I recently updated an Acer TravelMate 7730 from Windows Vista to Windows 10.
After the update I noticed the WiFi button was not working and there was no network available. When troubleshooting the adapter, Windows stated that ‘The device cannot find enough free resources that it can use. You need to disable one of the other devices on the system.’.
In Device Manager (start, run -> devmgmt.msc) I disabled the PCMCIA adapter and everything worked great. Who knew that actually doing what the exception stated could solve the problem :-).
