Public bug reported:
I have a wifi network to which sometimes I connected and stored the password.
I am connected to the wired ethernet network.
Expected: shouldn't ever connect to any available wifi while I'm
connected to wired.
Observed: sometimes, randomly, it automatically connects to the wifi
despite the fact I'm already connected to wired. As a result, I am then
connected to both.
Also, it does so at a completely random time: I've been here for hours,
the wifi has been available for hours, I've been connected to the wired
network all the time, nothing special has happened, I haven't restarted
the commputer or logged out and in or anyhthing (I don't know if the
wifi has become unavailable for a very short interval of time and then
available again, it's unlikely and it wouldn't in any way justify the
behavior), yet for some reason, NOW my computer decides to connect to
the wifi (which it shouldn't anyway for any reason).
ADDITIONALLY:
After that, I explicitly manually disconnect from that wifi network.
When I do this, I expect that the setting to automatically reconnect to
this wifi network when available is turned off (otherwise, every time
you disconnect from a network, it would reconnect immediately). I'm
pretty sure this used to work.
But then, the same as described above happened AGAIN: that is, I was
connected to the wired network (had been for hours), and suddenly it
automatically connected to the same wifi network as above (again, been
available forever), which it shouldn't even if it was set to
automatically connect whern available (given it's connected to wired),
but it isn't even more nonsensical given that I had previously manually
disconnected from it so it should not be set to reconnect automatically.
This has started happening recently.
