Is Your Wireless Router Secure?

2 Jan

If you have a wireless router in your home or office, be sure to set up the security features that are available. If you don’t, you may risk unauthorized access to your Internet connection or, even worse, unauthorized access to your computers.

Here are some simple steps you can take to secure your wireless router:

First, change the administration password. To access the configuration of your router, run a web browser such as Internet Explorer and enter the address of the router in the address bar at the top of the browser window. The address can usually be found on the bottom of the router and looks something like this: http://192.168.0.1/

You can also check the documentation for your router to find out more about how to configure it.

The first thing to do is to change the administration password. The default passwords for various routers are widely known and changing it will prevent someone else from getting in there and taking control.

Then, there are three easy things you can do to prevent unauthorized access to your router, computers and Internet connection:

Set up a pre-shared key
This is simply a password that you enter into the router configuration screen. Then, any device that is to access that router, and everything else connecting to it, must be configured with that password.

Enter the MAC addresses
Every wireless device has a unique Media Access Control (MAC) address. It looks something like this: 00:21:91:ff:33:c4. If you enter the MAC address of authorized devices into the router configuration, only those devices can access that router.

Turn off the broadcasting
Once you have your wireless devices set up, you can tell the router to stop broadcasting itself. This makes it invisible, but your authorized devices will still be able to access it.

One more thing to consider is turning on the router’s hardware firewall. Your Windows 7 computers have an effective software firewall to watch for suspicious network traffic, but you may have other devices such as a tablet or digital video recorder that connect wirelessly to the Internet and that do not have firewall protection. The router has a firewall that can be activated to protect those other devices.
