Ubuntu 14.04 (kde) does not remember wi-fi password, how to fix?

Question

WiFi

Each time you reconnect, you must enter a password.
However, I have another Wi-Fi router for a SIM card, everything automatically always works with it.

Answer 1

The solution is this.
We go through the wrench (point to the network icon in the lower right corner - in the pop-up window with connections from the top-right) in the Connection Editor.
1. go into editing the connection (double click), and on the tab with security - Wireless Security - enter the password.
2. Check the box "Use this connection for everyone" or "All users may connect to this network" It will ask you to enter your root password if there is one.
Exactly in that order!
