Hmm, from the EFI files, I'll assume you are referring to E7440 that you have another thread opened for.
In that case, it should have an Intel Ethernet and Intel Wifi.
For the Ethernet, upgrade the IntelMausiEthernet.kext to the latest version or switch to AppleIntelE1000e.kext
For Intel wifi, it's not supported, switch to DW1510 for Wifi only or DW1550 for Wifi/BT combo.
You'll need to restore 2 kexts from Mojave since the chipset are not longer supported in Catalina.
IO80211Family.kext & IO80211FamilyV2.kext to /L/E
