Most broadband routers and other wireless access points include an optional feature called MAC address filtering, or hardware address filtering.

It improves security by limiting the devices that can join a network.

However, since MAC addresses can be spoofed or faked, is filtering these hardware addresses actually useful, or is it a waste of time.

On a typical wireless network, any device that has the proper credentials (knows the SSID and password) can authenticate with the router and join the network, obtaining a local IP address and therefore access to the internet and any shared resources.

Before letting any device join the network, the router checks the devices MAC address against a list of approved addresses.

If the clients address matches one on the routers list, access is granted as usual; otherwise, its blocked from joining.

To set up MAC filtering on a router, the administrator must configure a list of devices that are allowed to join.

The physical address of each approved device must be found and then those addresses need to be entered into the router, and the MAC address filtering option turned on.

Most routers display the MAC address of connected devices from the admin console.

Once you have the list of MAC address, go into the router settings and put them in their proper places.

For example, to enable the MAC filter on a Linksys Wireless-N router, go to the Wireless Wireless MAC Filter page.

In theory, having a router perform this connection check before accepting devices increases the chance of preventing malicious network activity.

The MAC addresses of wireless clients cant truly be changed because theyre encoded in the hardware.

However, critics have pointed out that MAC addresses can be faked, and determined attackers know how to exploit this fact.

An attacker still needs to know one of the valid addresses for that network to break in, but this too is not difficult for anyone experienced in using network sniffer tools.
