N300 Wireless ADSL2+ Modem Router DGN2200v3
Preset Security
The modem router comes with preset security. This means that the Wi-Fi network name
(SSID), passphrase, and security option (encryption protocol) are preset in the factory. You
can find the preset SSID and passphrase on the bottom of the unit.
• W
i-Fi network name (SSID) identifies your network so devices can find it.
• Pass
phrase controls access to your network. Devices that know the SSID and the
passphrase can find your wireless network and connect.
Note: The preset SSID and passphrase are uniquely generated for every
device to protect and maximize your wireless security.
• Security option is the type of security protocol applied to your wireless network. The
security protocol in force encrypts data transmissions and ensures that only trusted
devices receive authorization to connect to your network. The preset security option is
WPA-PSK/WPA2-PSK mixed mode, described in Wireless Security Options on p
age 31.
The Wireless Settings screen lets you view an
d change the preset security settings.
However, NETGEAR recommends that you not change your preset security settings. If
you do decide to change your preset security settings, make a note of the new settings and
store it in a safe place where you can easily find it.
Security Basics
Unlike wired network data, wireless data transmissions extend beyond your walls and can be
received by any device with a compatible wireless adapter (radio). For this reason, it is very
important to maintain the preset security and understand the other security features available
to you. Besides the preset security settings described in the previous section, your modem
router has the security features described here and in Chapter 4, Security Settings.
