How to fix wireless problem in Lenovo z50 in ubuntu 14.04?

In my  Lenovo Z50 laptop, wireless is not working in Ubuntu 14.04.

My laptop has RealTek RTL8723BE Wireless adapter.

The wireless is not even displayed in the network settings.

Installed Ubuntu 14.04.1 as it has the latest kernel updates for wireless drivers.

The wireless works now, but it has very frequent disconnection.

Then, found the link

http://ubuntuhandbook.org/index.php/2014/08/install-upgrade-linux-kernel-3-16/

which says Linux Kernel 3.16 fixes all the issues.

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16-utopic/linux-headers-3.16.0-031600-generic_3.16.0-031600.201408031935_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16-utopic/linux-headers-3.16.0-031600_3.16.0-031600.201408031935_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16-utopic/linux-image-3.16.0-031600-generic_3.16.0-031600.201408031935_amd64.deb

sudo dpkg -i linux-headers-3.16.0-*.deb linux-image-3.16.0-*.deb

Ran the above commands and upgraded Linux kernel to 3.16 version.

Now, the wireless is working perfectly.

Thanks for the Linux Kernel team and ubuntuhandbook.org team for the great works.
