This is not as much a cry for help as it is also a rant to vent frustration....with the Debian installation process.
I'm trying to set up a headless machine; so just SSH, no GUI and after multiple tries and searching the interweb I can't get the wireless configuration work across reboots.
During the Debian 10 installation process the wireless card (wlp2s0 - Intel) is detected and functioning properly up to the moment one has to pull out the installation media and reboot. As you can tell, I'm not using the LAN NIC to do the installation.
After the fresh installation, it seems that the WLAN drivers are installed, but the NIC is not UP and doesn't get an IP address from DHCP.
Manually configuring (wpa_supplicant) does make it work, but not across reboots.
I've tried both the regular Debian 10 installation (non-free drivers on another drive) and the image with the non-free drivers included.
The weird thing is that installing WITH the GUI the WLAN NIC is configured and functioning properly!
Why is the CLI install not properly picking up and saving the wireless config during installation time?
