Cannot Log in to the Wireless-N Modem Router
If you are unable to log in to the wireless-N modem 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
192.168.0.2 to 192.168.0.254. Follow the instructions in the online document that you can
access from “Preparing Your Network” in Appendix B for information about how to configure
your computer.
• If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and
MacOS will generate and assign an IP address if the computer cannot reach a DHCP server.
These auto-generated 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 192.168.0.1. This
procedure is explained in “Using the Restore Factory Settings Button to Reset the Router” on
page 7-10.
• 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.
The Ethernet port LEDs are off. If the Ethernet port LEDs do not light when the Ethernet connection is
made, check the following:
• Make sure that the Ethernet cable connections are secure at the
wireless-N modem router and computer.
• Make sure that power is turned on to the connected modem or
computer.
Wireless LEDs are off. If the Wireless LEDs do not come on, verify that the Enable Wireless
Router Radio check box is selected on the Wireless Settings screen.
See “Manually Configuring Your Wireless Network” on page 2-4.
