same wireless standard as the NBG6818.
• Make sure your computer (with a wireless adapter installed) is within the transmission range of the
NBG6818.
• Check that both the NBG6818 and the wireless adapter on your computer are using the same wireless
and wireless security settings.
• Make sure traffic between the WLAN and the LAN is not blocked by the firewall on the NBG6818.
• Make sure you allow the NBG6818 to be remotely accessed through the WLAN interface. Check your

I cannot access the Web Configurator after I switched to Bridge Mode.
• When you change from Standard Mode to Bridge Mode , your computer must have an IP address in
the range between “192.168.123.3” and “192.168.123.254”.
• Refer to Appendix B on page 153 for instructions on how to change your computer’s IP address.
What factors may cause intermittent or unstabled wireless connection? How can I solve this
problem?
The following factors may cause interference:
• Obstacles: walls, ceilings, furniture, and so on.
• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices.
To optimize the speed and quality of your wireless connection, you can:
• Move your wireless device closer to the AP if the signal strength is low.
• Reduce wireless interference that may be caused by other wireless networks or surrounding wireless
electronics such as cordless phones.
• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and
the wireless client.
• Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional
APs if necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless
client is sending or receiving a lot of information, it may have too many programs open that use the
Internet.
• Position the antennas for best reception. If the AP is placed on a table or floor, point the antennas
upwards. If the AP is placed at a high position, point the antennas downwards. Try pointing the
antennas in different directions and check which provides the strongest signal to the wireless clients.
