DescriptionField
From the Encryption Mode menu, select the enterprise mode:
• WPA [TKIP] +WPA2 [AES]. This type of security enables WiFi devices
that support either WPA or WPA2 to join the modem router’s WiFi
network. This is the default mode.
• WPA2 [AES]. 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 [TKIP] + WPA2 [AES] security.

7. Click the Apply button.
Your settings are saved.
8. Make sure that you can reconnect over WiFi to the network with its new security 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?
Configure WEP Legacy WiFi Security
Wired Equivalent Privacy (WEP) security is a legacy authentication and data encryption mode that is
superseded by WPA-PSK and WPA2-PSK.WEP limits the WiFi transmission speed to 54 Mbps (the modem
router is capable of speeds of up 300 Mbps in the 2.4 GHz band).
If you want to change the WiFi settings of the modem router’s main network, use a wired
connection to avoid being disconnected when the new WiFi settings take effect.
