IOW, does firmware=N/A merely mean Not Applicable, because the device doesn't need or load it. > multicast=yes wireless=IEEE 802.11 > resources: irq:135 ioport:3000(size=256) > memory:70800000-7080ffff > . . . > > from lsmod: > . . . > rtw88_8821c 90112 1 rtw88_8821ce > 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 > Version: 20230210-5 > State: installed > Automatically installed: no > Multi-Arch: foreign > Priority: optional > Section: non-free-firmware/kernel > Maintainer: Debian Kernel Team <debian-ker...@lists.debian.org> > Architecture: all > Uncompressed Size: 7,046 k > Suggests: initramfs-tools > 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. As you used the nonfree/firmare ISO, the d-i detected the wifi device and installed the appropriate firmware, included on the ISO, to make it work. This typically happens just before installation-report and popularity-contest, and the latter's question. The package appears to be "manual" rather than "auto" because AIUI the d-i is installing it, not APT. I have no idea how the OP installed their system, whether they did it through wifi, and which ISO they used. (Nor what "the /same/ problems" are in the Subject line). Even if the original installation was done with wifi, the fate that befalls the wifi configuration depends on the choices made in the task selector. My beef has always been that choosing a non-DE installation, as I do, results in the wifi configuration being removed moments before the d-i reboots. Cheers, David.
