This is a nice thing to do if you are in a hotel and want to redistribute a single WiFi connection to other computers.
The setup works as follows: The WiFi with the SSID Telekom is the one being provided in the hotel. Here we can connect to it without encryption, the interface name is wlan1. We then create a second WiFi network where the router should act as an access point for other clients with the SSID Fireburned and we protect it with WPA2.
