Description
Field
WPA [TKIP] +WPA2 [AES]
. This type of security enables WiFi devices
that support either WPA or WPA2 to join the
modem router
’s WiFi
network.
WPA2 [AES]
. 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 [TKIP] + WPA2 [AES] security.
If your network includes older devices only, select WPA [TKIP] security.
WPA [TKIP]
. WPA provides a secure connection. If your network
includes older devices only, select this type of security.

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 251.) If it does, it is connected to the network.

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superseded by WPA-PSK and WPA2-PSK.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).
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.
Tip
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 window opens.
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.

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.
In the
Passphrase
field, enter a phrase.
The phrase must consist of alphanumeric characters.
11.
Click the

button.
For each of the key fields, a value is generated and entered automatically.
12.
Specify the active key by selecting the

Key 3
, or
Key 4
radio button.
Only one key can be the active key. 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.
13.
To manually change the generated value for the key, do the following:
For 64-bit WEP, enter 10 hexadecimal digits (any combination of 0–9, A–F). The key values are
not case-sensitive.

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
View or Change the Basic WiFi Settings
on page 102).
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.

router
.
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 WiFi LED on the top panel of the
modem router
blinks white.
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.
