Error: Could not connect to wpa_supplicant
- First, I did a full upgrade. This broke what wifi networking I did achieve
sudo apt update
sudo apt full-upgrade
- Connect to ethernet port somewhere. I had to do this
- Use the Mr Engman drivers to get my wifi dongle working (this assumes you’re logged in as pi)
wget http://downloads.fars-robotics.net/wifi-drivers/install-wifi
sudo chmod u+x install-wifi
sudo /home/pi/install-wifi
- Add entries to /etc/network/interfaces
auto wlan0
iface wlan0 inet manual
pre-up wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B

UPD: but better to use this script: http://downloads.fars-robotics.net/wifi-drivers/install-wifi
