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 192.168.0.1.
You should see a box prompting you for your username and password. Enter your username and password now.
Click the Ok button to log in to your router.
Please visit our Default Router Passwords page if the username and password shown below did not work for you.
If you can't login to your router because you forgot your router username and password, use our How to Reset a Router Password guide to set your router back to its factory settings.
Click the Advanced link near the left side of the page.
You should now see a new menu. In this new menu, click Wireless.
In the box called ESSID 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.
Select 128-bit WEP from the WEP Encryption drop down box.
Put a dot into the Key 1 radio button.
Now put the key you made up in the box called Key 1.
When you're finished, click Apply near the bottom of the screen to save your changes.
And that's it! You're done!
