unexpected burts of wifi password requests
[Moving this over from the gnome bug tracker (here)]
Whilst already connected to my home wifi, I sometimes get a random popup telling me that a password is required to connect, with the password already filled in, forcing me to click okay before it then re-establishes the connection.
Yesterday, after being connected and working for several hours, in the early hours of this morning I suddenly got five requests within the space of a few minutes. The previous night I curiously also got a burst of requests during a short period in the early hours.
The gateway is located a few feet behind me on the other side of a wall, with an open doorway a few feet to one side. I don't see why the signal should be so weak as to cause such flakiness. I'd been working from the same location all day and night, and the prompt issue had not occurred during the several early hours of use.
The Gnome people suggest that it's related to a flaky connection, and NM cannot distinguish the cause of the problem and thus a password prompt is given in case the password is wrong.
I feel that there is surely a bug causing this to happen, otherwise if the connection was so flaky from where I'm sitting, it would surely be happening all the time. Furthermore, considering how much time it's been successfully connected, and how easily it reconnects upon clicking 'okay', surely NM or whatever is not trying hard enough or not being smart enough, resulting in poor UX with these repeated unnecessary prompts.
I'm running Debian sid, with network manager version 1.26.2-1.
I'm attaching some journalctl output. I've stripped out a lot of no-doubt unrelated entries (I was thinking that I'd be pasting it inline when I did so, forgetting about the attachment feature).
