Wireless security settings

[Kenyth]

Most wireless routers offer MAC address filtering. This is the only security method I've used and it's near impossible to defeat.

Every network connection device, whether it's a USB Wireless connection, built-in wireless, or built-in hardwired LAN port, has a MAC Address. This is a unique code that identifies that specific piece of hardware. If you buy 2 of the same device, each will have a different MAC address.

Just log in to your wireless router (be sure to change the SSID name and most importantly - CHANGE THE PASSWORD), and enable MAC Address filtering. Enter the MAC Address of each device and assign each a name. (The name does not have to match the name you originally assigned the computer.) Be sure to apply or save changes and reboot your router.

To get the MAC address for your network device:

1. In Windows, click "Start", then "Run".
2. Type in cmd , and hit Enter
A black window (DOS box or command prompt) will appear.
3. Type in ipconfig /all (note: there is a space before the slash, but not after)
4. Scroll through the info that appears. You will have one or more entries titled "Ethernet adapter Local Area Connection". There might be a number at the end.
Three lines down will be the "Physical Address". That is the MAC Address. Typically, when you enter it in your router's filter tool, you won't type the dashes or colons.

I even have my router's SSID (name) set to broadcast for maximum compatibility. It's never been hacked, even though I suspect the kids in both houses next door have tried.

I hate to break it to you, but MAC address and IP cloning are not difficult. As a matter of fact, most home network equipment now has the capability built in. A linksys wireless router or access point can be set as a wireless bridge or client and it has an option for you to enter the MAC address you wish to use. This is primarily meant to be used in a constructive way.

Packet sniffing is the problem. A packet sniffer will capture every bit of information in a packet and show it to the user. Unencrypted radio transmissions broadcast all your information for anyone with a reciever to hear. Now mind you, it is another lock on the door that someone has to break through, but it's no effective secuirity system.
