If the LG smartphone is set up and used as a WLAN hotspot, the maximum connections can also be set.

For whatever reason, a password protected hotspot allows a maximum of 3 devices to connect to the LG smartphone, but if an open WLAN hotspot is set up, the connections can be limited between 1 and 10.
