Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the router. Read the following descriptions if
you are having problems. The examples below are illustrated in Windows
®
XP. If you have a dierent operating system, the screen captures on your
computer will look similar to the following examples.
Why can’t I access the web-based conguration utility?
When entering the IP address of the router (192.168.0.1 for example), you are not connecting to a website nor do you have to be connected to
the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must be on the same IP subnet to connect to the
web-based utility.
Make sure you have an updated Java-enabled web browser. We recommend the following:
• Microsoft Internet Explorer
®
6.0 and higher
• Mozilla Firefox 3.0 and higher
• Google™ Chrome 2.0 and higher
• Apple Safari 3.0 and higher
Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a dierent cable or connect
to a dierent port on the device if possible. If the computer is turned o, the link light may not be on.
Disable any Internet security software running on the computer. Software rewalls such as Zone Alarm, Black Ice, Sygate, Norton Personal Firewall,
and Windows® XP rewall may block access to the conguration pages. Check the help les included with your rewall software for more information
on disabling or conguring it.
Congure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click the button to restore the settings to
their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Make sure nothing is checked.
Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK three times.
• Close your web browser (if open) and open it.
Access the web management. Open your web browser and enter the IP address of your router in the address bar. This should open the login page
for your web management.
If you still cannot access the conguration, unplug the power to the router for 10 seconds and plug back in. Wait about 30 seconds and try
accessing the conguration. If you have multiple computers, try connecting using a dierent computer.
