Protect Your Network during Mobile Access Understand How a Wireless Network Works Going wireless generally requires connecting an internet "access point" — like a cable or DSL modem — to a wireless router, which sends a signal through the air, sometimes as far as several hundred feet.

Any device within range can pull the signal from the air and access the internet. Unless you take certain precautions, anyone nearby can use your network. That means your neighbors — or any hacker nearby — could "piggyback" on your network or access information on your device.

If an unauthorized person uses your network to commit crime or send spam, the activity could be traced back to your account. Using encryption is the most effective way to secure your network from intruders.

Two main types of encryption are available for this purpose: Your computer, router, and other equipment must use the same encryption.

WPA2 is strongest; use it if you have a choice. It should protect you against most hackers.

Consider buying a new router with WPA2 capability. Wireless routers often come with the encryption feature turned off. You must turn it on.

Introduction to Mobile Computing and Communications

The directions that come with your router should explain how. Limit Access to Your Network Allow only specific devices to access your wireless network.

Wireless routers usually have a mechanism to allow only devices with particular MAC addresses to access to the network. Your router directs traffic between your local network and the internet.

Strangers also could seize control of your router, to direct you to fraudulent websites. Change the name of your router from the default. The name of your router often called the service set identifier or SSID is likely to be a standard, default ID assigned by the manufacturer.

Change the name to something unique that only you know. Use long and complex passwords — think at least 12 characters, with a mix of numbers, symbols, and upper and lower case letters.

Never leave this feature enabled. Hackers can use them to get into your home network.
