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 on the option called WEP.
Select 128Bit from the WEP Encryption drop down box.
Put a dot into the WEP Key 1 radio button.
Now put the key you made up in the box called WEP Key 1.
