Hi there, does it work on newer kernel or older kernel， or doesn't work on many version.
And do you have another chipset work?
such problem often can't solve in short time, you'd better find another plan,such as eth or a usb net work card.
deepin I have two laptops with same pci wifi cards. rtl 8821ce. I have two different kernels on those laptops (but deepin os 20.2.3 is on both). One laptop has kernel 5.12 and other one 5.10 (don't ask me why I installed different kernels, I guess because 5.10 is called stable) lsmod showed that rtw88 is used and I read on google that linux started to support realtek chips with kernel above >5.9... so, I am now partialy happy... I would like that this new module works on kernel 5.10 like on 5.12 and I am not sure how to reinstall all again to kernel 5.12 but to keep settings...Thank you for support and great OS. I really like deepinOS...
deepin I solved my problem by:
sudo apt install linux-image-deepin-stable-amd64 linux-headers-deepin-stable-amd64
I switched to kernel 5.12 and everything is working!!! Thx
Moderators please close this as solved

The settings menu needs to be translated into Russian.
