I'm using Ubuntu 14.04 LTS and my laptop WiFi stopped working after some time. It remains stopped until I reboot my system.

Command:

lspci -knn | grep Net -A2

Output:

08:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723]
Subsystem: Hewlett-Packard Company Device [103c:2231]
Kernel driver in use: rtl8723be

Press Ctrl+Alt+T

On terminal type this command

rfkill unblock all

This will help you if you have soft blocks on your network interface

If it doesn't work try these

ifup This command will bring your network interface up.Run this as your root by specifying your network interface

If you don't know your name of your network interface try this command ifconfig -a
