Hi, Maureen! 

I don't mean to butt in, but just wanted to give you some
reassurance/encouragement.  The wireless adapter you have certainly
should work (barring a hardware problem).  I have the same exact one,
and it works fine!  

I am running Debian 12 (Bookworm) now, but the setup was upgraded in
2023-06 from Debian 11 (Bullseye).  It worked fine on Debian 11
(Bullseye), at least under Debian 11.6.

. . . 
rtw88_core            192512  2 rtw88_pci,rtw88_8821c
. . . 

And firmware-realtek is installed.

>From sudo aptitude show firmware-realtek:

Description: Binary firmware for Realtek wired/wifi/BT adapters
 This package contains the binary firmware for Realtek Ethernet, wifi
and Bluetooth adapters
 supported by various drivers. 
 
 Contents: 
. . . 
* Realtek RTL8821C Bluetooth config (rtl_bt/rtl8821c_config.bin,
rtl_bt/rtl8821a_config.bin) 
 * Realtek RTL8821C Bluetooth firmware (rtl_bt/rtl8821c_fw.bin) 
. . . 

However, I am puzzled as to why aptitude says firmware-realtek is:
State: installed
Automatically installed: no
since I never installed it manually, the wireless adapter just worked
"right out of the box".

Note: Debian 11 was originally installed using using the Debian 11.6
"nonfree" iso.  

Hope this helps. Otherwise, feel free to disregard.
