sudo apt-get install firmware-atheros 
sudo dpkg -i --force-overwrite /var/cache/apt/archives/firmware-atheros_20210315-3_all.deb
sudo apt -f install

This is what worked for me -

Add this line in /etc/apt/sources.list - (choose your text editor ... nano, vim, etc) - I like nano

deb http://httpredir.debian.org/debian/ bullseye main contrib non-free
#deb-src deb http://httpredir.debian.org/debian/ bullseye main contrib non-free

(nano exit and save) - CTRL x
