Question Why does my mobile device sometimes disconnect from instrument WIFI?

Geometrics instruments, such as G-864, MagEx, MagArrow, MagStation et al, communicate with a mobile device via WIFI. But because the instrument WIFI has NO internet access, some Android device, after connecting to the instrument for a while, will automatically start searching for another WIFI access point. To prevent this from happening, when the No Internet Access warning window pops up after first WiFi connection, choose "Tap for options". On the following window, check the “Don’t ask again for this network” box and press “Yes” .
