• 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
234.) If it does, it is connected to the network.
• Are you using the correct WiFi 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 97).
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 a web browser from a computer or WiFi device that is connected to the network.
2. Enter http://www.routerlogin.net.
A login window opens.
3. Enter the modem router user name and password.
The user name is admin.The default password is password. The user name and password are case-sensitive.
The BASIC Home page displays.
