How To Ensure Wireless Network Security

Some hotspots are open, meaning that anyone can access them. For instance, if an airport or a restaurant provides open wireless network access, anyone within the range of the network can access the hotspot. Ranges indoors are usually 150 to 300 feet, but can be shorter if the building interferes with the radio signals. Outdoor ranges can be as high as 1,000 feet, but can also vary.

If you set up a wireless network in your home or office, you should secure the hotspot so that others cannot access the connection (and any hardware or files on the network). To do so, you need to add a WEP (Wired Equivalent Privacy) key. This encryption system requires that you enter this key to access the network.
