How to Reset Wireless Settings
If you are experiencing a loss of Internet connection, your technical support department may require you to reset your wireless settings. Also, if you have misplaced or forgotten the user name and password for your router or modem, you can reset the wireless settings to the factory defaults. Each brand of modem offers a universal user name and password. Resetting the wireless settings of your router also refreshes the signal so you can receive a new, high-speed connection from your Internet service provider.
Restart your computer.
Press the reset button of your modem using a sharp object like a gem clip or toothpick. The reset button is recessed and located in the back of your modem. Unplug the modem from the wall jack while pressing the reset button for approximately 30 seconds.
Click on your Start menu, and select the Control Panel. Next, click "Internet and Network," "Network and Sharing Center" and then "Manage Connections."
Right-click on the network adapter and select "Disable." Right-click on the network adapter icon once more and select "Enable."
Type in "http://192.168.1.1" to your Internet browser. Type in the default user name and password for your network. Refer to your modem's manual or access the manufacturer's website to find out the default password. If you are able to access your network using the default user name and password, your computer is reset to factory settings if you created a unique user name and password previously.
