NWA Access and Login

I forgot the IP address for the NWA.

The default IP address is

192.168.1.2

If the NWA is working as a DHCP client and receives an IP address from a DHCP server, check the

DHCP server for the NWA’s IP address.

If you configured a static IP address and have forgotten it, you have to reset the device to its

factory defaults. See

Section 2.2 on page 20

I forgot the password.

The default password is

1234

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

Section 2.2 on page

I cannot see or access the

screen in the web configurator.

Make sure you are using the correct IP address.

•

The default IP address is 192.168.1.2.

•

If you changed the IP address (

Section 7.4 on page 93

), use the new IP address.

•

If you changed the IP address and have forgotten it, see the troubleshooting suggestions for

forgot the IP address for the NWA.

Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick

Start Guide and

Section 1.7 on page 18

Make sure your Internet browser does not block pop-up windows and has JavaScript and Java

enabled. See

Section 12.1 on page 123

Make sure your computer is in the same subnet as the NWA. (If you know that there are routers

between your computer and the NWA, skip this step.)

•

If there is no DHCP server on your network, make sure your computer’s IP address is in the

same subnet as the NWA.

Reset the device to its factory defaults, and try to access the NWA with the default IP address. See

Chapter 2 on page 20

If the problem continues, contact the network administrator or vendor, or try one of the advanced

suggestions.
