There isn't a switch on the T42. (I'm using one to write this). the Function (Fn) key toggles the adapters but only if the correct utility is loaded. That is on the lenovo site called 1qkcb9ww or 8jvu12ww. Not sure which controls those features. If Fn+F5 doesn't do it... You otherwise usually get that message when there is a network adapter conflict and sometimes if the driver has become inactive which it does not too often. Try first disabling any other network adapters like Ethernet and maybe even the infrared network adapter though I doubt that could be it. Mine is disabled anyway. Do this in 'Network connections' from control panel for the Ethernet or with Device manager (Systems>hardware>device manager) if you never use a wired connection. If that doesn't help try reinstalling the drivers from the Lenovo site. Andrew L.
