simultaneously supports the 2.4 GHz band for 802.11n, 802.11g, and 802.11b devices and the 5 GHz band for
802.11ac, 802.11n, and 802.11a devices.
The WiFi mode of the guest WiFi network depends on the WiFi mode of the main WiFi network. For example, if you
configure the WiFi mode for the main WiFi network as Up to 54 Mbps in the 2.4 GHz band, the guest WiFi network
also functions in the Up to 54 Mbps mode in the 2.4 GHz band. For information about configuring the WiFi mode,
see
View or Change the Basic WiFi Settings
on page 97.
The modem router provides two default guest networks with the following names (SSIDs):
•
2.4 GHz band
. NETGEAR-Guest
•
5 GHz band
. NETGEAR-5G-Guest
By default, these networks are configured as open networks without security but are disabled.You can enable one
or both networks.You can also change the SSIDs for these networks.
To set up a guest network:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
2.
Enter
.
A login window opens.
3.
Enter the modem router user name and password.
The user name is

Security Options
If you want to change the WiFi security, select one of the following WiFi security options for the 2.4 GHz band of the guest
WiFi network:
•
None
. An open WiFi network that does not provide any security. Any WiFi device can join the 2.4 GHz band of the
guest WiFi network. This is the default setting for the guest 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.Wired Equivalent Privacy (WEP) security is a legacy authentication and data encryption mode that is superseded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 configure the WiFi mode for the main WiFi network
as Up to 54 Mbps in the 2.4 GHz band (see
View or Change the Basic WiFi Settings
on page 97). For information
about configuring WEP, see
Configure WEP Legacy WiFi Security
on page 106.
•
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-PSK [AES] security to allow 802.11n devices to connect to the 2.4 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 2.4 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 2.4 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 2.4 GHz band
of the guest 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

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
234.) If it does, it is connected to the network.
•
Are you using the correct network name (SSID) and password?

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 modem router web pages. 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 modem router web pages.You can also turn
the WiFi radios off and on based on a schedule. (See
Set Up a WiFi Schedule
on page 247.)
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 top panel of the modem router for two seconds.
If you turned off the WiFi radios, the 2.4 GHz WiFi LED, 5 GHz WiFi LED, WiFi LED, and WPS LED turn off. If
you turned on the WiFi radios, these LEDs lights solid white.
If you want to disable the WiFi radio or radios of the modem router, use a wired connection
to avoid being disconnected when WiFi radio or radios turn off.
Tip
Enable or Disable the WiFi Radios
If you used the
WiFi On/Off
button to turn off the WiFi radios, you cannot log in to the modem router to turn them
back on.You must press the
WiFi On/Off
button again for two seconds to turn the WiFi radios back on.
To enable or disable the WiFi radios:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
2.
Enter
.
A login window opens.
3.
Enter the modem router user name and password.
The user name is
