I seriously doubt that. udev is part of systemd now and it seems crazy Debian would maintain old code like that. With a quick look at the the patches Debian applies to udev there are six but none of them seem relevant to firmware loading.

What I'm saying is modprobe doesn't load firmware and udev does since that was the observed behavior here. The OP in this very thread installed firmware and modprobed the driver but wifi device still didn't work. > How do you load firmware manually, please? I don't know, feel free look it up and share. All I know there was once a specific command to load fw for an old 3G modem I have in an old laptop but today that seems to happen automatically.

How do you load firmware manually, please? I've always assumed that each driver (module) knows how to load its own firmware into its own hardware in its own special way. I've never tried going back and forth, but even if the firmware remains in the device, there's little to be gained by not reloading it, and a lot more to be gained by refreshing it (like updating it). Cheers, David.

Now I can send this message from Debian. I saw the network interface number 4 [1] after installing and running the firmware only. Then, dmesg showed that last line that told me the "wlan0" (i.e. the wireless device) was instead "wlx000d81af0249". So, I opened Wicd one more time to see if something happened, I clicked on preferences and saw that the wireless network interface field was empty. I wondered what would happen if I wrote wlx000d81af0249 [1] there. So I did it and boom! It works! I wonder why Wicd doesn't detect the wireless interface automatically. Was it designed to be configured manually or is it a bug? Anyway, is there some way to automate this? I saw there was that command "ip link set up" but it doesn't make Wicd recognize the interface automatically.

I don't think modprobe loads firmware. Alternatively you can just unplug and plug the adapter after installing the firmware. But if you did this and it still doesn't work I'm pretty much out of ideas. Does dmesg report anything relevant to network or realtek? For example I get this when my new system boots: r8169 :03:00.0: firmware: direct-loading firmware rtl_nic/rtl8125b-2.fw

How to manually install WiFi firmware on Debian Live?
Hello. I tried to make a "Realtek RTL8191SU Wireless LAN 802.11n USB 2.0 Network Adapter" work on Debian 10 Live with LXDE, but I couldn't. Here is what I already have tried: 1-. Downloaded package firmware-realtek from package.debian.org. 2-. Booted Debian Live. 3-. Copied package from hard disk to the desktop (apt complains when I load it directly). 4-. Executed: sudo apt install firmware-realtek 5-. Executed: sudo depmod -a 6-. Executed: sudo modprobe r8712u Then, Wicd didn't show anything. I ran udevadm, I don't remember how, to see if the USB WiFi adapter was detected; it was and also the module r8712u was loaded for it. I need some help here, please. I don't want to use a non-free firmware live image. Thanks.
