Now the multimedia buttons don't work, one of these buttons is the power button for the wireless card. There is a package called Launch Manager which includes an executable wbutton.exe which I take to be the software that would power on the wifi if the button were detected.
Windows 7 detects the wifi and of course the diagnostics helpfully say power on the wifi.
I've tracked down various versions of Launch Manager and none of them work - other function key combinations work though to change the volume or screen brightness so it looks like Launch Manager is working.
The bios contains two options for the wifi card: off or last state, so I can't power on the wifi card there.
I contacted Medion and the advice was to remove the wifi card from device manager and try the power button again but that didn't help....
In the meantime I've tried using a USB wifi dongle but its performance is woeful, it drops out every 5 or 10 minutes.
Any ideas much appreciated.
