My Realtek USB Wifi adapter used to work fine till a few weeks ago. Today I wanted to try it out but as soon as I plug it in I was getting errors in syslog and dmesg for mismatch on the version magic.
Here are the errors from dmesg
[275369.999797] usb 1-5: Product: Edimax AC1750 USB

How can I change the version magic to be 4.18.0-15 or have it work without changing it ?
sudo modprobe 8814au
