- NDC Communications Network Card User Manual

The WWB powers up,

but the Ethernet Link

LED is OFF (no

connection to an

Ethernet network).

Make sure:

1. The Ethernet cable is connected firmly to both the

WWB and Hub/Switch.

2. The Hub/Switch is powered on.

The Status LED on the

WWB panel is Red and

flashing.

Restart (power cycle) the WWB and check the Status

LED again. If it is still flashing, you need to return

the WWB to the reseller for repair.

Transmission

performance is slow or

erratic.

1. Move your WWB closer to the AP to find a better

signal. If the signal is still weak, change the

direction of the antenna slightly.

2. There may be interference, possibly caused by a

microwave oven, 2.4GHz wireless phone, or metal

objects. Move these interference sources or

change the location of the wireless PC or AP.

3. Change the wireless channel on the AP.

4. Check the WWB antenna, connectors, and cabling

are firmly connected

The AP and WWB are

working, but the PC

cannot connect to the

Ethernet network via the

AP.

1. The AP’s MAC access control function is enabled

and the WWB is denied access.

2. The Protocol Filter has blocked required protocols,

e.g. TCP/IP to the PC. Uncheck these protocols

from the filtering list. See Figure 16, page 34.

3. The IP settings on the PC are not correct.
