Chapter 6 Troubleshooting Page 63

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);

•

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
