I just changed my OS from windows to ubuntu 16.10 and the problem is since then my wireless doesn't work at all, I can't see any WİFİ conection so I have to plug the ethernet cable to get connection.I don't know where is the problem since it was working well in windows. But I checked the network hardware by this comand lshw -C network and here is the output

Did a net search - rtl8723be and ubuntu? Discovered that there are problems with setting up this Realtek wireless device. Some info was available about configuring this device that will be helpful to you. One caveat here - Follow instructions and enter commands Carefully! There seem to be some modprobe commands. This command works with kernel modules and are not to be used without healthy respect. You will have to connect to the net with either another PC or use the wired ethernet connection to get the information and any downloads that may be required. This search could be done on the Ask Ubuntu page as well.

Just go to additional driver ...put the LAN cable(internet cable) it will automatically search for the driver and just install it by selecting apply ...you will be able to use wireless internet in just few seconds... Go for it
