Bonjour,
Suite à une mise à jour récente, ma carte wifi PCI a cessé d'être prise en compte.
Elle est bien détectée par la commande "lspci | grep -i net" qui répond "04:00.0 Network controller: Ralink corp. RT2790 Wireless 802.11n 1T/2R PCIe".
Mais pas de possibilité de connexion Wifi par Network-Manager.
Voici le retour de WIFICHECK, la carte est déclarée "*-network NON-RÉCLAMÉ", ça veut dire quoi? Et surtout comment régler le problème?
Merci

A noter que la carte continue de fonctionner sous Win 10, puisque le PC est en dual-boot...
RESOLU :
Une histoire de noyaux ubuntu qui ne se mettait pas à jour. Solution -> Nouvelle install propre et le kernel rt2800 qui controle la carte est rétabli.
