Security Options
If you want to change the WiFi security, select one of the following WiFi security options for the 2.4 GHz band of the guest
WiFi network:
• None. An open WiFi network that does not provide any security. Any WiFi device can join the 2.4 GHz band of the
guest WiFi network. This is the default setting for the guest WiFi network.
• WEP.Wired Equivalent Privacy (WEP) security is a legacy authentication and data encryption mode that is superseded
by WPA-PSK and WPA2-PSK.The WEP option displays only if you configure the WiFi mode for the main WiFi network
as Up to 54 Mbps in the 2.4 GHz band (see View or Change the Basic WiFi Settings on page 97). For information
about configuring WEP, see Configure WEP Legacy WiFi Security on page 106.
• WPA2-PSK [AES]. WPA2 provides a secure and fast connection but some older WiFi devices do not detect WPA2
and support only WPA. Select WPA2-PSK [AES] security to allow 802.11n devices to connect to the 2.4 GHz band of
the guest WiFi network at the fastest speed. If your network includes older devices that do not support WPA2, select
WPA-PSK [TKIP] + WPA2-PSK [AES] security.
To use WPA2 security, in the Passphrase field, enter a phrase of 8 to 63 characters.To join the 2.4 GHz band of the
guest WiFi network, a user must enter this passphrase.
• WPA-PSK [TKIP] + WPA2-PSK [AES].This type of security enables WiFi devices that support either WPA or WPA2
to join the 2.4 GHz band of the guest WiFi network. However, WPA-PSK [TKIP] is less secure than WPA2-PSK [AES]
and limits the speed of WiFi devices to 54 Mbps.
To use WPA + WPA2 security, in the Passphrase field, enter a phrase of 8 to 63 characters.To join the 2.4 GHz band
of the guest WiFi network, a user must enter this passphrase.
• WPA/WPA2 Enterprise.This type of security requires that your WiFi network can access a RADIUS server. For
information about configuring WPA/WPA2 Enterprise, see Configure WPA/WPA2 Enterprise WiFi Security on page
104.
The passphrase that provides users access to the guest WiFi network in the 2.4 GHZ band.The
passphrase is also referred to as the password or key.

By default, the guest WiFi network is disabled. To enable the guest WiFi network for the 5 GHz
WiFi band, select the Enable Guest Network check box.
Enable Guest Network
By default, the modem router broadcasts its SSID of the 5 GHz WiFi band so that WiFi stations
can detect the WiFi name (SSID) in their scanned network lists. To turn off the SSID broadcast
for the 5 GHz WiFi band for the guest WiFi network, clear the Enable SSID Broadcast check
box.
Enable SSID Broadcast
By default, WiFi clients that are connected to the 5 GHz WiFi band of the guest WiFi network
cannot access WiFi devices or Ethernet devices that are connected to the main WiFi network.
To allow access to the main WiFi network, select the Allow guests to see each other and
access my local network check box.
