Be extremely cautious with pre-patched kexts because if they bear a lower or identical version than the vanilla kext of /S/L/E, they won't load from /L/E. You can easily verify that by replacing the vanilla copy located as a PlugIn of IO80211Family kext.

 

The DSDT patch is provided in the inventory thread linked in post #2. That's what you should use as a permanent and sustainable solution. The kext patch would likely be required after any update or upgrade. You can trust me on this, I had an AR9285 card in the recent past.

how can I do this DSDT patch?

I understand that I need to add code from that post to DSDT but how?

 

I know how to add PCI id to AirPortAtheros40.kext/Contents/Info.plist, but that doesn't work. This only enable WiFi module, but that's all.

All I get is same as image no.3 in post#1 by richard1994x.

I copied DSDT to Extra folder which you sent me.

Than I also remove AirPortAtheros40.kext from /L/E and /E/E.

Replaced IO80211Family.kext in /S/L/E by another one from other Sierra installation on the same dell model but with different WiFi modul.

Than repaired kext:

sudo chmod -Rf 755 /S*/L*/E*

sudo chown -Rf 0:0 /S*/L*/E*

sudo touch -f /S*/L*/E*

sudo kextcache -Boot -U /

 

restart PC but wifi still can't find any available SSID's

only ethernet is working :(
