ieee802.11acを無効にしたい

AP機器(Linux）で無効

hostapd.confにて、ieee80211ac=0にする

STA機器(Linux)で無効

11ac無効（ACの2.4GHzと5GHzをOFF)

$ mlanutl wlan0 bandcfg 0x1f

参考文献「README_MLAN」より、0x1fでAC 2.4GとAC5Gを無効にした。

bandcfg
	This command is used to set/get infra/ad-hoc band.
	Note: This command is only available in disconnected state.

	Usage:
		mlanutl mlanX bandcfg [l] [m] [n]

	where the parameters:
		[l]: Infrastructure band
		     bit 0: B
		     bit 1: G
		     bit 2: A
		     bit 3: GN
		     bit 4: AN

		     bit 5: AC 2.4G
		     bit 6: AC 5G
		[m]: Ad-hoc start band
		     bit 0: B
		     bit 1: G
		     bit 2: A
		[n]: Ad-hoc start channel
	Examples:
		mlanutl mlan0 bandcfg            : Get infra/ad-hoc band and ad-hoc
		                                  start channel configurations
		mlanutl mlan0 bandcfg 1          : Set infra band to B only
		mlanutl mlan0 bandcfg 3 2 6      : Set infra band to B/G, ad-hoc start band
		                                  to G and ad-hoc start channel to 6
