I did a bit more testing, I have to admit that I am not well versed in wifi internals. 1. ifconfig wlan0 list aps shows my aps having rate 54M (Im not entirely sure what this means). But however when I connect to it, it shows up as 11g wlan0: flags=8843 metric 0 mtu 1500 ether a4:4e:31:02:70:3c inet 192.168.23.111 netmask 0xffffff00 broadcast 192.168.23.255 nd6 options=29 media: IEEE 802.11 Wireless Ethernet MCS mode 11ng status: associated ssid LA03 channel 6 (2437 MHz 11g ht/20) bssid 52:d9:e7:47:c0:c2 regdomain FCC4 country DE authmode WPA2/802.11i privacy ON deftxkey UNDEF AES-CCM 2:128-bit txpower 30 bmiss 10 scanvalid 60 protmode CTS ampdulimit 64k ampdudensity 8 -amsdutx amsdurx shortgi -stbc -ldpc wme roaming MANUAL groups: wlan 2. Adding mode 11a to rc.conf didn't change anything. Still connects to 2.4Ghz band. 3. ifconfing wlan0 scan still doesn't show my 5Ghz only APs (at least some I tested) Also, what does 11a mean? shouldn't it be 11n? - dbalan
