Lenovo (A275). Nikel après avoir mis à jour les firmware (la Debian tournait avant sur un portable Dell). Le Wifi me résiste encore et toujours. lspci m’a appris que c’est un contrôleur Realtek B8822BE ```nohighlight D016955:~# lspci -k -nn |grep -i realtek -A 3 01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.

Aïe… D’habitude je reste plutôt sur du “stable”, voire “testing”. je n’ai donc pas l’habitude des rapports de bogues J’ai voulu explorer du “unstable”, bien mal m’en a pris. Je patienterai donc. merci!
