Connect WiFi Devices to Your Router

To connect your computer or mobile device (such as a smartphone or gaming device) to your modem router’s WiFi network, you can use either the manual method or Wi-Fi Protected Setup (WPS) method.

Manual Method

  1. Open the software utility that manages your WiFi connections on the computer or mobile device that you want to connect to your modem router.
    This utility scans for all wireless networks in your area.
  2. Find and select your modem router’s WiFi network name (SSID).
    The SSID is on the product label.
  3. Enter the modem router’s password (or your custom password if you changed it) and click the Connect button.
    The password is on the product label.
  4. Repeat Steps 1–3 to add other devices.

WPS Method

If your computer or WiFi device supports WPS, you can use WPS to join the router’s WiFi network. NETGEAR calls WPS Push ‘N’ Connect.
Note: WPS does not support WEP security. If you are using WEP security, use the manual method.

  1. Press the WPS button on the router.
  2. Within two minutes, on your computer or mobile device, press its WPS button or click its onscreen WPS button.
    Note: For help with the WPS button on your computer or wireless device, check the instructions or online help that came with that computer or device. Some older equipment cannot use WPS.
    The WPS LED on the modem router lights solid green and the computer or mobile device is connected to your modem router.
  3. Repeat this process to add other WPS WiFi devices.
