So, I've been running the updated daily build of 14.04 for several months, no problem. With the last, presumably "official" update, I've lost my wireless connection. I get an "empty triangle." When I right click on it, I don't see the toggles for wireless and overall networking, and when I left click, instead of seeing networks I get "connection Properties: eth0, status: error." Presumably this means my ethernet isn't connected, but it works fine when I connect that up.
There's also a "lo, status: idle drop down, and I get the older wireless icon in the tray, but clicking on that leads nowhere useful.
Sooo, I downloaded the official version, which does exactly the same thing. Is this a bug in the official version, or am I missing something simple?
