Getting WiFi to (NOT) work on my BeagleBone

Getting WiFi to work on my BeagleBone was another project that seemed straightforward. But that too turned into an exercise in frustration.

At the time of writing, I STILL do not have WiFi working. So I'm documenting the various steps I'm taking as I go along.

(Need to beautify below)
1. Ordered USB WiFi adaptor from AdaFruit
2. Installed driver
3. ifconfig showed it was up
4. Modified connman config files as per AdaFruit tutorial: no connection
5. Disconnected Ethernet and used USB terminal: apparently can't use Ethernet and WiFi together
6. I hate connman: no documentation and no diagostics
7. Downloaded latest connman distribution from http://www.kernel.org/pub/linux/network/connman/
8. 'configure' failed to find 'Xtables' library
9. Need to install iptables-dev (http://lists.connman.net/pipermail/connman/2012-August/010671.html)
10. ./configure works
11. 'make install' works
12. Looks like the default installation directories are different from the default connman in Ansgtrom -- I now have TWO connmand (one in /usr/sbin and one in /usr/local/sbin). I bet the configuration files are different too!
13. Rebooted. New connman is running but USB WiFi adapter is no longer up
14. AAaaarrrggghhh!
15. After several weeks away, I'm trying again. I'm connected to my Bone via the USB terminal.
16. 'lsusb' shows my adapter is working:

Before inserting WiFi adapter:

root@beaglebone:~# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

After inserting WiFi adapter:

root@beaglebone:~# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0bda:8176 Realtek Semiconductor Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

1. 'dmesg' shows the adapter and the driver are loaded:

1. Figured out the new configuration files are to be in /usr/local/var/lib/connman/*.config but still no luck. Using connman 0.79 brings up the WiFi module, but connman 1.10 leaves it down.
