General Questions
Review these topics for answers to general questions about the mobile hotspot.
Why isn't my battery charging?
If you are in a low-coverage area, are transferring a lot of data, or left the mobile hotspot
in a hot location, the internal temperature of the mobile hotspot can rise above 45°C.
In these conditions, the battery cannot be charged due to safety limits with lithium-ion
battery technology.
Check to ensure that the USB cable and the AC wall charger are connected securely
and are working correctly.
If the device is left charging for over seven consecutive days, the device automatically
enters a battery longevity mode to enhance the life of the battery. During this state, the
device stops charging and allows the battery level to drop to and maintain at
approximately 75 percent. The next time the device is plugged into a charger, it resumes
charging.
Why is the Signal Strength indicator always low?
Your mobile hotspot's reception is poor. Try moving it to a location with a clear view of
the sky (for example, near a window).
Why is the download or upload speed slow?
Data transfer speed depends on signal strength and interfering radio sources like
electrical generators or other mobile hotspot Wi-Fi devices. Review the following
possibilities:
• Check your signal strength and network type (for example, LTE 4G is generally faster
than 3G).
• Check Wi-Fi interference by powering the mobile hotspot off and on to find a better
Wi-Fi channel.
• Change the Wi-Fi band from 2.4 GHz to 5 GHz.
• If the network signal is low, consider using external antennas or cradle the mobile
hotspot with built-in high-gain antennas.
