I am trying to use a live ISO of Ubuntu 23.04 on a laptop that requires proprietary WiFi drivers. My networking card is detected correctly in Software Center and I am able to enable the proprietary drivers, but I still don't have any WiFi networks showing up in my network settings. Normally, you have to reboot after installing the proprietary drivers in order for the desktop environment to detect them, but I cannot do this because I am in a live environment.

Is it possible to use nonfree WiFi drivers in a live environment? E.g. is there a systemd command I can use to prompt the system to rescan for WiFi hardware?

Yes, you can install software, drivers, firmware, etc. in a live environment.

First, install the probable correct driver and remove the incorrect driver:

sudo apt purge bcmwl-kernel-source
sudo apt update
sudo apt install firmware-b43-installer

Unload and reload the driver to get the driver b43 to recognize and use the newly installed firmware:

sudo modprobe -r b43
sudo modprobe b43

You should be all set.
