6. Click the Apply button.
Your settings are saved.
7. Make sure that you can reconnect over WiFi to the guest network.
If you cannot connect over WiFi, check the following:
• If your computer or WiFi 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.
• Does your WiFi device display as an attached device? (See
View Devices Currently
on the Network on page 237.) If it does, it is connected to the network.
• Are you using the correct network name (SSID) and password?
Configure WEP Legacy WiFi Security for the Guest WiFi
Network
Wired Equivalent Privacy (WEP) security is a legacy authentication and data encryption
mode that is superseded by WPA-PSK and WPA2-PSK. WEP supports speeds of up to
54 Mbps (the modem router is capable of speeds of up to 300 Mbps in the 2.4 GHz band).
Security Options - Profile
If you want to change the WiFi security, select one of the following WiFi security options for the 5 GHz band
of the guest WiFi network:
• None.
An open WiFi network that does not provide any security. Any WiFi device can join the 5 GHz
band of the guest WiFi network. This is the default setting for the guest WiFi network.
• WP
A2-PSK [AES]. WP
A2 provides a secure and fast connection but some older WiFi devices do not
detect WPA2 and support only WPA. Select WPA2 to allow 802.11n devices to connect to the 5 GHz
band of the guest WiFi network at the fastest speed. If your network includes older devices that do not
support WPA2, select WP
A-PSK [TKIP] + WPA2-PSK [AES] security.
To use WPA2 security, in the Passphrase field, enter a phrase of 8 to 63 characters.

band of the guest WiFi network, a user must enter this passphrase.
• WP
A-PSK [TKIP] + WPA2-PSK [AES]. This type of security enables WiFi devices that support either
WP
A or WPA2 to join the 5 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
5 GHz band of the guest WiFi network, a user must enter this passphrase.
