WiFi hotspot problems at start
When you use they L5 as hotspot WiFi Access Point (for example for a laptop), the L5 is using data mobile to connect to Internet. Enabling is simple from Settings -> WiFi. This often results in a problem, that after a short moment (a few seconds) the hotspot disappears. Settings indicates then that there is no WLAN adapter. But you can enable the hotspot again, sometimes this has to be done two times, and then the hotspot works fine without any hick-up for hours.
