I have a Lenovo B5400 with Ubuntu 14.04 x64. The Ethernet port works fine. How can I enable/disable the WiFi connection? I have no hardware button for this functionality. Under Windows I can press Fn+F5 and a dialog window appears, but I cannot find this functionality under Linux. lspci | grep Network produces:04:00.0 Network controller: Realtek Semiconductor Co., Ltd.
