BeagleBone WiFi can be manually enabled with "test-connman connect" but autoconnect fails
# Adventures In Wireless BeagleBone Black:
# What prevents my Edimax WiFi USB dongle from autoconnecting to my home WiFi network, "Catalina Island Network"?
# NOTE: If you're here to glean info for your own setup, note that I've installed the
# following two connman auxiliary packages which give the tools and test scripts in
# /usr/lib/connman/test that I use below
# $ opkg install connman-tools connman-tests
#
# Also, I've disabled power save mode for the WiFi so that the BBB can act as a server:
# $ cat > /etc/udev/rules.d/wifi_power_save.rules <<-EOF
# ACTION=="add", SUBSYSTEM=="net", KERNEL=="wlan*" RUN+="/usr/sbin/iw dev %k set power_save off"
# EOF
#
# And last but not least, I created a wifi.config file in /var/lib/connman/wifi.config:
# [global]
# Name = Wifi
# Description = Home WLAN
#
# [service_wifi]
# Type=wifi
# SSID=436174616c696e612049736c616e64204e6574776f726b
# Passphrase=***
# AutoConnect=true
# Favorite=true
# boot up the beagle bone black...
# ...
# ...
# I get a prompt, yay!

Ya same issue. I cant get auto connect to work even if ethernet is disconnected. I do have network over usb.
