NWA-3160 Series User’s Guide

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

cables.

• Disconnect and re-connect the power adaptor to the NWA. 
• If the problem continues, contact the vendor.

I forgot the IP address for the NWA.

• The default IP address is 192.168.1.2.
• If you changed the IP address and have forgotten it, you might get the IP 

address of the NWA 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 NWA (it depends on the network), so enter this 

IP address in your Internet browser.You can also use the following methods to 

access the web configurator:

• If you know your NWA’s System Name, enter it in your browser’s URL bar. 

The default System Name is NWA-Series. See 

information on locating and changing the NWA’s System Name.

Note: If you changed the System Name, and want to log into the NWA using the 

System Name, you should enter a name not longer than 15 alphanumeric 
characters.

• If you know your NWA’s MAC (Media Access Control) address, enter its last six 

characters in your browser’s URL bar, in the format zyxelXX:XX:XX, where 

XX:XX:XX represents the MAC address characters. The MAC address is 

usually printed on a label on the NWA.

Note: The NWA has two MAC addresses; one for the wired interface (LAN, or Local 

Area Network) and one for the wireless interface (WLAN, or Wireless Local 
Area Network). Use the LAN MAC address when accessing the NWA over the 
wired network, and use the WLAN MAC address when accessing the NWA 
over the wireless interface.

• If this does not work, you have to reset the device to its factory defaults. See 

I forgot the password.
