Wireless Encryption on Your Home Network

Postby peter » Mon Dec 24, 2007 2:32 pm

It is often a good idea to have encryption on your home network. Without encryption, your neighbors can easily join your wireless network and share your DSL/Cable modem Internet connection without paying. In some extreme cases they may be able to take a look at files on your system.

Wireless encryption in homes is usually based on a password and you must use this password when you set it up your router. There is usually a security page in the router's Web interface that allows you to set it.

Things could go wrong. It's important to download and print the manual for your router model number. This will help to make the recovery process easier and will speed up the time it will take to get you back online.

Remember that the moment you activate encryption on your router you will get kicked out of your network as the router will use encryption and your PC will not.

If you decide to do this, take note of your new router selections:
  1. The authentication protocol you select (WPA / WEP)
  2. The encryption scheme (AES / TKIP)
  3. Your encryption password. Many routers don't ask you to confirm the password. I'd suggest cutting and pasting it from a document to make sure.
Once the router is completed you will have to add the password to your PC's NIC card immediately afterwards. I'd suggest you do a quick search beforehand to find out how to do that on your system.

Windows

In Windows XP you can find your wireless network configuration information using:
  1. "Control Panel > Network Settings".
  2. Double click on your wireless card
  3. Click on the "Properties" button
  4. Click on the "Wireless Networks" tab at the very top.
Follow the instructions on this link after step #2, modifying the steps to suit your network.

Other Precautions

If in the event that you find yourself locked out of your router due to adding security, most, if not all routers have a reset button located on the unit somewhere. It usually is a pinhole occasionally marked with the word "reset." To use it, the standard method is to activate the reset by sticking a slender object, like a pin into the hole until it "clicks." First try it with the power already on. If this fails to reset the router, try holding it in the "down" click position while powering the unit on. Resetting will make your router revert to its initial factory settings. You will now have to change these router settings back to what you had before you began this process. - Member contribution USNaviguide LLC
