Greetings,
A wifi bug was brought to our attention a few weeks ago, initially I thought it this was a network manager issue after looking into it further I was able to determine that this was actually caused by the Authorization Manager (Polkit). The polkit service was failing to start, but nm-applet requires certain policies that are provided by the polkit service. After narrowing down the problem to polkit I eventually realized that js-1.8.5-10.fc18http://arm.koji.fedoraproject.org/koji/buildinfo?buildID=81991 was the real issue the v5 version of this package was built incorrectly. The issue has since been resolved and the new js-1.8.5-11.fc18 works like a charm, but just in case any of this information is useful to anyone I am posting some of the errors I received while looking into it.
