When I tried to connect WiFi with Raspbian Strech Lite, “Could not communicate with wpa_supplicant”
Raspberry PI zero W has a new Raspbian distribution Strech.
Since it was so hard, I decided to try it, and I couldn’t connect to the wireless LAN for some reason when connecting from USB to SSH.
Rewriting wpa_supplicant.conf doesn’t seem to connect, so when trying to access the NetWorker settings from raspi-config, the title, could not communicate with wpa_supplicant error and here was an error running option N2 Wi-fi Error returned.
When I looked lightly, I also found an article that caused the lack of country code,
but I did not feel that I was reading conf in the first place, so I thought that the device was disabled, I did sudo ifup wlan0, ifup: unknown interface wlan0 .
After all wlan0 seems to be disabled.
I referred to this official forum.
sudo vim /etc/network/interfaces
and, you should write in bottom
allow-hotplug wlan0 iface wlan0 inet manual wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
This will allow wlan at startup. afterwards,
sudo systemctl enable wpa_supplicant.service
sudo reboot now
Restart Raspi to complete.
Now, no error is returned when opening the network setting from raspi-config.
If you have a problem with the same symptoms, we would appreciate it if you could refer to it.
