Hello guys. Followed the great guide for the Dell Latitude 3490 here but on my Laditude 3590. Installation was a success but even as my Latitude 3590 uses the Dell DW1820 which should work only the Bluetooth part works. Don't have any wireless module in the Network section. Already tested the DW1820 by installing Windows to see if the module is showing up there. So in Windows the wireless module is fully functional (even connected the a WLAN Network and downloaded some stuff). I have the feeling that some kexts don't get loaded or are not active. Usually the green dot at the kext indicates if it is active, or ? Other issue is the really terrible touchpad. The pointer is sometimes jumping around like a drunken frog. As there was absolutely no change after adding the kexts i guess the kexts aren't loaded here too. Already tried to fix permissions (manually), even with Kext Wizard (additional installation of the kexts and fix permission)
