Status changed to 'Confirmed' because the bug affects multiple users.

I think I see the same thing. I think when I disable wifi and reboot it turns back on, but if wifi has been on, it doesn't bother to connect. And of course this is inconsistent, and sometimes difficult to reproduce. Flight mode on/off doesn't seem to solve the problem

stop/start network-manager allows me to reconnect. I use an MX4 by the way, but now that I think about it I think I experienced the same with E4.5

This happened to me, and was a flaw on the device itself unable to rearm the connection. It also happened in MacOS X.
