Choosing Appropriate Wireless Security
Unlike wired networks, wireless networks allow anyone with a compatible adapter to receive your
wireless data transmissions well beyond your walls. Operating an unsecured wireless network
creates an opportunity for outsiders to eavesdrop on your network traffic or to enter your network
to access your computers and files. Indoors, computers can connect over wireless networks at
ranges of up to 300 feet. Such distances can allow for others outside your immediate area to access
your network. Use the security features of your wireless equipment that are appropriate to your
needs.
The time it takes to establish a wireless connection can vary depending on both your security
settings and router placement.
