I have a problem with a G550 laptop, running windows 7.
No matter what I do, wifi will not work. When the manual switch is set to wifi on and i press fn+f5, nothing happens.
The wifi card is recognized in windows, i have the latest drivers from lenovo support page and so on.
I have tried literary everything, including windows reinstall and still nothing.
When I run windows diagnostics it also says "wifi options (or something like that) are not enabled" and i tried with readycomm which says the same thing.
Is this actually some kind of a hardware defect?
Solved! Go to Solution.

I already tried that
It doesn't do anything (even if i try pressing the fn+f5 after setting this switch)
I also checked in BIOS and the card is 100% on.

Readycomm wasn't installed when this problem occurred, I installed it later, desperate for anything
When I uninstalled it the wifi still didn't work, but I will try reinstalling the power management and I'll report back
During my fiddling with the computer I did never see such a window like that above.
Unfortunately, it will take some time for me to try this out, since the g550 is my GFs and I don't have acces to it ATM

I uninstalled Energy management, restarted and installed Energy management again (the latest version from leonovo page).
At this point the wifi started working.
Then I uninstalled all the unnecessary drivers (for wireless and regular LAN adapter etc. - I think i manually installed only the ones for GPU and chipset) and also energy management.
Restarted again and let windows do it's thing.
It works great since then.
