i have turned windows firewall off.
qgroundcontrol still no response

yes I restarted it

I can connect to the voxl ap and have entered the ip address in voxl-vision-px4.conf. When starting QGronudControl it does not see px4 service. QGroundControl will make a connection using the USB connection.
What am I missing?
