One problem with wireless networks is that people who have wireless devices that are within the range of your network can access them. Even if you have set up a password for your wireless network, that password can also be hacked and access to your network can be gained. One way to further tighten up your network security is through MAC filtering.
MAC filtering is a network security procedure that only allows access to registered MAC addresses. A MAC address is the unique ID of a network device; no two computers or network device has the same. What this means is that only registered and authorized machines can access your wireless network. So even if they somehow managed to break or hack your password, they won’t still have access if their address is not registered. This is a very effective way to ensure the network security of your wireless home network.
What you need to do is enable the MAC filtering function of your wireless router or access points. Most routers at present have this function. Next, you need to input the MAC address of the computers in your home network. Getting the MAC address is different from one operating system to another, but this should be found in the properties of the network device. Check your computer’s manual or technical support for the procedure on getting the MAC address.
So, if you’re very particular about the network security of your wireless network, then one thing you can do is to enable MAC filtering in your network.

Secure Your Home Wireless Network And Keep Hackers Out
October 7th, 2009
One of the most important, yet under-implemented features of any home wireless network is security. Many people worry only about file sharing and network printing. But many people underestimate the need for security or simply do not understand it. Security is important because unlike conventional wired networks, wireless signals are transmitted across a broader spectrum and thus can be easily picked up.
With the ever growing threat of identity theft you want to take the steps necessary to secure your home wireless network. There are some minor threats and major threats to your personal information. On the minor side an intruder may easily connect to your unsecured wireless network and use it for free internet access. This is called piggybacking. These are minor threats to your privacy.
A major threat is a hacker who is looking to attack your network and hack into it and access your files and personal data. Once they have this they can easily start stealing your identity or selling it to someone who will.
Wireless security can easily be implemented by following a few guidelines. One of the most important features is MAC address filtering. Each computer has a unique MAC address. In your network configuration you enter the MAC addresses of your PCs and laptops. Any other computer that is not specified in your network will be blocked from accessing it.
Another important network security feature is disabling the broadcast of the SSID, or name of your network. It is best to refer to the manufacturer’s documentation for specifics. Most of the required security features are built in the wireless router and this is the first point that needs to be secured. Many of the security settings are turned off by default. Make sure you turn them on for best security.
You can secure and manage your network yourself if you have the time or you can buy a home networking software package that does it for you automatically. There are some good programs out there for under $30 that will secure and repair your home network.
