I'm on a jessie on an embedded device, trying to set the WLAN into AP mode. When I try
# /usr/sbin/hostapd -P /run/hostapd.wlan0.pid /etc/hostapd/hostapd.conf Configuration file: /etc/hostapd/hostapd.conf ACS: Automatic channel selection started, this may take a bit wlan0: interface state UNINITIALIZED->ACS wlan0: ACS-STARTED ACS: Unable to collect survey data ACS: All study options have failed Interface initialization failed wlan0: interface state ACS->DISABLED wlan0: AP-DISABLED ACS: Possibly channel configuration is invalid, please report this along with your config file. ACS: Failed to start wlan0: AP-DISABLED hostapd_free_hapd_data: Interface wlan0 wasn't started wlan0: interface state DISABLED->DISABLED hostapd_free_hapd_data: Interface wlan0 wasn't started
My config file is:
# cat /etc/hostapd/hostapd.conf interface=wlan0 driver=nl80211 channel=acs hw_mode=g wmm_enabled=0 max_num_sta=1 ssid=foobarfoo
The error message can be found in a web search, but the solutions don't fit for me: I don't use ǹetwork-manager
driver works on a different device (handmade buildroot system) andhostapd
(not the buggyv2.1`)
Any idea how to narrow the problem further?
channel=1 it runs, so it's definately an acs problem, but what can I try to find out the root of the problem?
