Make sure that the NB16DG power adaptor is connected to the device and plugged in to an appropriate
power source. Use only the supplied power adaptor.

Web Configuration
I cannot access the web configuration pages.
CORRECTIVE ACTION
STEP
CORRECTIVE ACTION
1
Make sure you are using the correct IP address of the NB16DG. You can check the IP address of the device
from the Network Setup configuration page.
2
Check that you have enabled remote administration access. If you have configured an inbound packet filter,
ensure your computer’s IP address matches it.
3
Your computer’s and the NB16DG’s IP addresses must be on the same subnet for LAN access. You can
check the subnet in use by the router on the Network Setup page.
4
If you have changed the devices IP address, then enter the new one as the URL you enter into the address
bar of your web browser.
5
If you are still not able to access the web configuration pages, reset the router to the factory default settings
by pressing the reset button for ten seconds and then releasing it. When the Power LED begins to blink, the
defaults have been restored and the NB16DG restarts. Navigate to 192.168.20.1 in your web browser and
enter “admin” (without the quotes) as the username and password.
The web configuration does not display properly.
STEP
CORRECTIVE ACTION
1
Delete the temporary web files and log in again. In Internet Explorer, click Tools, Internet Options and
then click the Delete Files ... button. When a Delete Files window displays, select Delete all offline
content and click OK. (Steps may vary depending on the version of your Internet browser.)
CORRECTIVE ACTION
Login Username and Password
I forgot my login username and/or password.
STEP
CORRECTIVE ACTION
1
Press the Reset button for ten seconds, and then release it. When the Power LED begins to blink, the defaults
have been restored and the NB16DG restarts.
You can now login with the factory default username and password “admin” (without the quotes)

It is highly recommended to change the default username and password. Make sure you store the username
and password in a safe place.

WLAN Interface
I cannot access the NB16DG from the WLAN or ping any computer on the WLAN.
STEP
CORRECTIVE ACTION
1
Check the Wi-Fi LED on the front of the unit and verify the WLAN is enabled as per the LED Indicator section.

If you are using a static IP address for the WLAN connection, make sure that the IP address and the subnet
mask of the NB16DG and your computer(s) are on the same subnet. You can check the routers configuration
from the Network Setup page.
