2. Select a radio button.
• Push and Connect (recommended). Either click the button or press the WPS
button on the rear panel of the Internet adapter.
• PIN Number. Select the radio button and a PIN displays.
The Internet adapter tries to join the wireless network for 2 minutes if you are using Push
'N' Connect, or 4 minutes if you are using a PIN.
3. Go to the router.
• If you are using Push 'N' Connect, press the router's WPS button.
• If you are using a PIN, log in to the router and type the PIN from your Internet adapter
in its WPS screen.
4. Go back to the computer that is connected to the Internet adapter, and make sure that you
are connected to the wireless network.
• When WPS is running, the WLAN LED blinks, alternating between green and amber.
• If the computer does not to connect with WPS, the WLAN LED is solid red for 5
seconds.
• If the computer does connect using WPS, the WLAN LED is solid green for 5 seconds

If you got WPS capability on the device you are trying to connect you can push the WPS-button on the router, or you can login to the administration interface on the router (IP-address might be underneath unless you don't know it) and change the password to your liking. If you don't know the login and password for your interface then i guess the last resort is to find the reset button on the router and use the provided login that usually is found on a sticker underneath the device (your router), and simply set a new password for your WIFI.

CALL YOUR ISP FIRST.
wi-Fi Protected Setup (WPS) is a standard for easy and secure wireless network set up and connections. Some of NETGEAR's products use the name Push 'n' Connect for WPS. To use WPS, your product must support WPS and be compatible with WPA security. WPS can automatically set up a random network name (SSID) and strong WPA wireless security for wireless routers, access points, computers, adapters, Wi-Fi phones, and other electronic devices. WPS lets you use a push button or enter a personal identification number (PIN) instead of manually entering a network name (SSID) and password:

• Push button. The WPS button is either on the product or a clickable button on a wizard or utility screen.

The Linksys WRT160N has WPS (Wi-Fi Protected Setup). If you are using WPA-PSK encryption (recommended), then you can easily connect the C4780 to your wireless network using WPS:
