I am running into this issue where I have to run the same command every single time and I need to constantly have the window where I ran the command running to make sure the WiFi is connected.

sudo killall wpa_supplicant
sudo wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0

Using the network settings does not work.

Details about my device:

PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"

to me it is broke on every raspberry pi 4 qty(4+), with any power supply I use. I plug in a wifi dongle, boom I'm connected. raspberry pi 4 wifi in US on 2.4ghz band is fubar. Think I can setup a 5ghz ap, but that is not the issue, I'm getting

server wpa_supplicant[2648]: wlp8s0f3u3: AP-STA-POSSIBLE-PSK-MISMATCH dc:a6:32:20:e3:4a server wpa_supplicant[2648]: wlp8s0f3u3: AP-STA-POSSIBLE-PSK-MISMATCH dc:a6:32:69:18:c4 To me this says pi is not xmitting the passphrase correctly via the onboard wifi.

I managed to fix the issue, the error was in wpa_supplicant.conf.

It should be this for Raspbian Buster:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
network={
    ssid="YOUR_NETWORK_NAME"
    psk="YOUR_PASSWORD"
    key_mgmt=WPA-PSK
}

Instead I had it set to :

network={
    ssid="YOUR_NETWORK_NAME"
    psk="YOUR_PASSWORD"
}
