I have the same problem as posted in this previously posted question: tp-link ac600 ubuntu not working after upgrade to 19.10.

I too had used the solution as posted earlier by Jeremy31 to get the wifi adapter working on Ubuntu 18.04. I then reapplied that "Jeremy31 solution" each time the Ubuntu kernel was updated to get the wifi adapter reworking again. That methodology worked fine up through all kernel upgrades until I recently upgraded my laptop (Lenovo G500S) to Ubuntu 19.10. With the "Jeremy31 solution" no longer working for me, I have googled as best I can, but have been woefully unsuccessful in finding an alternative solution that will allow me to re-employ my wifi adapter in 19.10.

Does anyone have any suggestion, or suggestions, for helping to get my wifi adapter working again?

Thank you very much in advance for any help you may be able to offer.

This version compiles perfectly on my 19.10 machine using kernel version 5.3.0-23. The compiled driver covers your device:

$ modinfo 88XXau.ko | grep 011E
alias:          usb:v2357p011Ed*dc*dsc*dp*ic*isc*ip*in*

Please do:

git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo ./dkms-install.sh
sudo modprobe 88XXau

Your wireless should now be working.

I tried to comment on chili555's answer, but I don't have enough reputation. So here is the comment: https://github.com/aircrack-ng/rtl8812au.git does not contain the file dkms-install.sh. But the repository https://github.com/jeremyb31/rtl8812au-1.git does have this file (I tried that solution first after reading it here, but it didn't work for me).

So I copied the two files dkms-install.sh and dkms-remove.sh into rtl8812au directory, ran dkms-remove.sh first and then dkms-install.sh.They worked perfectly. After that, I ran the modprobe command from above, and my adapter started working

Hope this helps somebody
