Hi! I'm trying to use hostapd with automatic channel selection on a 5 GHz mt76 radio. There are no other networks in my environment, so there are also no scan results returned from the driver. I'd be glad to know if this is actually supposed to work or known not to work. Calling hostapd looks like this: Configuration file: /var/run/hostapd-phy0.conf wlan0: interface state UNINITIALIZED->COUNTRY_UPDATE ACS: Automatic channel selection started, this may take a bit wlan0: interface state COUNTRY_UPDATE->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 nl80211: deinit ifname=wlan0 disabled_11b_rates=0 wlan0: interface state DISABLED->DISABLED wlan0: interface state DISABLED->DISABLED wlan0: AP-DISABLED hostapd_free_hapd_data: Interface wlan0 wasn't started hostapd.conf looks like this: driver=nl80211 logger_syslog=127 logger_syslog_level=2 logger_stdout=127 logger_stdout_level=2 country_code=DE ieee80211d=1 ieee80211h=1 hw_mode=a channel=acs_survey ieee80211n=1 ht_coex=0 ht_capab=[HT40+][LDPC][SHORT-GI-20][SHORT-GI-40][TX-STBC][RX-STBC1] vht_oper_chwidth=1 vht_oper_centr_freq_seg0_idx=-6 ieee80211ac=1 vht_capab=[RXLDPC][SHORT-GI-80][TX-STBC-2BY1][RX-STBC-1][MAX-A-MPDU-LEN-EXP0] interface=wlan0 ctrl_interface=/var/run/hostapd ap_isolate=1 disassoc_low_ack=1 preamble=1 wmm_enabled=1 ignore_broadcast_ssid=0 uapsd_advertisement_enabled=1 wpa_passphrase=topsecretpassword auth_algs=1 wpa=2 wpa_pairwise=CCMP ssid=OpenWrt bridge=br-lan wpa_key_mgmt=WPA-PSK okc=0 disable_pmksa_caching=1 bssid=78:a3:51:0d:12:f5 Cheers Daniel _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
