Q 4. What if I can not open the Web-based management interface?
Please check the followings:
• Check whether the power supply is OK; Try to power on the unit again.
• Check whether the IP address of PC is correct (in the same network segment as the unit);
• Login the unit via other browser such as Firefox.
• Hard reset the unit.
Q 5. What if the signal quality is poor or not so good?
• Check whether there is obstacle between units. Obstacle may lead to poor signal.
• Check the antenna height. Place the unit in a high position can help to get a better
communication in long distance transmission.
• Check the polarization direction of antenna. Keep the polarization direction of antennas on 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 directional antenna. Big
angle shift may lead to poor signal.
• Check the feeder length. Too long feeder may increase the signal loss and affect the unit
performance
