Wireless Security Options

Computers can connect over a 802.11g or 802.11n network at a range of up to 300 feet. Such

distances can allow for others outside your immediate area to access your network.

Unlike wired network data, your wireless data transmissions can extend beyond your walls and

can be received by anyone with a compatible adapter. For this reason, use the security features of

your wireless equipment. The WNR3500L router provides highly effective security features which

are covered in detail in this chapter. Deploy the security features appropriate to your needs.

There are several ways you can enhance the security of your wireless network:

•

WEP.

Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared

Key authentication and WEP data encryption block all but the most determined eavesdropper.

This data encryption mode has been superseded by WPA-PSK and WPA2-PSK.

•

WPA-PSK (TKIP), WPA2-PSK (AES)

. Wi-Fi Protected Access (WPA) using a pre-shared

key to perform authentication and generate the initial data encryption keys. The very strong

authentication along with dynamic per frame re-keying of WPA makes it virtually impossible

to compromise.

“Wireless

Networking Basics” in Appendix B
