  • Phew. This was a bit over my head but a lifesaver. Thank you! I had to add the down and restart systemctl commands to rc.local to get wlan0 working. Any idea why? I'd previously done things on Buster Lite with github.com/lukicdarkoo/rpi-wifi and it appeared to have the same general problem. pulling the plug would get things to boot in the right order but no soft command seems to init properly.

  • The rc.local statement you mention to get wlan0 working should not be needed. I recommend starting with a fresh install, then updating the OS to the latest version, then applying the network configuration according to the Raspberry documentation: raspberrypi.org/documentation/configuration/wireless/README.md and raspberrypi.org/documentation/configuration/wireless/…. After checking that it works, you can revise the configuration basing on the notes in this topic. Commented Feb 3, 2021 at 8:14
  • Also one thing if i now change my wpa_supplicant.conf i have to call systemctl restart dhcpcd.service instead of wpa_cli -i wlan0 reconfigure. Is there a better solution!? Commented Feb 16, 2021 at 19:56
  • systemctl restart dhcpcd.service is a way to kill wpa_supplicant and restart it, when wpa_supplicant is run as a hook of dhcpcd. wpa_cli -i wlan0 reconfigure asks the currently running wpa_supplicant to read again the configuration file. Both should be viable alternatives. Commented Feb 21, 2021 at 9:47
  • @ircama thanks for your answer. To get wpa_cli i wlan0 ... reconfigure to work as expected i first need to kill the running (started from dhcpcd) wpa_supplicant daemon and restart it. After changing wpa_supplicant.conf and calling wpa_cli -i wlan0 ... reconfigure the changes are applied as expected. Also when i reboot wlan0 is not connecting. I'm not sure what the problem is so i ended up restarting wpa_supplicant after every reboot that worked :/ ... And yes i used -p /var/run/wpa_ssuplicant and sudo -g netdev as specified in wpa_supplicant.conf. Commented Feb 24, 2021 at 13:15
