In order to connect to your home wireless router, your computer must either have built-in wifi or you must use a wireless adapter. If your wireless router or the wireless adapter for your computer came with a setup CD, install the software onto your computer before you attempt to log into your home wireless router.
Open your web browser, such as Internet Explorer or Firefox and type in the IP address of your wireless router. This information should be included with your router. The default IP address for D-Link and Netgear home wireless routers is 192.168.0.1. The default IP address for Linksys home wireless routers is 192.168.1.1. If you are not sure what the correct IP address is for your home wireless router, use an Ethernet cable to connect your computer to your router. Open your web browser and go to the website of your home wireless router's manufacturer to find out the correct IP address. Write this IP address down, disconnect the Ethernet cord from between the router and the computer and proceed to log into your wireless router with the IP address.
Follow the log in instructions included with your wireless router. If you do not have any instructions, try leaving the user name file

password into the password field. If this does not work, try
admin for the user name and
password for the password, or
admin for both the user name and the password.
Once you have logged into your home wireless router, be sure to change the wireless network name, select an administrative password and use Wireless encryption (WEP) or Wi-Fi Protected Access (WPA) to protect your home wireless network. Then sit back and enjoy your wireless router from any computer in your home.
