I am still affected by this bug on a fully updated precise. For me, this is completely unrelated to 3G. When I uncheck "Enable Wireless" in nm-applet, I cannot re-check it, and in "Network Settings" I see airplane mode is on, which cannot be disabled. This workaround helps (from http://askubuntu.com/questions/119195/cannot-disable-airplane-mode): sudo rfkill unblock wifi
