Briefly edit /etc/init.d/quantenna and add before $QCS_CALL rfenable 1
### CONFIG
$QCS_CALL set_ssid wifi0 Openwrt5G
$QCS_CALL set_WPA_encryption_modes wifi0 AESEncryption
$QCS_CALL set_WPA_authentication_mode wifi0 PSKAuthentication
$QCS_CALL set_passphrase wifi0 SecretH500 0
`
Sure there will be a better way to do with config file...
