MacBook Air 2015 wifi problem O/S Catalina 10.15.4

Catalina 10.15.4. Spoke with Apple 3 times. Now in email assistance with them on this issue. Unusual situation. Faithful Mac user 15+ years. WiFi "disappeared from the MB Air. The wifi icon in the menu bar is faded. Cannot access wifi. No networks show up in "network", only the Bluetooth option. I can access internet via connecting the MB air to iPhone hotspot. My MacBook Pro, 2 iPhones and iPad all connect to wifi with no issues. My other option is to send to Apple. If it is a hardware issue $475+ USD to repair. Suggestions?

How old is the Mac and how much memory?

Stick a USB WiFi dongle in and see if that connects.

This indicates that the problem is with the software rather than the hardware. I assume Apple have gone through your Network settings to ensure that is all set correctly. Could you get hold of a USB to Ethernet adapter and try a wired connection to your router?

Did a wired/usb hot spot and it worked. Was going to reinstall the OS but cannot do it w hotspot.

I was going to suggest an Ethernet cable but I see from here click here that is not an option unless you can get hold of an adapter.

Also see here click here Second paragraph of reply. Did you disable yor onboard wifi to try the usb dongle?
