Package: firmware-iwlwifi Version: 20151018-2 This version is advertised as be necessary for kernels 4.2+ (whereas http://www.intel.com/support/fr/wireless/wlan/sb/cs-034398.htm lists already-included 3160-14 to be targeted to 4.2+) It is necessary for and does work for me with 4.3-rc7. https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi
