LyonLeBrun Posted September 14, 2020 Author Share Posted September 14, 2020 What a relief. It's working. (I suspect the Wi-fi switch made the difference). Here's what I did... I rebooted and checked the BIOS: Wireless Switch there are four checkboxes: WWAN, WiGig, WLAN, Bluetooth® - all are checked Wireless Device Enable: Three checkboxes: WWAN, Bluetooth®, WLAN/WiGig - all are checked. The switch on the side *was* showing red. I switched it back (on, not red). After a reboot, wireless started up, just as it's supposed to. To summarize this incredibly long journey (with huge thanks to you), these are the steps that seem to have mattered: The Solution for Catalina on Dell Latitude E7440 laptop with AzureWave AW-CE123H wireless card: Use the OpenCore EFI folder for Dell Latitude E7440 (https://osxlatitude.com/forums/topic/13155-solved-e7440-no-usb-port-working-with-opencore/?do=findComment&comment=101900) Replace that original config.plist with the one from a few posts ago (https://osxlatitude.com/applications/core/interface/file/attachment.php?id=28462) Ensure all the Wireless boxes are checked in the BIOS Install Catalina 10.15.6 - it seems OK with the AzureWave card Since no kext's were replaced, there was so no need to repair permission or rebuild cache TURN ON WIFI SWITCH on the right side of the laptop I used these OpenCore-safe tools: MountEFI and ProperTree and IORegistryExplorer when needed.
