Using an external antenna (not included):

In areas with poor reception, connect an external antenna to the WiFi
Cube's external antenna port to improve signal strength.
Note:
Before connecting the external antenna, ensure that the WiFi Cube is

turned off and disconnected from the power outlet.
Make sure the antenna is approved for use with the WiFi Cube.

Only use the external antenna indoors, and do not use it during a

thunderstorm.
To optimize the external antenna performance place it at least 1 meter

away from the WiFi Cube. If you have installed two external antennas,
the distance between them must be greater than 1 meter.
