Comment 11 for bug 438111

Asac believes the present icon is sufficient for ad-hoc device.
This bug is solved in Humanity.

Since the icon is for a device , we cannot add further warnings to the ad-hoc icon since the icon might be used elsewhere in the app too.

It would be more ideal , if nm displayed another icon for such risky devices , symbolizing security alert. At which point a new icon can be made. But for now this issue is solved in humanity
