Deauthenticated issue with AP

[Francisco Cuesta]

Hello,

I'm experiencing some issues with access point and wpa_supplicant. I'm
trying to set up an AP and and client, but I don't know why I cannot
connect them. I was looking into the log but there is nothing there
similar to an error neither with dmesg... What's more, if I type
wifi
command failed: Device or resource busy (-16)
Successfully initialized wpa_supplicant

I was prompted that output

Something more of info

root at router11:~# ps
...
10461 root      1392 S    wpa_supplicant -B -P /var/run/wifi-wlan1.pid
-D nl80211 -i wlan1 -c /var/run/wpa_supplicant-wlan1.conf

root at router11:~# cat /var/run/wpa_supplicant-wlan1.conf
ctrl_interface=/var/run/wpa_supplicant-wlan1

network={

    scan_ssid=1
    ssid="openWRT"
    bssid=XX:XX:XX:XX:XX:XX
    key_mgmt=NONE


    fixed_freq=1
}

Any hint would be appreciated!

Thanks in advance
