Hello,

RTL8821AE and RT8821CE are two different chips, albeit with similar features, 
the latter improves upon the former:
 https://www.realtek.com/en/products/communications-network-ics/item/rtl8821ae
 https://www.realtek.com/en/products/communications-network-ics/item/rtl8821ce

there is a RTL8821AE branch in the mainline kernel source tree and at least up 
to 5.8, there is none for RTL8821CE.

I have had a RTL8821CE based card in my laptop (since replaced by an Intel 
AX200) and was building its driver from the above mentionned site (Pinho): I 
don't remember the module being rtl8821ae instead of rtl8821ce (but perhaps 
have I forgotten)

I have (almost) ready mylaptop, but there are still a few details to

wifi(https://github.com/tomaspinho/rtl8821ce 
) but it is not loaded during 
the boot process. The generated module is "rtl8821ae.ko" (not 
"rtl8821ce.ko") but apparently it works fine (have to test it thoroughly).


When I first tried to load rtl8821CE the system said that could not be 
find at /lib/modules/5.8... so I searched for it manually and found 
rtl8821AE at /lib/modules/5.8.../kernel/drivers/net/wireless and 
loaded manually "modprobe rtl8821ae", then the wifi device appeared 
and worked.


My question is: How can I load automatically the driver? Perhaps the 
kernel detects RTL8821CE and expects for rtl8821ce.ko... Is there some 
way to load it explicitly maybe adding rtl8821ae.ko to a list of 
modules to load?


Thanks again for your help and patience

Is there a reason for using an external driver? Kernel module for your 
NIC is already provided by stable kernel image. You've probably just 
missing a firmware. [1]
Have you tried to install "firmware-realtek" package from non-free 
section of official Debian "buster" or "buster-backports" repo?
