Lenovo G510 B / G Series :: No Wireless And Wired Internet Access After Going Into Flight Mode?

Till now, my G510 with Win7 64 bit worked perfectly but after going into flight mode and coming back, it no longer recognizes any internet sources, wired or wireless.

Windows troubleshooter says I need to 'turn on wireless capability'. I don't see a wireless hardware switch anywhere on the laptop, fn+f5 does nothing and in the panel for the flightmode, only bluetooth appears (which I can also activate). The device manger says all of the network devices are working normally. I tried reinstalling the latest drivers from Lenovo, but that didn't do anything either. The Windows Mobility Center says that the wireless is turned off, but the 'turn wireless on' button is greyed out and is not able to be clicked.
 
In an earlier post, it was suggested to check if in "services.msc" the "WLAN AutoConfig"  function is activated which is in my case true. WIFI is also activated in the BIOS.
 
Last thing I tried, was to bring with windows recovery the system back into a state where everything worked fine but also that did not work.
