Secure Your Wireless Network

1. Login to your wireless router
a) If you've never logged into your wireless router, look up the make and model of the router, and find
the default IP Address, username, and password, then login.
b) For example, if your wireless router has a default IP Address of 192.168.1.1, default username of
admin, and default password of blank. Login by doing the following:
1. Open Internet Explorer and type in the address http://192.168.1.1
2. When prompted, the username would be admin, and the password would be blank.
c) If the router's password is still set to the default password, it is important to change this password to
something else to keep an intruder from effectively kicking you off of your own network.
2. Enable MAC Filtering
This is probably the easiest way to keep intruders off of your wireless network although the least secure.
You can enable a White-list of MAC Addresses and then only the MAC Addresses that you specifically
put into this list will be able to use your Wireless. You'll have to remember this if a friend comes over
and tries to use your wireless network.
3. Enable Encryption
It's important to use encryption on your wireless network. Not only does it keep intruders off of the
network, it also keeps eavesdroppers from listening in on your network traffic. The two major types of
wireless encryption are listed below. Please also note that any encryption enabled on the wireless
router must also be enabled on each Wireless Device that needs to connect to the internet.
a) WEP – This is still the most common type of encryption enabled on most wireless routers. Please
note that this can be broken by serious hackers in about 2 minutes, but will keep out most neighbors
and passerby's.
b) WPA2 – This is becoming the most common type of encryption and is enabled on most new wireless
routers. WPA2 is much more secure than
WEP and has not been compromised yet, but is not
available on some older types of Wireless Devices.
Deciding between WPA2, WEP, or MAC Filtering
WPA2 Encryption is the most secure method for keeping intruders off your network.
If you have older devices that will not support WPA2, WEP is encouraged.
If you are unsure how to setup encryption, MAC filtering is least secure, but easiest to setup.

4. Disable SSID Broadcasting
This option decides whether people can or can not see your wireless signal. This is not necessarily
recommended because although this will keep your network invisible to the common nosy neighbor, it
will not protect your network from any serious hackers. It can also make setting up your own devices on
your wireless network more difficult. So, it's good to know how this works, but always use encryption
and don't rely on just disabling SSID broadcasts to keep your network secure.
5. Install Who's On My WiFi
Download and Install Who Is On My WiFi Software onto a desktop computer that is always on at your
home or office. Who's On My WiFi acts as a detection engine by scanning your network every few
minutes to see if anyone has gotten onto your network. People could get in by breaking WEP
encryption, faking through a MAC Filter, somehow breaking WPA2, or by good old fashioned hard line
plugging into your router directly instead of connecting through the wireless. Monitoring for intruders is
the final step in securing a Wireless Network.
