QUESTION:

The NDC wireless network is often interrupted. The NDC Lamp icon shows Red sometimes, or the Link Quality indicator of NDC Utility shows black.

ANSWER:

1. Please move your wireless PC closer to the Access Point to find a better signal.
If the signal is still weak, please change the angle of the antenna.

2. There may be interference, possibly caused by a microwave oven, 2.4GHz wireless phone, or metal objects (e.g. file cabinets, metal cubicles, metal ceiling). Please move these interference sources or change the location of the wireless PC or AP.

3. Please change the wireless channel on the AP.
In a multiple cell network topology, overlapping or adjacent cells using different channels can operate simultaneously without interference if the frequency distance between the center frequencies is at least 30MHz. For example channels 1, 7 and 11 are non-overlapping frequency channels.

4. Please check the AP antenna, connectors, and cabling are firmly connected.
