I've installed FreeBSD CURRENT on laptop with Intel 7260 WiFi adapter. It works with `iwm` driver and appropriate firmware, but it could associate with AP only at 1M speed: # ifconfig wlan0 wlan0: flags=8843 metric 0 mtu 1500 ether 7c:7a:91:98:80:46 inet6 fe80::7e7a:91ff:fe98:8046%wlan0 prefixlen 64 scopeid 0x3 inet6 2001:470:923f:3:7e7a:91ff:fe98:8046 prefixlen 64 autoconf inet 192.168.136.129 netmask 0xffffff00 broadcast 192.168.136.255 groups: wlan ssid home.serebryakov.spb.ru channel 6 (2437 MHz 11g) bssid f0:9f:c2:f4:3d:b7 regdomain NONE country RU authmode WPA2/802.11i privacy ON deftxkey UNDEF AES-CCM 2:128-bit AES-CCM 3:128-bit txpower 30 bmiss 10 scanvalid 60 protmode CTS wme roaming MANUAL parent interface: iwm0 media: IEEE 802.11 Wireless Ethernet DS/1Mbps mode 11g status: associated nd6 options=23 # ifconfig wlan0 list sta ADDR AID CHAN RATE RSSI IDLE TXSEQ RXSEQ CAPS FLAG f0:9f:c2:f4:3d:b7 1 6 1M 44.0 0 44204 19328 EPS AQEU BSSLOAD HTCAP WME ATH RSN (rssi 0.0:0.0:0.0:0.0 nf 0:0:0:0) # Other devices (mobile phones, two laptops with Windows 10) connect with 802.11n speeds at same physical spot.
