Hi @GenXI, I just took a look and I can confirm the GUI tool does not seem to be working correctly.
If you right-click on the nm-tray icon, there is a context menu with an option that says "Edit connections...".
Unfortunately, when I click on it nothing happens--seems like there is a fly in the ointment somewhere.
For now, you'll have to remove the network manually.
To list available connections:
nmcli connection show
NAME UUID TYPE DEVICE
Wired connection 1 c449b82f-42a8-3b06-b561-3642b00279ab ethernet eno1
Chance The Router 420188ed-93ca-442c-9678-e8f5546811db wifi --
In my example here, you can see I have the ethernet connection, and also a WiFi connection named "Chance The Router" which I have connected to with the incorrect password.
To remove the Chance The Router connection:
nmcli connection delete "Chance The Router"
It should give you a confirmation like this:
Connection 'Chance The Router' (420188ed-93ca-442c-9678-e8f5546811db) successfully deleted.
Now when I go back to the nm-tray it lets me attempt the password again:
I hope that helps!
