7.
Click the
Apply
button.
Your settings are saved.
If you connected over WiFi to the network and you changed the SSID, you are
disconnected from the network.
8.
Make sure that you can reconnect over WiFi to the network with its new settings.
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.
If your computer or WiFi device is trying to connect to your network with its old
settings (before you changed the settings), update the WiFi network selection in your
computer or WiFi 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
169.) If it does, it is connected to the network.
Are you using the correct network name (SSID) and password?
Security Options
This information applies to the 5 GHz WiFi network.
Note:
NETGEAR recommends that you do
not
change your preset security settings (WPA2-PSK [AES]).
If you must change the WiFi security, select one of the following WiFi security options for the modem
router’s WiFi network:
None
. An open WiFi network that does not provide any security. Any WiFi device can join the network.
NETGEAR recommends that you do
not
use an open WiFi network.
WPA2-PSK [AES]
. WPA2 security is the default setting and enables WiFi devices that support WPA2
to join the 5 GHz main WiFi network of the modem router. If you did not change the passphrase, the
default passphrase displays. The default passphrase is printed on the product label (see
Bottom Panel
Product Label
on page
13).
WPA2 allow 802.11ac and 802.11na devices to connect to the 5
GHz band of the main WiFi network at
the fastest speed. 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-PSK [TKIP] +
WPA2-PSK [AES] security.
NETGEAR recommends that you do not change the default passphrase. If you must change the
passphrase, in the
Passphrase
field, enter a phrase of 8 to 63 characters. To join the 5
GHz band of the
main 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 main WiFi network of the modem router. However, WPA-PSK [TKIP]
is less secure than WPA2-PSK [AES] and limits the speed of WiFi devices to 54 Mbps.
To use this type of security, in the
Passphrase
field, enter a phrase of 8 to 63 characters. To join the
5
GHz band of the main WiFi network, a user must enter this passphrase.
Passphrase
The passphrase that provides users access to the WiFi network in the 5 GHz band. The
passphrase is also referred to as the password or key.

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). WEP is available only for the 2.4 GHz band.
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.
To configure WEP security:
1.
Launch an Internet browser from a computer or WiFi device that is connected to the
network.
2.
Type
.
A login screen displays.
3.
Enter the user name and password for the modem router.
The user name is
admin
. The default password is
password
. The user name and
password are case-sensitive.
4.
Click the
OK
button.
The BASIC Home screen displays.
5.
Select
Wireless
.
The Wireless Settings screen displays.
6.
From the
Mode
menu, select
Up to 54 Mbps
.
The screen adjusts to display the
WEP
radio button.
7.
In the Security Options section, select the
WEP
radio button.

From the
Authentication Type
menu, select one of the following types:
Automatic
. Clients can use either Open System or Shared Key authentication.
Shared Key
. Clients can use only Shared Key authentication.
9.
From the
Encryption Strength
menu, 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 higher encryption security.
10.
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.
11.
Enter the value for the key:
For 64-bit WEP, enter 10 hexadecimal digits (any combination of 0–9, A–F). The key
values are not case-sensitive.
For 128-bit WEP, enter 26 hexadecimal digits (any combination of 0–9, A–F). The key
values are not case-sensitive.
To join the modem router’s WiFi network, a user must enter the key value for the key that
you specified as the active key.
12.
Click the
Apply
button.
Your settings are saved.
13.
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 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.
If your computer or WiFi device is trying to connect to your network with its old
settings (before you changed the settings), update the WiFi network selection in your
computer or WiFi 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
169.) If it does, it is connected to the network.
Are you using the correct network name (SSID) and password?
Use WPS 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
56).
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
.
A login screen displays.
3.
Enter the user name and password for the modem router.
The user name is
admin
. The default password is
password
. The user name and
password are case-sensitive.

4.
Click the
OK
button.
The BASIC Home screen displays.
5.
Select
ADVANCED > WPS Wizard
.
The screen displays a description of the WPS method.
6.
Click the
Next
button.
By default, the
Push Button (recommended)
radio button is selected.
7.
Either click the
button onscreen or press the
WPS
button on the back panel of the
modem router and release it quickly.
Note:
The button is labeled
Reset WPS
.
WARNING:
If you press the WPS button on the back panel but do not release it
quickly, the modem router resets to factory default settings.
For two minutes, the modem router attempts to find the WiFi device (that is, the client)
that you want to join the modem router’s main WiFi network.
During this time, the WPS LED
on the top panel of the modem router blinks green.
8.
Within two minutes, go to the WiFi device and press its
WPS
button to join the modem
router’s main WiFi network without entering a password.
After the modem router establishes a WPS connection, the WPS LED lights solid green
again and the Add WPS Client screen displays a confirmation message.
9.
To verify that the WiFi device is connected to the modem router’s main WiFi network, select
BASIC > Attached Device
.
The WiFi device displays onscreen.
