Wireless networks can be even less secure than wired networks, because anyone who has the most basic kinds of wireless network equipment at his disposal can tap into virtually any wireless network within range.

Even if you have little or no technical knowledge, you can secure your wireless network in little time with these 5 simple tips:

Secure your access point admin interface: The default passwords of most standard devices are already known to most hackers. So, when you set up your router through the web interface, change the default password and write it down somewhere safe.


Stop broadcasting your SSID: Your wireless router continuously transmits your SSID (Service Set Identifier). While this is useful in an office where many people is going to connect to your network, at home this is certainly not needed. Turn SSID transmission off as soon as you can. Wireless LAN "sniffers" will still be able to detect your network, but other than that, your network will mostly be shrouded from outsiders.

Use MAC address filtering: Turn on MAC address filtering on your wireless router configuration utility. By doing so, you can add the MAC addresses of all of your networking devices to the address pool of the router. This way, no one outside your home network will be able to access your network.

Reduce the power of transmission: Reduce the power of your wireless transmitter to such a degree that the signal does not reach outside your home. This will keep most outsiders at bay.

Disable remote administration tool: Your remote administration utility is seldom used. So, keeping it on exposes your network to outsiders. Turn it off for enhance your network security.
