Section 3 - Conguration
Wireless security helps to prevent unauthorized users from accessing your wireless network, or seeing data being passed
between the router and wireless clients. The DSL-2750B supports two popular wireless security protocols, you should select a
protocol based on the wireless clients which will be accessing your network.
Wired Equivalent Privacy (WEP) - This is an older form of wireless security and should only be used if your wireless clients do
not support the newer WPA or WPA2 protocols.
2.4G Wireless Security
Wi-Fi Protected Access (WPA/WPA2) - This is a newer and more secure protocol for wireless security. It uses a cipher combined
with a pre-shared key (password) to encrypt data being sent over the wireless network. It is recommended that you use this
security method if it is supported by your wireless clients.
