Bonjour à vous, Je tourne en rond depuis hier soir suite à installation d’une carte wifi pci-e Asus PCE-AC66 (chipset BCM4360) Le pc est « utilisable » mais toute les 2 ou 3 secondes, il se fige pendant ce même temps. Le driver installé est « wl », « modprobe -r wl » me permet de reprendre la main complètement. Le wifi est fonctionnel et connecté à ma Livebox (sagem v2) en wpa mixed ; j’entend par fonctionnel qu’il n’y a pas de perte du réseau mais la vitesse est quasi nulle.
Matériellement, c’est une carte mère gigabyte (945GCMX/ICH7) + cpu core2duo , le bios est à jour, la rev pci-e est 1.1 et la carte est enfichée dans un slot 4x. Lors du POST, l’IRQ assignée automatiquement est la 10 et dans la première commande ci-dessous elle est à 16 Je joint quelques renseignements, si besoin de plus d’info ou commandes à effectuer, pas de soucis. Cordialement, Christophe De Natale ------------------ sudo lspci -vvnn 01:00.0 Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 02) Subsystem: ASUSTeK Computer Inc.
