            Bug ID: 420170
           Summary: WPA-PSK connection failure shows popup
           Product: plasma-nm
           Version: 5.18.4
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: jgrul...@redhat.com
          Reporter: cyr...@gmail.com
  Target Milestone: ---

SUMMARY
When a network has been added to the list of known networks with a key, a rogue
access point with the same SSID, but a different key will seduce plasma-nm to
invoke a popup and ask the user for a new key.

This *might* make sense, in certain circumstances - for example when the user
just changed the wifi-hotspot key. But in most cases, this is either just a
temporary error while a hotspot restart or a name collision for the SSID.


STEPS TO REPRODUCE
1. Create a network with a WPA(2)-PSK key
2. Connect to it
3. Add a second network with the same SSID but a different WPA(2)-PSK key
4. Turn off the first one


OBSERVED RESULT
A popup will appear and ask for the network key

EXPECTED RESULT
Plasma-nm should instead silently ignore the error, add the hotspot to a
blacklist for a short duration of time (like 60 seconds) and try other hotspots
of this SSID.

If the user opens the panel with the networks a simbol might be added for such
situations with an icon like a triangle with a hint like: "Connection issues,
maybe wrong network key?"

With a click a user might then get a popup: With "If you changed the network
key, enter the new one here: "

And a button for help, which explains why this error popped up and what this
might mean.
