System and Network configuration • Debian 12 Network configuration problem

$

Last year I replaced my Ubuntu install on my laptop with Debian 12. I recently modified my home network, and can't find the right place to change my network configuration.

I am using a cellular network box assigned to ip 192.168.12.1 and have a printer configured at 192.168.12.123 using a wired interface to the wireless box.
I added a mesh network which is functioning as 192.168.68.1 and uses 192.168.12.1 as the gateway to reach the internet.

Before I added the mesh device my laptop configured the ip address in the 192.168.12.0/24 address range and printed to my printer. When I added the mesh my laptop automatically switched to the mesh network, ip address range 192.168.68.0/24, and will connect to the internet, but no longer sees the printer.

inxi -N shows the wireless adapter as

Code:

Realtek RTL8821CE 802.11ac PCIe Wireless Network Adapter    driver: rtl8821ce
lspci shows the adapter as

Code:

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter
When I click on Settings -> WIFI the system reports "No WIFI adapter found" at the bottom of the popup window. I can not configure the adapter at all, even though my laptop is currently connected to the internet by WIFI.

I have tried using various tools to configure the wireless network which don't give any errors, show the network as changed, but still don't function any differently than before I made changes. I have forgotten what method I used to configure networking originally, though I know that I used the command line because GUI tools won't let me see the adapter. all the GUI tools I have tried simply state that no WIFI adapter is present even though it is functioning.

If there is any additional information needed that I haven't provided, provide the command to produce the information and I'll provide it as soon as I can.
