Troubleshooting

To help diagnose a problem, first use the following troubleshooting checklist.

1. Confirm that you are using the AC power adapter that came with your router and that it is connected to the router and to an active wall outlet. Make sure the Power switch is switched to the on position. The LED should be lit.
2. Confirm that you have securely connected the telephone cable to the telephone wall jack and to the router. The LED should be lit if you have correctly configured DSL.
3. Confirm that you have secured the Ethernet cable(s) to the computer’s network interface card and to the Ethernet port(s) on the router (labeled 1, 2, 3, or 4). The corresponding LED should be lit on the front of the router.

For more information on the LEDs, see the Status LEDs section earler in this document.

Opening the Web User Interface

The Web User Interface will be your main tool for configuring, troubleshooting and monitoring the router. Follow this procedure to access it.

1. Start a Web browser.
2. Open the page http://192.168.1.1 (If you’ve modified the router’s LAN IP address, you must use the new one.)
3. A login window will appear:

   

   Enter a user name and password, then click OK. The default user name and password are both admin.

4. The Web User Interface opens with a status page.

   

If you cannot access the Internet...

A number of devices have to work together for your computer to access the Internet.

A. Your computer connects to your ADSL 4-Port Router via a wired connection.

B. The router connects to your Internet Service Provider (ISP) via ADSL over the phone network.

The first step in solving the problem is to diagnose the cause. There are a number of places where the connection from your computer to the Internet might fail.

Step 1: Can your computer connect to your ADSL 4-Port Router?

Open a Web browser to the router’s address: http://192.168.1.1 (Please note that if you’ve modified the router’s LAN IP address, you must use the new one.)

If the router’s Web User Interface appears, go to Step 3. Otherwise, the router may need to be restarted:

1. Turn the router’s power off with the switch on the back. Wait a few seconds and turn it back on again.
2. Wait one or two minutes as the router restarts.

Ensure that one end of the Ethernet cable is connected to your computer’s LAN port and the other end is connected to one of the Ethernet ports on the router. Also check that the corresponding LED is lit.

In the unlikely event that your computer is using a static IP address, either re-configure your computer to use a dynamic IP address or ensure that its static IP address is in the same network as the ADSL router. (That means that the IP address has the format 192.168.1.x where x can be any number between 2 and 254, inclusive.)

Now, please restart your computer. It will attempt to connect to the router. Continue on to step 2.

Step 2: Is your ADSL 4-Port Router responding?

Open your Web browser to the router’s address: http://192.168.1.1. If the router’s Web User Interface appears, please go to Step 3.

If the router’s Web User Interface doesn’t appear, the router may need to be restored to the default factory settings. (Please note that you will lose all of your router’s custom settings and will need to set it up again as if you were installing it for the first time. If you’ve made a backup of the settings, you will be able to restore them. Please click here for more information.)

1. With a thin tool such as a paper clip, press the Reset button on the back of the router for at least five seconds.
2. Wait about one or two minutes as the router restarts.
3. Please restart your computer so that it will connect to the router.
4. Try to access the router’s Web address at http://192.168.1.1

If the router's Web User Interface still does not appear, the firmware and/or default factory settings may have been corrupted. To find out, follow these steps:

1. Press and hold down the Reset button on the back of the router for more than 30 seconds.
2. Assign a static IP address to your computer, in the same subnet as your router's management IP address. (For example, the default management IP address for your router is 192.168.1.1. The computer IP address can be 192.168.1.5, subnet mask 255.255.255.0, and gateway IP address 192.168.1.1.)
3. Open a browser and try to open the http://192.168.1.1 address again. If anything opens, follow the on-screen instructions to re-load the firmware. You will need to get a new firmware file from your Internet Service Provider or from the www.usr.com Web site.
4. Close the Web browser and reinstate the dynamic IP address.

If the router’s Web User Interface still does not appear, the router may have failed. Please contact U.S. Robotics Customer Support. See the contact information for instructions.

If the router’s Web User Interface appears, please continue on to step 3.

Step 3: Can your ADSL 4-Port Router connect to the Internet?

If you have a connection between your computer and your router, it’s likely that the router is not connected to the Internet.

1. Close your Web browser and run EasyConfigurator.
   
   Windows Vista users: Click Windows Start > All Programs > U.S. Robotics EasyConfigurator.
Windows users: Press Start, then select Programs and U.S. Robotics EasyConfigurator.

Macintosh and Linux users: Double-click the EasyConfigurator icon on the desktop.

2. Click Status at the top of the page, and check the value of the Status field.

Sample status for a router connected to the Internet:



Sample status for a router not connected to the Internet:



If the status is CONNECTED or CONNECTED TO THE INTERNET but you still cannot access the Internet, please contact your ISP for assistance.

Otherwise, you need to configure your ADSL connection. Please click Configuration at the top of the EasyConfigurator window and go here for information on how to configure your ADSL connection.
