N900 Wireless Dual Band Gigabit Router R4500 
Cannot Log In to the Router
If you are unable to log in to the router from a computer on your local network, check the 
following:
If you are using an Ethernet-connected computer, check the Ethernet connection 
between the computer and the router as described in the previous section.
Make sure that your computer’s IP address is on the same subnet as the router. If you are 
using the recommended addressing scheme, your computer’s address should be in the 
range of 192.168.1.2 to 192.168.1.254. 
If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and 
Mac OS generate and assign an IP address if the computer cannot reach a DHCP server. 
These autogenerated addresses are in the range of 169.254.x.x. If your IP address is in 
this range, check the connection from the computer to the router, and reboot your 
computer.
If your router’s IP address was changed and you do not know the current IP address, 
clear the router’s configuration to factory defaults. This sets the router’s IP address to 
192.168.1.1. For more information, see 
Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using 
Internet Explorer, click Refresh to be sure that the Java applet is loaded.
Try quitting the browser and launching it again.
Make sure that you are using the correct login information. The factory default login name 
is admin, and the password is password. Make sure that Caps Lock is off when you 
enter this information.
If you are attempting to set up your NETGEAR router as an additional router behind an 
existing router in your network, consider replacing the existing router instead. NETGEAR 
does not support such a configuration.
If you are trying to set up your NETGEAR router as a replacement for an ADSL gateway 
in your network, the router cannot perform some gateway services. For example, the 
router cannot convert ADSL or cable data into Ethernet networking information. 
NETGEAR does not support such a configuration.
Cannot Access the Internet
If you can access your router but you are unable to access the Internet, first determine 
whether the router can obtain an IP address from your Internet service provider (ISP). Unless 
your ISP provides a fixed IP address, your router requests an IP address from the ISP. You 
can determine whether the request was successful using the Router Status screen.
To check the WAN IP address: 
1.
Start your browser and navigate to an external site such as www.netgear.com.
2.
Access the router interface at www.routerlogin.net.
3.
Select Administration > Router Status.
