Tips
When the Mobile WiFi is in use for an extended period of time, it will become warm and may
overheat. Should this happen, the Mobile WiFi will automatically close the network connection
and turn off to protect itself from damage. If this occurs, place the Mobile WiFi in a
well-ventilated space to allow the heat to dissipate, then turn it on and continue to use it as
normal.
If you are unable to use the Mobile WiFi as normal, try the following:
Consult the online help on the web management page.

Restart the Mobile WiFi.

Restore the Mobile WiFi to the factory settings.

Consult your operator.
