DSL-2740B/DSL-2740R does not have any wireless security enabled whenit is shipped. This means that anyone within range of the wirelesssignal it transmits will be able to gain access to the computers onyour local network and use your Internet connection.

If you wish to secure your wireless network, we recommend usingWPA2-PSK or WPA-PSK. The WEP standard should not be used unless youneed to connect older devices that do not support WPA/WPA2.

Note: we recommend connecting to your router using a cableinstead of a wireless connection when making any changes to thewireless settings.
