Could this be part of the problem.  I have no wifi so that is part of
the problem.  This is Disabled so how do I enable it?
Thank you guys for being patient with this old lady..

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.


From my current setup:


lshw:

                 resources: irq:135 ioport:3000(size=256)

from lsmod:

rtw88_pci              28672  1 rtw88_8821ce
. . .
rtw88_core            192512  2 rtw88_pci,rtw88_8821c
. . .

And firmware-realtek is installed.


From sudo aptitude show firmware-realtek:

Package: firmware-realtek

State: installed

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.
For what it's worth, I lost my wifi connection (via a USB Realtek adaptor) a couple of days ago and finally woke up enough to swap the USB adaptor to another USB port. So no diagnosis, but it works. Maybe this will do the same for you, Maureen. Oh! and I re-installed the realtek-firmware package, but I suspect that is a red herring.
