Re: How to load new firmware?
Lee,
I do not have a solution for you, but as you likely found via Internet searches, you are not alone in having issues with this Realtek device/driver.
Like you suggested, I too once installed Linux Mint Ubuntu to a laptop to get over hardware issues.
Hopefully the Realtek driver developers will rectify the issue.
All I can suggest is to try backports to get the latest Debian package (but I saw that others have already suggested this):
If backports is not in your apt sources, then add the following lines:
# nano /etc/apt/sources.list
# bookworm-backports, previously on backports.debian.org
deb https://deb.debian.org/debian/ bookworm-backports main contrib non-free non-free-firmware
deb-src https://deb.debian.org/debian/ bookworm-backports main contrib non-free non-free-firmware
# apt install -t bookworm-backports firmware-realtek
# export PATH=$PATH:/usr/sbin
# update-initramfs -u
# systemctl reboot
However if the Debian backports realtek network driver version is still currently faulty, then this will not solve your network issues.

Wifi keeps disconnecting. Using rtw_8822ce
"It seems you have done quite a bit of searching.
What you may not have noted is that there are several threads here about problems with the rtw_8822ce driver and the cards it supports (poorly it seems) in linux.
Most seem to have replaced that card for a fix.
I would strongly suggest that you either replace that card or get a second card (maybe even a usb dongle) that is better supported so you do not have to fight with the realtek issues."
