Hi so i logged back on today to find out my networking card isn’t working.
Although the card works fine outside of Ubuntu fine. Its just in Ubuntu it isn’t working
I’ve tried reinstalling the 8821CE drivers and the network manager and tried restarting.
But it isn’t fixing the problem, so i figure i join these forums and give this a shot.
However, i did read to give out logs, so i have done so here: https://pastebin.com/gWNN33AU
Please post URL from terminal for sudo dmesg | grep 8821 |nc termbin.com 9999
Seems these devices are struggling lately
sorry not really able to do that. that either requires me to have a long ethernet cable which would be running to the other side of my house. or to use usb internet tethering, for hotspot that does not come with my phone plan.
the pastebin link is all i can give. as i have to use windows to post this message and the link.
sudo dmesg | grep 8821 > 8821.txt Then copy the 8821.txt file to a USB drive and transfer to Windows to post?

Sorry fairly new to this 
Do you know why /etc/NetworkManager/conf.d/wifi_backend.conf is there? And what result for mokutil --sb

No i do not know why? Did the operating system make it? 
and the result.
mokutil --sb
SecureBoot disabled
Platform is in Setup Mode
i have not from the time of building my computer have ever ever enabled secureboot and i can suggest the fact for months on end it previously has been working fine. i would not say its an issue. something else is wrong with it.
Can you boot into 6.8.0-49 kernel? See if wifi works there?
afaik the only things i see is Ubuntu going to the normal option gets me to Ubuntu, with Linux 6.8.0-51-generic
and in the grub menu i also see
ubuntu, with Linux 6.8.0-51-generic
ubuntu, with Linux 6.8.0-51-generic (recovery mode)
ubuntu, with Linux 6.8.0-50-generic
ubuntu, with Linux 6.8.0-50-generic (recovery mode)
Try the 6.8.0-50-generic option, not recovery mode
in that kernel it doesn’t even show the wifi option altogether. it just shows the connections panel.
Mine is exactly this one, RTL8821Ce, and it’s working.
what does the command:
dkms status
return ?
there is a driver in the kernel for this card (rtw88_8821ce) that should just work, if you installed a dkms driver for it alongside this might cause clashes …
i guess i have done did that. the command shows me
dkms status
rtl8821ce/v5.5.2_34066.20200325, 6.8.0-51-generic, x86_64: installed
don’t know what to do from here.
