This is not first time I face such problem, so I tried to solve it in usual way: uninstalled and reinstalled Hotkey package and drivers (Power Management driver and WiFi), tried several different versions of drivers and Hotkey - all to no success. Whatever I was doing, only BT was seen in Fn+F5.
FinallyI ended up reverse-engineering Hotkey, and got quite unexpected result: it simply doesn't know WiFi driver present on the notebook. Hotkey package (namely, TpFnF5.exe file which creates Fn+F5 window) has a hard-coded list of known adpater Hardware IDs. Intel WiFi Link 5150 present on the notebook has ID VEN_8086&DEV_423D&SUBSYS_13168086, while closest match in the list was VEN_8086&DEV_423D&SUBSYS_13118086. As an experiment, I've patched TpFnF5.exe to replace "13118086" with "13168086", and voila - WiFi appears in Fn+F5, and can be switched on and off!
Ok, thereason is found, but how all other identical machines work?! I checked another notebook, and found the difference: it had Access Connections installed, while the troubled machine had only Hotkey but not AC. It turns out that Access Connections has it's own executable for Fn+F5 dialog, AcFnF5.exe. When you press Fn+F5 with AC installed,
