Hans, Many thanks for the response. It gave me a couple of important clues.
It turns out that the problem isn’t the configuration files. As you say, they are actually created automatically when you connect manually with connmanctl. However, wlan0 still wasn’t connecting at boot time after rebooting. I saw in the logs: “wlan0: link is not ready”. It looks like creating a script/service to connect at boot time with connmanctl is the fix for this. You can read about that here: https://groups.google.com/d/msg/beagleboard/jFJ_cOdh0Zk/JTImXUYWCQAJ The end result of what is described there (and in the wildly/criminally out of date Adafruit github repo) is that two files are created: /opt/wifi-reset/wifi-reset.sh This is what is in that file: ----------------------- sleep 30 connmanctl connect wifi_*_managed_psk ---------------------- and /lib/systemd/system/wifi-reset.service This is what’s in that file: ------------------- [Unit] Description=Wireless Network Reset [Service] Type=oneshot RemainAfterExit=true ExecStart=/bin/bash /opt/wifi-reset/wifi-reset.sh [Install] WantedBy=multi-user.target -------------------------------- If you manually connected to wifi using connmanctl before rebooting, wifi should be connected after reboot now. As mentioned in that article, the ethernet port must be disconnected for wifi to connect at boot time. A couple of notes: * ‘ifup wlan0’ and ‘ipdown wlan0’ do not work for some reason. The new commands are (supposedly) ‘ip link set wlan0 up/down’. * wpasupplicant isn’t used for controlling wifi in the latest images (as of March 2020, at least) Thanks again for the response and help, Hans!

A simple connection example: https://www.ev3dev.org/docs/tutorials/setting-up-wifi-using-the-command-line/ You can also configure it to have a fixed ip and other configurations, eg: # connmanctl config wifi_xxxxx_xxxxx_managed_psk --ipv4 manual 192.168.2.x 255.255.255.0 192.168.2.1 # connmanctl config wifi_xxxxx_xxxxx_managed_psk --nameservers 192.168.2.1 # connmanctl config wifi_xxxxx_xxxxx_managed_psk --ipv6 off Or even set it to connect to a hidden SSID by going directly into the configurations file. /var/lib/connman/ cd /var/lib/connman/ sudo su cd wifi_xxxxx_xxxxx_managed_psk# And add Hidden=true to the settings file using your favorite text editor. Hope that helps. Best Hans.

What are the proper configuration files are and what needs to be in those files? AdaFruit says to change the /etc/network/interfaces file. That doesn't work. https://learn.adafruit.com/setting-up-wifi-with-beaglebone-black There are several references to "supplicant" but that doesn't seem to be current. Or is it? This tutorial is a tease but it doesn't work either. It does mention that wifi won't connect if Ethernet is connected at boot, but I'm not sure if it's for this specific adapter or for BeagleBone Blacks in general. https://docs.google.com/document/d/1-CIGQYdk8ZhU3D3UCNn70jc7C9HdXvEZAsiNW71fGIE/edit#heading=h.ftleo32gu3jr I've seen dozens of pages tell you how to use connmanctl to manually get a connection to work. That works flawlessly. But I have found nothing that tells you how to configure connman so that wifi is connected at boot time. I am using the Debian 9.9 2019-08-03 4GB SD IoT image. Unfortunately, repeated attempts to update the board with the LXQT image failed. Can someone please help?
