8. Set up and test your WiFi devices and computers to make sure that they can connect over 
WiFi.
If they do not, check the following:
•Is your WiFi device connected to your network or another WiFi network in your area? 
Some WiFi devices automatically connect to the first open network (without WiFi 
security) that they discover.
•Does your WiFi device display as a connected device in the web management 
interface? (See 
View Devices Currently on the Network on page 104.) If it does, it is 
connected to the network.
•Do you use the correct network name (SSID) and password? The default SSID and 
default password are on the product label.
Configure WPA/WPA2 Enterprise WiFi Security
Remote Authentication Dial In User Service (RADIUS) is an enterprise-level method for 
centralized Authentication, Authorization, and Accounting (AAA) management. To provide 
WPA/WPA2 enterprise WiFi security, the WiFi network that the modem router provides must 
be able to access a RADIUS server.
Note:WPS and WPA/WPA2 enterprise security cannot function together. 
When you enable WPA/WPA2 enterprise security, WPS is disabled.
Tip: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.

Use the WPS Wizard to Add a Device to the WiFi Network
WPS (Wi-Fi Protected Setup) lets you connect a computer or WiFi device to the modem 
router’s network without entering the WiFi network passphrase or key. Instead, you use a 
WPS button or enter a PIN to connect.
If you use the push button method, the WiFi device that you are trying to connect must 
provide either a physical button or a software button. If you use the PIN method, you must 
know the PIN of the WiFi device that you are trying to connect.
WPS supports WPA and WPA2 WiFi security. If your modem router network is open (no WiFi 
security is set, which is not the default setting for the modem router), connecting with WPS 
automatically sets WPA + WPA2 WiFi security on the modem router network and generates a 
random passphrase. You can view this passphrase (see 
Manage the Basic WiFi Settings and 
WiFi Security of the Main Network on page 36).
Use WPS with the Push Button Method
For you to use the push button method to connect a WiFi device to the modem router’s WiFi 
network, the WiFi device that you are trying to connect must provide either a physical button 
or a software button. You can use the physical button and software button to let a WiFi device 
join only the main WiFi network, not the guest WiFi network.
To let a WiFi device join the modem router’s main WiFi network using WPS with the 
push button method:
1. Launch an Internet browser from a computer or WiFi device that is connected to the 
network. 
2. Type http://www.routerlogin.net.

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 n\
etwork as Up to 
54
  Mbps in the 2.4 GHz band, the guest WiFi network also functions in the U\
p to 54 Mbps 
mode in the 2.4 GHz band. For information about configuring the WiFi mod\
e, see  Manage the

network cannot access WiFi devices or Ethernet devices that are connected to the 
main WiFi network. To allow access to the main WiFi network, select the Allow guests 
to see each other and access my local network check box.
Guest Wireless 
Network Name 
(SSID) The SSID is the 2.4 GHz WiFi band name. If you did not change the SSID, the default 
SSID displays, which is NETGEAR-Guest.
If you want to change the SSID in the 2.4 GHz WiFi band for the guest WiFi network, 
enter a 32-character (maximum), case-sensitive name in this field.
Security Options - Profile
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 
Manage the Basic 
WiFi Settings and WiFi Security of the Main Network on page 36). For information about configuring 
WEP, see Configure WEP Legacy WiFi Security for the Guest WiFi Network on page 52.
• WPA-PSK [TKIP]. WPA provides a secure connection but is superseded by WPA2. The WPA-PSK 
[TKIP] 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 
Manage the Basic WiFi Settings and WiFi Security of the Main 
Network on page 36).
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.
• 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 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.
