I've got a rather odd issue. I recently installed debian 8 on a Toshiba Kirabook and have some issues with the wifi. When going to the gnome wifi selection it says no networks available so I can't choose to connect to anything.
However I got the wifi to work by adding the following to
... allow-hotplug wlan0 iface wlan0 inet dhcp wpa-ssid <myssid> wpa-psk <mypassword>
I'm unhappy that I can't select different networks via the standard gnome interface. However I'm also unhappy to have my passwords stored in plain text like that.
How could I go about debugging this problem so that I'll be able to select different networks based on availability and most importantly via the gnome setting?
This question here disscussed a similar issue and the solution was to remove the SSID from the interfaces. Apparently the network manager does not manages devices that are covered in /etc/network/interface.
After removing it, all networks showed up correctly.
