I use the original Raspberry WiFi dongle on a Raspberry Pi 2. I changed interface file in etc/network and the wpa_supplicant.conf file, addding the SSID and the psk password for my wifi connection. And yet, I am not able to connect to my wifi network. What is even stranger is that in the GUI it seems that the Rasberry doesn't recognise the wifi dongle. When I left-click on the network icon, it says No wireless interfaces found.
Do you have any suggestions that may help me solve this issue?
Here are the last lines of the dmesg command
