•

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

192.168.1.2 to 192.168.1.254. Refer to

“Preparing a Computer for Network Access” in

Appendix B

for instructions on how to verify TCP/IP properties and for instructions on how to

configure your computer.

•

If your router’s IP address has been 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

192.168.1.1. This procedure is explained in

“Restoring the Default Configuration and

Password” on page -7

.

•

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 factory default login name is

admin

and the password is

password

. Make sure that CAPS LOCK is off when entering this

information.

If the router does not save changes you have made in the Web Configuration Interface, check the

following:

•

When entering configuration settings, be sure to click Apply before moving to another menu

or tab, or your changes will be lost.

•

Click the Refresh or Reload button in the Web browser. The changes may have occurred, but

the Web browser may be caching the old configuration.

Troubleshooting the ISP Connection

If your router is unable to access the Internet, you should first determine whether the router is able

to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address, your

router must request an IP address from the ISP. You can determine whether the request was

successful using the Web Configuration Manager.

Note:

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.
