It take me a while to find out what is wrong with wireless radio then I solve it.
It`s about Launch manager that is not installing correctly on versions higher than XP.
How to use FN and special buttons and function as in win XP:
This steps are for Vista 32/64 and Windows 7 32/64 edition.
1.Download from:http://support.fujitsu-siemens.com/com/support/downloads.html
(the Tools and Utilities - Application - Tools and Utility - AMILO A1650G
Quick Button - Launch Manager)=for windows xp
2.Right click on Launch Manager Setup file.
Open compatibility tab and mark "run in compatibility mode for windows xp (service pack 2)"
Also on privilege level mark "run this program as an administrator".
Then run setup.
Reboot.
After rebooting on systems using 32 version of Windows(Vista or 7)
quick buttons should run as on xp.
For 64 versions do like this:
1.Copy all files from inside the folder where is installed Launch manager.
should be: program files\launch manager to startup folder.
Reboot pc.
Afther reboot on the screen should apear a lot of files with error.
It doesn`t matter now the light for wireless is on and the launch manager is running.
Try fan silent button to see,it`s running.
Go back to startup folder and delete all inside files that are copy before.
Reboot.
Now it`s all there and running.
Tested on Windows 7 Ultimate 64 edition(should be the same on Vista 64).
For Windows 7 (64) most of drivers come via Windows updates.
The latest drivers U can find them on manufaturer sites(ati,realtek,...)
For modem use the xp driver from fujitsu site.
P.S. Don`t forget to enable from bios wireless function(for automatic start).
