My iwn device (iwn0: <Intel Centrino Advanced-N 6205>) supports 5 GHz. I just disabled my 2.4 GHz APs and reassociated: wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether <MY_ETHER> nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: IEEE 802.11 Wireless Ethernet MCS mode 11na status: associated ssid XXXXXXXX-5G channel 153 (5765 MHz 11a ht/40-) bssid <MY_BSSID> regdomain FCC country US authmode WPA2/802.11i privacy ON deftxkey UNDEF AES-CCM 2:128-bit txpower 23 bmiss 120 mcastrate 6 mgmtrate 6 scanvalid 16959 ampdulimit 64k ampdudensity 8 -amsdutx amsdurx shortgi -stbc -ldpc wme roaming MANUAL groups: wlan Some devices do and others don't. For example, I have an ath card for this same laptop (I swapped out my iwn card for an ath card for a short while) that supports station mode (BTW iwn firmware doesn't), discovering my ath device firmware does not support 5 GHz. I suspect that some iwn devices may be similarly "crippled", though the driver supports 5 GHz the firmware does not. My point is it's not a binary issue. You may need to Google your particular card to determine if the manufacturer has implemented the feature or not. I did for my ath card discovering not all implementations are equal. I wouldn't be surprised this might be true of iwn as well. -- Cheers, Cy Schubert <Cy.Schubert_at_cschubert.com> FreeBSD UNIX: <cy_at_FreeBSD.org> Web: http://www.FreeBSD.org The need of the many outweighs the greed of the few.Received on Sun Jun 03 2018 - 16:13:46 UTC
