Public bug reported:
I'm at a hotel. There's a strong network AP in this room that my org
owns, and a weaker hotel wifi AP elsewhere.
Before my org convened, I connected to the hotel wifi, so it's in the
list of SSIDs that I automatically connect to. I would rather connect
to my org's wifi in almost all cases. But, that doesn't happen, and it
connects to the unwanted hotel Wifi AP. I should be able to order the
SSIDs that I will automatically connect to my dragging them in the list
and a lower network should never be used if a higher is available.
So, in picking a network to connect to, we should try each in order of
user-defined preference and abandon any that are below some threshold of
usefulness.
Additionally, if nothing more-preferred is available, pick among
crypto'd networks, abandoning too weak.
Then pick according to strength if everything else is equal.
I describe best in code...
order_of_preference = sorted(((net.user_defined_order if net.strength >
epsilon else INFINITY), (0 if net.has_crypto else 1), net.strength, net)
for net in network_list)
net_to_use = order_of_preference[0][3]
