Function Key not working, how to turn on wifi on Windows 7

HP 250 G6
Microsoft Windows 7 (64-bit)



Sorry for long and 

After having struggled with Windows 10 for 3 weeks, the system still used 100% of CPU for some internal work not leaving user chance to do anything.I came into conclusion that this system is to heavy for this not very powerful machine.

I downgraded os system to Windows 7 Proffesional, from my MSDN Subscription, deleting factory installed Win 10.


I installed all possible to get win 7 drivers, as adviced on one of the forum posts for resolving key poblems,



(video driver 75508 did not work, 75629 was not available)


I resolved nearly all problems (I could live with standard video) but one with not working wifi is show stopper.

All drivers for wifi are installed and seems to work ok, I can see adapter settings for wifi connections but can't see any network available even sitting oposite my router. (I can connect by cable, LAN driver works ok)

I think the reason for issue with wifi is functional keys problem that I can't turm wifi on by pressing F12.

Investigationg wifi connection problem I get the message that I have to turn the wifi switch on. I can see that for this machine it is possible only with functional keys. 

Unfortunatelly, brightness and plane mode functional keys do not work.


Please give me a solution how to solve one of the following problems:


- how to make all function keys working, both brightness and wifi keys

-or, how to turn on wifi other way. e.g. by running command in windows powershell

-or,  how to have wifi turned on on computer start and never turned off


This is critical for me to have wifi running, I can't use cable in location that I am going to use this computer.

Please help.
