[SOLVED] Wi-Fi not working - Sierra 10.12.6 on E7450 with 840m


Recommended Posts

I just noticed that I have no Wi-Fi at all. In System Presences / Network I can only see Ethernet and BlueTooth.


I tried to replace FakePCIID_Broadcom_WiFi and FakePCIID in /Library/Extensions with new ones from RehabMan-FakePCIID-2017-0527.zip and to fix permissions and rebuild cacse as instructed here



There is no change. I guess I already had same files since I used updated bootpack.
