Bonjour,

Je voudrais faire fonctionner ma carte wifi.
Voici le message

download the correct firmware for this driver version. Please
carefully read all instructions on this website.

Où les instructions ?

Une recherche me mène ici
https://wiki.debian.org/bcm43xx#b43-b43legacy
For devices with a BCM4312 LP-PHY chip (PCI ID 14E4:4315), install
firmware-b43-lpphy-installer:

Mais pas de version stable(jessie) ?

Quelqu'un a une idée ?

Merci d'avance.
