Each laptop and wireless device that you own must use the WEP password in order to connect to the wireless router. To find the security key, you will need to log into your router's administrator dashboard from a computer that is currently connected to the router.
1). Open your Internet browser on a computer that is connected to the wireless router.
2). Type the IP address for your router in the address bar of your browser. The IP address may vary depending on the brand and model of your router. You will find the default IP address listed in your router's instruction manual.
