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. RTL8723BE PCIe Wireless Network Adapter
The answer from here is incomplete. Any other ideas?
The output of
rfkill list all is:
0: tpacpi_bluetooth_sw: Bluetooth Soft blocked: yes Hard blocked: yes 1: hci0: Bluetooth Soft blocked: yes Hard blocked: no 2: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes
PS: disclaimer: crossposting
lspciis supposed to show all hardware connected. When
rfkillsays that it is hard blocked, that should mean it has been disabled at the hardware level. When I press Fn + F5 in my Linux system, no dialog appears, but the kernel disables or enables the wireless card. Try pressing Fn + F5 again and checking the output of
rfkill list all.
rfkill unblock wifias root.
sudo rfkill unblock phy0or
sudo rfkill unblock wlan?
