Chapter 4 Securing My Wireless The 5 GHz Wireless-N HD Access Point/Bridge WNHDE111 provides highly effective security features, which are covered in detail in this chapter. This chapter includes the following sections: • "Choosing Appropriate Wireless Security" on page 4-1 • "Changing Wireless Security Settings" on page 4-4 • "Viewing Advanced Wireless Settings" on page 4-6 • "Using Push 'N' Connect (Wi-Fi Protected Setup)" on page 4-7 • "Enabling Wireless Isolation" on page 4-10 • "Restricting Wireless Access by MAC Address" on page 4-11 • "Changing the Administrator Password" on page 4-12 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 802.11n/a wireless networks at ranges of up to 500 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. Stronger security methods can entail a cost in terms of throughput, latency, battery consumption, and equipment compatibility. In choosing an appropriate security level, you can also consider the effort compared to the reward for a hacker to break into your network. As a minimum, however, NETGEAR recommends using WEP with Shared Key authentication. Do not run an unsecured wireless network unless it is your intention to provide free Internet access for the public. 4-1 v1.1, May 2008
