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

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 Router 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 Router (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 Router’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 Router 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 Router to change all settings back to their default. This means your current settings are 
lost. See 

 in the Troubleshooting for information on resetting your 

Router. 

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 

.

I cannot see or access the Login screen in the Web Configurator.

Make sure you are using the correct IP address.

• The default IP address is 

192.168.1.1

.

• If you changed the IP address (

), use the new IP address.

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