Q. Why is the radio signal quality black (zero) in my wireless client?

Radio signal quality is black (zero)

Please read the following possible causes and check them step by step:

1. The NIC has not been initialed. ( Please check it in Windows Device Manager's Adapter Property. )

2. The ESSID of all wireless devices are not the same one.

3. The ESSID of all wireless devices are the same one, but the lower case/upper case of all domain name are not the same completely. For example, one domain name is set to be 'Default', but another is set to be 'default'. That is not correct.

4. The distance between two wireless stations (Ad Hoc mode) or between the wireless station and the AP ( Infrastructure mode ) is too far.

5. Make sure there is no any wireless interference (from other 2.4 GHz devices) around your DrayTek wireless station and the router.
