I recently changed the password on my router. Then, when I went to enter the new password for that wifi connection, the right click doesn't work. Without a right click, there is no option to forget that network and so there is no option to enter a new password.
Needless to say, the right click works fine elsewhere. I wound up having to change the router password back to what it was before.
So is this a bug that needs to be fixed or is this another one of those super-counter-intuitive "improvements"?
[Edit 27 March, 2017: Finally, when the network shows up with something like "authentication problem", you can just click on it and it asks for the password. This makes the answer below moot. For more info, see my comment of 17 January.]
