Q 4. What if I can not open the Web-based management interface?
Please check the followings:
 Check if the power supply is OK; Try to power on the unit again.
 Check if the IP address of PC is correct (in the same network segment as the unit);
 Log into the unit via other browsers such as Firefox.
 Hard reset the unit.
Q 5. What if the signal quality is poor or not so good?
 Check if there is an obstacle between units. An obstacle may result in a weak receive signal
level.
 Check the antenna height. Place the unit in a high position can help to get a better
communication for long distance transmission.
 Check the polarization direction of antenna. Keep the polarization direction of antennas for two
associating units the same; if not (one is horizontal, another is vertical), the signal quality may
reduce dramatically.
 Check the antenna angle. Align the antenna to the remote one if using a directional antenna.
A large angle shift may lead to a poor signal.
 Check the feeder length. Too long a feeder may increase the signal loss and affect the unit‟s
performance.
