What is the problem?
I cannot connect to a wireless network.
What did you already try to solve it?
I checked /etc/network/interfaces.d and it looks empty? I upgraded to an rpi noir camera but octoprint didn't recognize the camera (even though the regular rpi camera worked). I read somewhere to try to do an rpi-update, and after that, wlan0 isn't even showing up when I do ifconfig. When I use sudo raspi-config, it says "no wireless interface found". Before I did the rpi-update, it was connecting just fine to the wireless connection, so rpi-update must have erased some settings?
Logs (syslog, dmesg, ... no logs, no support)
I can't connect to the internet to provide these logs to you. If I can get connectivity, I will supply them if needed. Tell me which ones and I might have to write them to the rpi card and then move them manually to the PC I'm using to type this.
