Note when using WiFi adapters:

  • If you experience connection loss and reconnect this may be due that your mobile device tries to automatically switch to another WiFi since it detects that adapter WiFi has no Internet connectivity. This automatic switch can be disabled from device settings. The location of the setting varies between OS version and device.
