User’s Guide

Check the hardware connections. See the Quick Start Guide. 

Inspect your cables for damage. Contact the vendor to replace any damaged 
cables.

Disconnect and re-connect the power adaptor to the NBG4115. 

If the problem continues, contact the vendor.

I don’t know the IP address of my NBG4115.

The default IP address is 192.168.1.1.

If you changed the IP address and have forgotten it, you might get the IP address 
of the NBG4115 by looking up the IP address of the default gateway for your 
computer. To do this in most Windows computers, click Start > Run, enter cmd, 
and then enter ipconfig. The IP address of the Default Gateway might be the IP 
address of the NBG4115 (it depends on the network), so enter this IP address in 
your Internet browser.Set your device to Router Mode, login (see the Quick Start 
Guide for instructions) and go to the Device Information table in the Status 
screen. Your NBG4115’s IP address is available in the Device Information table. 

• If  the  DHCP setting under LAN information is None, your device has a fixed 

IP address. 

• If  the  DHCP setting under LAN information is Client, then your device 

receives an IP address from a DHCP server on the network. 

If your NBG4115 is a DHCP client, you can find your IP address from the DHCP 
server. This information is only available from the DHCP server which allocates IP 
addresses on your network. Find this information directly from the DHCP server or 
contact your system administrator for more information.

Reset your NBG4115 to change all settings back to their default. This means your 
current settings are lost. See 

 in the Troubleshooting 

for information on resetting your NBG4115.
