Hi, I had the same problem. Kernel Panic every time I connected to the ethernet adapter.
I was able to solve creating a new Wi-Fi configuration as described in the article on OSXDaily: how-fix-macos-big-sur-wifi-issues


Temporarily disable Wi-Fi on your Mac by clicking on the Control Center icon in the menu bar at the top-right corner of your screen.
Next, open Finder and head over to an easily accessible location. Make a new folder here and use a suitable name. Once you’re done, click on “Go” from the menu bar and choose “Go to Folder” from the dropdown menu to proceed.
This should bring up a tiny window on your screen where you’ll be able to enter the path. Copy/Paste the following path and click on “Go”.
/Library/Preferences/SystemConfiguration/
Next, find and select the following files in the SystemConfiguration folder.
“NetworkInterfaces.plist”
“com.apple.wifi.message-tracer.plist”
“com.apple.airport.preferences.plist”
“preferences.plist”
Once all these files are selected, move them to the new folder you created. Now, restart your Mac and then re-enable Wi-Fi from the macOS Control Center.
Try opening Safari and see if you’re able to browse the web without any issues. Wireless connectivity should be working fine by now. 

I hope this can help you.
