Comment 8 for bug 1337753

OK, after updating the mac-address in Antti's connection file, I was able to get this to work. I now see the following when I run the nmcli command:

root@ubuntu-phablet:~# nmcli c up uuid aab22b5d-7342-48dc-8920-1b7da31d6829
Error: Timeout 90 sec expired.

...and I get the same NetworkManager log messages in syslog about Ad-Hoc taking too long to associate:
