Cannot Access the Router Menu

If you are unable to access the router’s menu 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 modem router.

• Make sure 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. Refer to “Preparing Your Network” in AppendixB to find your

computer’s IP address.

• If your computer’s IP address is shown as 169.254.x.x:, it might because recent versions of

Windows and MacOS 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 will set the router’s IP address to 192.168.0.1.

This procedure is explained in “Restoring the Factory Configuration Settings” in AppendixA.

• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet

Explorer, click Refresh to be sure the Java applet is loaded.

• Try quitting the browser and launching it again.

• Make sure you are using the correct login information. The login name is admin and the

default password is password. Make sure that Caps Lock is off when entering this

information.

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

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 in the Advanced Wireless Settings

screen. See “Advanced Wireless Settings” on page 2-15.
