hi there,

try Fn+F5..

Hope that helps!

There is no hardware switch wireless. Just hold Fn and press F5. It would brings up a menu that allows you to turn Bluetooth on/off, WiFi on/off or both.

Hope this helps

You have to press the Fn + F5 to turn the wireless on.

For most IBM ThinkPads, the shortcut key to activate wireless is Fn+F5. I am not so sure about this model, but you can try. If this doesn't help, check the Device Manager and make sure it's shown on the devices lists. By default wireless is activated once the driver is installed on almost all IBM ThinkPads. You problem could be driver corrupted or missing. The best resolution is reinstalling the driver so that it'll not fail. If the problem persists, then it could also be your wireless card failure. You better check it twice.

Good luck.

Thanks for using FixYa.

If you have ThinkVantage Access Connections running (icon in the system tray), click on it and select Power On Wireless Radio. Another way is to press the blue Fn key and the F5 key. (The F5 key should show a computer with wireless lines coming out of it.)

Check that the correct device driver is installed using the device manager via the control panel.

There's no hardware switch to activate and deactivate the wireless networking, but pressing Fn and F5 brings up a menu that allows you to turn Bluetooth on/off, WiFi on/off or both. It seems like IBM isn't satisfied with standard toggle buttons like other notebook manufacturers - even pressing the Fn and F7 buttons to switch between internal and external screens, brings up a menu with multiple display settings and resolutions.
Hope this helps,
