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.
