I have a laptop with a wifi card that needs proprietary drivers (and no ethernet). The Debian 10 installer (debian-10.0.0-amd64-xfce-CD-1.iso) failed to automatically detect the driver (*.ucode file) that I had on a USB, so I continued the installation without internet. I logged in and copied the ucode to /lib/firmware and now my wifi card seems to be working ("ip a" will list my wifi card)
I'm trying to connect to wifi with WPA security. The problem is that it appears I do not have wpa_supplicant installed (nor iwconfig, nmcli, connman or etc). Every guide or QA I've found (eg this) assumes wpa_supplicant/wpa_passphrase/etc is already installed.
So, how do you connect to WPA wifi in this situation?
