• Make sure the WiFi adapter installed on your computer is IEEE 802.11 compatible and supports the
same WiFi standard as the NBG7815.
• Make sure your computer (with a WiFi adapter installed) is within the transmission range of the
NBG7815.
• Check that both the NBG7815 and the WiFi adapter on your computer are using the same WiFi and
WiFi security settings.
• Make sure traffic between WiFi and the LAN is not blocked by the firewall on the NBG7815.
• Make sure you allow the NBG7815 to be remotely accessed through the WLAN interface. Check your
remote management settings.
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".
The WiFi connection is slow or intermittent.
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 WiFi devices.
To optimize the speed and quality of your WiFi connection, you can:
• Move your WiFi device closer to the NBG7815 if the signal strength is low.
• Reduce WiFi interference that may be caused by other WiFi networks or surrounding wireless
electronics such as cordless phones.
• Place the NBG7815 where there are minimum obstacles (such as walls and ceilings) between the
NBG7815 and the WiFi client. Avoid placing the NBG7815 inside any type of box that might block WiFi
signals.
• Reduce the number of WiFi clients connecting to the same NBG7815 simultaneously, or add
additional NBG7815s if necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the WiFi 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 NBG7815 is placed on a table or floor, point the
antennas upwards. If the NBG7815 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 WiFi
clients.
