Open a web browser like Internet Explorer or Firefox. Enter the internal IP address of your router in the address bar of your browser.
If you do not know your routers internal IP address please read our How To Find Your Routers IP Address guide.
In the picture above the address bar has http://www.google.com in it. Just replace all of that with the internal IP address of your router.
By default the IP address should be set to 192.168.123.254.

You should see a box prompting you for your password. Enter your password now. By default your password is admin. Click the Login button to log in to your router.
Please visit our Default Router Passwords page if the username and password shown above do not work for you.
Click the Basic Setting link near the top of the page.

Click the Wireless link near the left side of the page.

In the box called Network ID(SSID) put a name that you make up. You will need to remember this name because it will be used to connect to your wireless network. Do not make it obvious to guess, the network name should be difficult for your neighbors to guess. If you can not think of anything, simply use your first name.
In the box called Channel, pick a random channel number. Channels make it so that you and your neighbors can use your own wireless networks without interfering with each other. By picking a random channel you reduce the chance of your neighbor using the same channel as you.
Turn off the option called SSID Broadcast. This turns off the broadcast of your networks name making it more difficult for other people to find your network. You do not want to broadcast your networks name.
Put a dot into the Enable IEEE 128 bit Shared Key security radio button.
Put a dot into the WEP Key 1 radio button.
Now put the key you made up in the box called WEP Key 1.
When you're finished, click Save near the bottom of the screen to save your changes.
And that's it! You're done!
