[CONF] enable 802.11AC in hostapd

[Alexandre Epert]

Hi,

I need to have a RTL8812AU based wifi usb dongle ( an Edimax AC600) to work in 802.11AC mode.

I can make it work on 2,4GHz band without problem (b, g or n) and on 5GHz only in "a" mode.

I was using hostpad form debian repository and I thought it may be old or uncompatible. I know some usb dongle require a particular hostapd from Realtek. I've compiled latest version from git with "CONFIG_IEEE80211AC=y" in .config file.

Problem is the same, it keeps telling me I'm in 802.11b mode and channel is not avaiiable:

-> /usr/local/bin//hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd1.conf
wlan1: interface state UNINITIALIZED->COUNTRY_UPDATE
wlan1: IEEE 802.11 Configured channel (36) not found from the channel list of current mode (0) IEEE 802.11b
wlan1: IEEE 802.11 Hardware does not support configured channel
Could not select hw_mode and channel. (-3)
wlan1: interface state COUNTRY_UPDATE->DISABLED
wlan1: AP-DISABLED
wlan1: Unable to setup interface.
wlan1: interface state DISABLED->DISABLED
wlan1: AP-DISABLED
hostapd_free_hapd_data: Interface wlan1 wasn't started
nl80211: deinit ifname=wlan1 disabled_11b_rates=0

-> hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd1.conf
wlan1: interface state UNINITIALIZED->COUNTRY_UPDATE
wlan1: IEEE 802.11 Configured channel (36) not found from the channel list of current mode (0) IEEE 802.11b
wlan1: IEEE 802.11 Hardware does not support configured channel

wlan1: interface state DISABLED->DISABLED
wlan1: AP-DISABLED
hostapd_free_hapd_data: Interface wlan1 wasn't started
nl80211: deinit ifname=wlan1 disabled_11b_rates=0


I'm sure I miss something but I can't tell what it is and I really have to make it work.

I hope someone here can help me.


Here is my hostapd.conf file :

interface=wlan1
bridge=br0
#hw_mode=a
channel=36
ieee80211d=1
country_code=FR
#ieee80211n=1
ieee80211ac=1
wmm_enabled=1
ignore_broadcast_ssid=0
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=IciWifi Embarque
