FAQ and Troubleshooting
This chapter provides solutions to problems usually encountered
during the installation and operation of the B-400. Please refer to the
following descriptions, and for further assistance, please contact the
dealer.
Q: My PC can’t locate the Wireless Ethernet adapter.
How do I solve the problem?
A: Please follow the procedures below:
 Check if the Ethernet cable is well connected.
 Check if the IP addresses of the PC and B-400 Wireless
Ethernet adapter both are on the same IP network. If not, the
Wireless Navigator can be used to set up the adapter’s IP
address, or the PC’s IP address can be changed directly.
Q: The B-400 adapter cannot communicate with the
Wireless Access Point. How do I solve the problem?
A: Please follow the procedures below:
 Check if the Wireless Navigator utility is available to access the
B-400 first. If not, please go through the procedure of Q1.
 Check if the adapter is set to Infrastructure correctly.
 Check if the SSID of your adapter is the same as AP’s. If not,
please set it to the same SSID as the access point.

 Finally, please check if radio interference is causing a problem;
see if connection is possible when close to the Wireless
Access Point. The connection range can be as short as 100
feet in a poor environment.

400, and its antenna’s direction. If interference is the problem,
changing to another channel (1, 6 or 11) may improve the signal.

MAC or Linux PC, or if I do not have the Wireless
Navigator?
A: The default IP of the ZyAIR B-400 is 192.168.1.11. The web
configurator can be accessed through the web browser directly.
(Note: The host’s IP must be first configured to the same
subnet as the ZyAIR B-400).
