Salut,
Merci pour vos réponses.
Ci-dessous la .log de wificheck.
Ma clé wifi est : "Bus 001 Device 006: ID 07d1:3c07 D-Link System DWA-110 Wireless G Adapter(rev.A1) [Ralink RT2571W]"
Ça, c'est sûrement ma carte wifi intégrée (qui n'a jamais marché, d'où le dongle) : "Bus 001 Device 003: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller"
Et ça, mon téléphone pour vous répondre en 4G : "Bus 002 Device 003: ID 04e8:6863 Samsung Electronics Co., Ltd GT-I9500 [Galaxy S4] / GT-I9250 [Galaxy Nexus] (network tethering)"
Sinon, Christophe, la recherche Kernel + Driver ne donne rien d'intéressant :
