it’s the same old same old problem X-D
WARNING! BACKUP ALL DATA BEFORE TRYING THIS EXPERIMENTAL WAY OF GETTING REALTEK WIFI ADAPTERS TO WORK FOR DEBIAN 13 😀
strange enough, there is no apt package (yet)
hostnamectl Operating System: Debian GNU/Linux trixie/sid Kernel: Linux 6.12.12-amd64 Architecture: x86-64 Hardware Vendor: Gigabyte Technology Co., Ltd. su - root apt update apt search firmware-realtek # nothing # this is because # 1) there are (unfortunately) no open source drives from realtek for there wifi adatpers (shame on all of em) # 2) someone renamed non-free repository to non-free-firmware (seriously, why?) # so if user got non-free in the /etc/apt/sources.list sed -i 's/non-free/non-free-firmware/g' /etc/apt/sources.list # so it looks like #Stable deb http://deb.debian.org/debian trixie main contrib non-free-firmware deb-src http://deb.debian.org/debian trixie main contrib non-free-firmware deb http://deb.debian.org/debian-security/ trixie-security main contrib non-free-firmware deb-src http://deb.debian.org/debian-security/ trixie-security main contrib non-free-firmware deb http://deb.debian.org/debian trixie-updates main contrib non-free-firmware deb-src http://deb.debian.org/debian trixie-updates main contrib non-free-firmware # Testing deb http://ftp.us.debian.org/debian/ testing main contrib non-free-firmware deb-src http://ftp.us.debian.org/debian/ testing main contrib non-free-firmware apt update apt search firmware-realtek # found it? great install apt install firmware-realtek
# still nothing? ok manual mode # so using version from debian 12, manual install wget http://ftp.ch.debian.org/debian/pool/non-free-firmware/f/firmware-nonfree/firmware-realtek_20241210-1_all.deb # sha512sum: ef4142f314b9730106ae25ec9442a5a80f86e2f371b16da366a16a709c31075096e402ab52733b0cc8d725814b08722e366a234e584a4babc0ec979c4dc1df85 dpkg -i firmware-realtek_20241210-1_all.deb
try a reboot afterwards
after that at least 1x out of 3x tested realtek adapters THE EDIMAX (see here and here) works 😀
also known as Edimax N300 (search ebay)
