I reformat my fujitsu simens amilo pro laptop thinking that it might reset the setting but still the wireless capability is turn off. I try to use different wireless adapter but still it won't work. I think the alphanumeric key is not functioning.
So the hardware button for the wireless is not working? Check the fujitsu website for a driver. I had a similar problem with my laptop after an OS upgrade. Once I got the driver installed the buttons worked again. Could you provide a model number for the laptop? I see at least three different versions.
