Troubleshooting Internet Browsing

If your wireless router can obtain an IP address but your computer is unable to load any web pages

from the Internet, check the following:

•

Your computer might not recognize any DNS server addresses

. A DNS server is a host on

the Internet that translates Internet names (such as www addresses) to numeric IP addresses.

Typically, your ISP will provide the addresses of one or two DNS servers for your use. If you

entered a DNS address during the wireless router’s configuration, restart your computer.

Alternatively, you can configure your computer manually with a DNS address, as explained in

the documentation for your computer

.

•

Your computer might not have the wireless router configured as its default gateway

.

Reboot the computer and verify that the wireless router address (192.168.1.1) is listed by your

computer as the default gateway address.

Using the Ping Utility to Troubleshoot

Most computers and routers have a diagnostic utility called

ping

that sends a request to a target

device. The device then replies. The ping utility makes it easy to troubleshoot a network.

Testing the Path from Your Computer to Your Router

You can ping the wireless router to verify that the LAN path from your computer to your router is

set up correctly.

To ping the wireless router from a Windows PC:

1.

From the Windows task bar, click

Start

and select

Run

.

2.

In the field provided, type

ping

followed by the address of the router, as in this example:

ping www.routerlogin.net

3.

Click

OK

. You should see a message like this one:

Pinging www.routerlogin.net with 32 bytes of data

If the path is working, you see this message:

Reply from www.routerlogin.net: bytes=32 time=NN ms TTL=xxx

If the path is not working, you see this message:

Request timed out

If the path is not working correctly, you could have one of the following problems:

Troubleshooting

•

Wrong physical connections

–

Make sure the LAN port light is on. If the light is off, follow the instructions in

“Basic

Setup Checklist” on page 26

.

–

Check that the corresponding lights are on for your computer’s network interface card.

•

Wrong network configuration

–

Verify that the Ethernet card driver software and TCP/IP software are both installed and

configured on your computer.

–

Verify that the IP addresses for your router and your computer are correct and that both

addresses are on the same subnet (for example, 192.168.1.x/255.255.255.0).

Testing the Path from a Computer to the Internet

After verifying that the path between your computer and the wireless router works correctly, test

the path from your PC to the Internet.

To test the path using ping from a Windows PC:

1.

From the Windows task bar, click

Start

and select

Run

.

2.

In the field provided, type

cmd

.

A command screen will display.

3.

At the

>

prompt, type the following:

ping -n 10 <

IP address

>

where <

IP address

> is the IP address of a remote device such as your ISP’s DNS server.

4.

Press

Enter.

If the path is working correctly, replies as in the previous section will display. If you do not receive

replies:

•

Check that your PC has the IP address of your router listed as the default gateway. If the IP

configuration of your PC is assigned by DHCP, this information will not be visible in your

PC’s Network Control Panel. Verify that the IP address of the router is listed as the TCP/IP

default gateway.

•

Check to see that the network address of your PC (the portion of the IP address specified by

the netmask) is different from the network address of the remote device.

•

If your ISP assigned a host name to your PC, enter that host name as the Account Name in the

Basic Settings menu.

Restoring the Default Password and Configuration

Settings

You can restore the factory default configuration settings that reset the router’s user name to

admin,

the password to

password,

and the IP address to

192.168.1.1

.

To restore the factory default configuration settings:

1.

Use a sharp object such as a pen or a paper clip to press and hold the restore factory settings

button, located on the rear panel of the router, for about 5 seconds, until the Power light begins

to blink (see

“Back Panel” on page 5

).

2.

Release the restore factory settings button, and wait for the router to restart, and for the Power

light to stop blinking and become solid green.

The factory default settings will be restored so that you can access the router from your Web

browser using the factory defaults.

This procedure will erase all the current configuration settings and restore the factory

defaults.
