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 802.11g/n 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.
