Random disconnects and DNS issues
Wifi seems to work for awhile after fresh reinstall. But then will diaconnect at random before finally not working at all.

This happens after fresh install and using the remove script. I've tried just about everything I can think of and every troubleshooting thread I could find I have tried. Nothing changes. Anybody know the solution?
Have you tried reading that make.log mentioned by the error message? It contains the information you need.
(Why are bits missing from the error message? Why do you have a driver for some RTL8723 chip? It won't help with RTL8821CE.)
These are very good questions I took some bits out of the error messages that repeated themselves. Guess I will edit them back in. You know I have no idea why that driver downloaded. I cloned the rtl8821ce and that one came up when I started the install. How should I go about a clean install again? Maybe purge everything like apt purge rtl** ???
I've been trying to get jt to work for a week now. Missing all kinds of work.

If you installed it with apt, remove with apt. I don't know the exact command for that. But if you installed it with dkms, remove it with dkms. apt and dkms both have manuals where you can find instructions.
I installed wIth git/dkms and apt. I have apt purged and deleted all real-tek anything from my system and used dkms-remove.sh. I am now trying to use the rtl8821ce git repo that I have cloned to reinstall.
Supposedly I need to edit the makefile so that CC=gcc-8 so im working on getting that setup without internet. And of course my usb sticks will not read by my phone. But thats another issue will report when I make progress.

I installed wIth git and apt. I have apt purged and deleted all real-tek anything from my system.ans am.now trying to use the rtl8821cr git repo that i have cloned to reinstall
Supposedly i need to edit the makefile so that CC=gcc-8 so im working on getting that setup without internet. And of course my usb sticks will not read by my phone. But thats another issue will report when I make progress.
Still not able to get internet. Reinstalled to start fresh. Now not connecting at all.
Finally fixed this myself. Not sure if I know exactly what I did that worked but I started with a fresjh install. Reinstalled all dependencies (linux headers, build essential, etc) using a USB stick or apt-getoffline. I then used rtl8821ce offline installer. And reinstalled it. I tool everything off of my blacklist.conf though so I may just be using the driver that came with the computer but at least it works some of the time.
