Appendix A. Wireless security Overview
A1. WEP, WPA and WPA2 comparison
WEP, WPA-PSK and WPA2-PSK are standard wireless security options. When using any
one of them, each device in the
wireless network MUST use the SAME wireless security
option and network security key (also called password, passphrase or pre-shared key).
Otherwise, the wireless network will not function properly.

Note: WE
P is a deprecated wireless security algorithm. There are readily available
programs to crack the WEP encryption within minutes. Nonetheless, WEP is widely used
and is often the default wireless security option in older wireless devices.
