How to Activate the Wi-Fi in a Lenovo ThinkPad R61
The Lenovo ThinkPad R61 comes with built-in wireless networking that you can toggle on and off. You may need to toggle the wireless off when you are traveling, or when you need to save battery life. The wireless will not work until you toggle it back on, so you need to do that to allow Windows to scan for and connect to the wireless networks around you.
Position the Lenovo ThinkPad R61 so that the front faces you.
Locate the wireless switch along the front side of the laptop case.
Slide the wireless switch so that the wireless capabilities are activated. The switch has a small wireless icon by it so you know it is the proper switch for Wi-Fi.
