once type ls in whatever directory you are executing the make command and see if there is a README. And check out if there is some steps.For me once this type of issue happened.

@xtrator
I had the same issue but following these steps helped: https://askubuntu.com/a/1238017/993667

@Vinceent
Is it alright if I install a rtl8723de driver even though my wireless device is rtl8821ae? asking truthfully

@Vinceent
Alright I grew some balls and I've recovered my wifi strength. although I am still having the lag spikes from time to time.
