NETGEAR MR314 Reference Manual page 65

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, NETGEAR strongly
recommends that you make use of the security features of your wireless equipment. As a minimum
security precaution, you should change the ESSID setting of all devices on your network from the
factory setting to a unique password. Restricting access by MAC address filtering adds another
obstacle against unwanted hosts joining your network.
To hinder a determined eavesdropper, you should enable Wired Equivalent Privacy (WEP) data
encryption. However, there may be a significant degradation of the data throughput on the wireless
link when WEP is enabled.
For further information on wireless networking, refer to "Wireless Networking" in Appendix B,
"Network and Routing Basics."
