Security Options
This information applies to the 5 GHz WiFi network.
If you 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.
• 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 5 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 13). 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.
If you 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 5 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 91.
6. Click the Apply button.
Your settings are saved.
If you connected over WiFi to the network and you changed the SSID, you are disconnected from the
network.
7. Make sure that you can reconnect over WiFi to the network with its new settings.
If you cannot connect over WiFi, check the following:
• If your WiFi-enabled computer or mobile device is already connected to another WiFi network in your
area, disconnect it from that WiFi network and connect it to the WiFi network that the modem router
provides. Some WiFi devices automatically connect to the first open network without WiFi security
that they discover.
• If your WiFi-enabled computer or mobile device is trying to connect to your network with its old
settings (before you changed the settings), update the WiFi network selection in your WiFi-enabled
computer or mobile device to match the current settings for your network.
• Does your WiFi device display as an attached device? (See View Devices Currently on the Network
on page 210.) If it does, it is connected to the network.
• Are you using the correct network name (SSID) and password?
