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
240.) 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mode that is superseded by WPA-PSK and WPA2-PSK.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.
•
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 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 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 5
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 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.

IMPORTANT:
The WiFi mode of the guest WiFi network depends on the WiFi
mode of the main WiFi network. For you to be able to configure
WEP in the guest WiFi network, first configure the mode for the
main WiFi network as Up to 54 Mbps. For information about
configuring the WiFi mode, see
Manage the Basic WiFi Settings and
WiFi Security of the Main Network
on page
91.
To configure WEP security for the guest WiFi network:

From the
Encryption Strength
menu in the Security Encryption (WEP) section, select the
encryption key size:
•
64-bit
. Standard WEP encryption, using 40/64-bit encryption.
•
128-bit
. Standard WEP encryption, using 104/128-bit encryption. This selection
provides stronger encryption security.
9.
In the Security Encryption (WEP) Key section, generate the key automatically:
a.
In the
Passphrase
field, enter a passphrase.
b.
Click the
Generate
button.
For 64-bit WEP, four different WEP keys are generated and the four key fields are
populated with different WEP keys. For 128-bit WEP, only one WEP key is generated
and the four key fields are populated with the same WEP key.
c.
Specify the active key by selecting the
Key 1
,
Key 2
,
Key 3
, or
Key 4
radio button.
Only one key can be the active key.
To join the guest WiFi network, a user must enter the key value for the key that you
specified as the active key.

Control the WiFi Radios
The modem router provides internal WiFi radios that broadcast signals in the 2.4 GHz and
5
GHz ranges. By default, they are on so that you can connect over WiFi to the modem
router. When the WiFi radios are off, you can still use an Ethernet cable for a LAN connection
to the modem router.
You can turn the WiFi radios on and off with the
WiFi On/Off
button on the modem router, or
you can log in to the modem router and enable or disable the WiFi radios through the web
management interface. If you are close to the modem router, it might be easier to press the
WiFi On/Off
button. If you are away from the modem router or already logged in, it might be
easier to enable or disable the radios through the web management interface. You can also
turn the WiFi radios off and on based on a schedule. (See
Set Up a WiFi Schedule
on
page
110.)
Tip:
If you want to disable the WiFi radios of the modem router, use a wired
connection to avoid being disconnected when the WiFi radios turn off.
Use the WiFi On/Off Button
To turn the WiFi radios off and on with the WiFi On/Off button:
Press the
WiFi On/Off
button on the right side panel of the modem router for three
seconds.
If you turned off the WiFi radios, the WiFi LED turns off. If you turned on the WiFi radios,
the WiFi LED lights solid blue after about half a minute.
