My laptop worked great all the time with the wireless connection to the WLAN. But since 3 days it says that I can only use Ethernet and I can't press the on and off switch for the flight mode. My laptop doesn't find any networks, whether it's from my neighbors or my own. I have Windows 10 and it worked all the time, but now I can only use my laptop with the LAN cable. Can someone help me how I can get the wireless connection back?
I strongly suspect that your WLAN module went hops.
Could the tow top be bluetooth? If so, does it still work?
Either you send it in for repair, but have a KVO done beforehand, or you buy a USB Wi-Fi stick
