Hi eric3743, I understand what you are saying.
But i'm referring the Airties WIFI app not able to find the mesh network when the SSID is invisible.
Surfing internet or using other apps on the phone or tablet is not an issue. All are fine.
Just the Airties WIFI app not working,when SSID is invisible.
Once I turn either of the 2.4 or 5 GHz channel visible back on, it can work.
All phones & tablets do have already lock-in to the SSID upon activated as it is Auto detect and connect.
If you do Forget the SSID on the phone or tablet, then it will not be able to detect any hidden or invisible SSID.
Since Apps detection is based on active or live broadcast at the point you open the said App.
If the said SSID is hidden or invisible and so it will not be broadcast.
Therefore it will not be able to detect.
Unless you manually input the said SSID, then it will detect it.
Hence there is possible some do not like to broadcast their SSID for they may be afraid of being hacked or something.
There are plenty of other Apps to detect for wireless SSID.
Download these Apps to try and see it is the same or not.
