I had the same issue. Updated to catalina overnight and in the morning wifi was not working. I reinstalled catalina from Recovery again. Now wifi is working even though System Information App still shows (null) for Network -> Wifi entries
After iOS 13 and Mac OS Catalina, it seems that Apple needs to introduce a helper utility to pair the device.
I’m an iOS developer and we use Xcode’s built in utility to pair and unpair devices.
Sometimes the device doesn’t get automatically connected so we have to connect it via a fixed IP address.
Open Xcode (can be downloaded free)
Open devices and ...
I found a workaround which works fine for me.
While connected to the hotspot open a cmd and enter the following commands:
After that, the client gets instantly a correct IP-Adress from the DHCP.
Seems that iOS 13.1.2 Personal Hotspot's DHCP is not working, at least on Win7. What what was done was assigning client IP manually (on the PC)
IP Address: 172.20.10.11

Now is working.
Troubleshoot WIFIONICE MACBOOK (wifi on ice)
sudo killall -HUP mDNSResponder
go to System Preferences > Network > (Select) Wifi > Advanced > DNS to add a sample dns 18.104.22.168

The excerpt from an article:

You can use a direct USB-C to Lightning cable (I used an MFi cable by Aukey). Turn off the iPad's wifi, make sure you are signed in to the same apple ID, have iOS13 and Catalina installed. It is much faster than the wifi connection for me (and I also have less lag on my mac this way).
My Mac kept nagging after configuring a new iPhone. Despite turning WiFi calling on on the Mac, and rebooting, the nags kept re-appearing.
What finally caused a stop was updating my E911 emergency contact on the phone. No more Mac nags!
CONFIGURING EAP-TLS AUTHENTICATION on IOS DEVICES:
I prepared below instructions configuring IOS Clients- both iPads & iPhones- to connect to a MikroTik Router advertising an SSID requiring EAP-TLS authentication.
I've tried to make them as generic as possible. In any event, the process of installing the Certificates into "Profiles" on IOS devices ...
