I bought a Dell Inspiron 14 3442 laptop pre-installed with Ubuntu 12.04 LTS , however I am having issues with the WiFi connection. I receive the error message: Has closed the connection every time that I attempt to activate the network. Wired and bluetooth connections are working perfectly but issue is solely with wireless.
My wireless network card is a Qualcomm Atheros QCA95665 / AR9565.
$ lspci -nnk | grep -iA2 net
