I am no longer able to access the Internet.

1. If you can no longer access the Internet, first see the "Basic Troubleshooting Procedure" section on the main Troubleshooting page.
2. If you are on a computer running Windows, run the USRobotics Network Test from the Troubleshooting folder on the USRobotics Installation CD-ROM.

   If you run the USRobotics Network Test, follow the instructions in the utility, and still cannot connect to the Internet, manually step through the remaining procedures below.

3. When your computer connects to the Internet using the router, a number of devices have to work together. There are a number of places where the connection from your computer to the Internet might fail.

   • Your computer connects to your router via a wireless or wired adapter.

   • Your router connects to your Internet Service Provider (ISP).

The following procedure covers the areas where we're going to troubleshooting the connections in your network and the router to figure out where the network problems is:

1. Verify the wired or wireless adapter can connect to the router. If your wireless adapter cannot communicate with the router, your computer cannot access the Internet.
2. Verify the router's connection to the Internet. Your Internet connection must be up and functioning.

Verify the Wired or Wireless Adapter Can Connect to the Router

1. Start a Web browser. In the location or address line type 192.168.1.1 and press ENTER. If you can access the router's configuration pages, try again to access the Internet.

Note: If you have modified the router's IP address, enter the new IP address instead of 192.168.1.1.

Wired connections:

• If you can connect to the router's configuration pages but still cannot connect to the Internet: The problem is the router's connection to your ISP. Go to "Verify the Router's Connection to the Internet".
• If you cannot connect to the router's configuration pages: Go to Step B.

Wireless connections:

• If you can connect to the router's configuration pages: The problem is the router's connection to your ISP. Go to "Verify the Router's Connection to the Internet".
• If you cannot connect to the router's configuration pages: Continue with this procedure.
  1. Try a wired connection between the computer and your router.
     1. Connect an Ethernet cable between your computer's LAN port and a LAN port on the router. Ensure that the corresponding LAN LED on the router is lit.
     2. Start a Web browser. In the location or address line type 192.168.1.1 and press ENTER. Try again to access the Internet.

        Note: If you have modified the router's IP address, enter the new IP address instead of 192.168.1.1.

     • If you can connect to the router's configuration pages and the Internet: The problem is with your wireless adapter. See the documentation for your wireless adapter.
     • If you cannot connect to the router's configuration pages: Go to Step B.
     • If you can connect to the router's configuration pages: Continue with this procedure.
  2. Go to the Status page of the router and verify that the wireless utility for the adapter is using the correct Network Name (SSID) and that the wireless security settings match wireless security settings of the router. See the documentation of your wireless adapter for information on how to find and change your wireless security settings.
  3. On the Wireless> Setup page, verify that Allow wireless connections and Broadcast Network name are checked. Click Apply at the bottom of the page if you make any changes.
  4. Go to Security > MAC Filter page to determine if you have a MAC Filter enabled on your router. If the filter is set to Allow these devices you need to add the MAC address of the network adapter that cannot connect to the network to the filtering list.
  5. Disconnect the computer from the router and re-establish your wireless connection to the router.
  6. Try again to access the router's configuration pages at 192.168.1.1.
     • If you can connect to the router's configuration pages and still cannot access the Internet: Go to "Verify the Router's Connection to the Internet".
     • If you cannot connect to the router's configuration pages: Continue with this procedure.

2. Release and renew your adapter's network connection.

Verify the Router's Connection to the Internet

1. Check the LEDs on your router to determine that the router is connected to the Internet.
2. Verify that your router is connected to your wall jack.
3. If you still cannot access the Internet, click WAN Setup on the Internet menu and use the page to configure the gateway's Internet connection. (If you have a DSL modem, you may be required to enter the login information your ISP provided.)

   Note: If the WAN protocol is static, you will need to make sure the WAN IP address of the gateway is a valid static IP address. A valid static IP address is one that is provided by your ISP or is in the same subnet as the device that is connected to the WAN port of the gateway.

4. Restart your computer.
5. Try to access the Internet again.

If you still cannot access the Internet: The problem is with your ISP. Contact your ISP's Customer Support to determine if there is a problem with your modem or Internet connection.
