DescriptionField
By default, the modem router broadcasts its SSID so that WiFi stations can detect the WiFi name
(SSID) in their scanned network lists.To turn off the SSID broadcast, clear the Enable SSID
Broadcast check box.Turning off the SSID broadcast provides additional WiFi security, but users
must know the SSID to be able to join the WiFi network of the modem router.
Enable SSID Broadcast
By default, 20/40 MHz coexistence is enabled to prevent interference between WiFi networks in
your environment at the expense of the WiFi speed. If no other WiFi networks are present in your
environment, you can clear the Enable 20/40 MHz Coexistence check box to increase the WiFi
speed to the maximum supported speed.

Security Options
This information applies to the 2.4 GHz WiFi network.
We recommend that you do not change your preset security settings (WPA2-PSK [AES]).Note
If you must change the WiFi security, select one of the following WiFi security options for the modem router’s WiFi network:
• None. An open WiFi network that does not provide any security. Any WiFi device can join the network.We recommend
that you do not use an open 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• WEP.Wired Equivalent Privacy (WEP) security is a legacy authentication and data encryption mode that is superseded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 select Up to 54 Mbps from the Mode menu. For
information about configuring WEP, see Configure WEP Legacy WiFi Security on page 103.
• WPA-PSK [TKIP]. WPA provides a secure connection but is superseded by WPA2. The WPA-PSK [TKIP] option
displays only if you select Up to 54 Mbps from the Mode menu.
To use WPA security, in the Passphrase field, enter a phrase of 8 to 63 characters.To join the modem router’s WiFi
network, a user must enter this passphrase.
• WPA2-PSK [AES]. This option is the default setting.This type of security enables WiFi devices that support WPA2 to
join the modem router’s 2.4 GHz WiFi network. If you did not change the passphrase, the default passphrase displays.
The default passphrase is printed on the product label (see Bottom Panel Product Label on page 17). WPA2 provides
a secure connection but some older WiFi devices do not detect WPA2 and support only WPA. If your network includes
such older devices, select WPA-PSK [TKIP] + WPA2-PSK [AES] security.
We recommend that you do not change the default passphrase. If you must change the passphrase, in the Passphrase
field, enter a phrase of 8 to 63 characters.To join the modem router’s 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 modem router’s 2.4 GHz 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 this type of security, in the Passphrase field, enter a phrase of 8 to 63 characters. To join the modem router’s
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
101.
