I have created wifi hotspot on my Ubuntu 14.04 following these instructions. It was working fine. But recently I applied the updates on Ubuntu and since then the hotspot is not working properly. My android device connects to it but cannot visit any website on the internet. I have tried with other android devices, but they did not work either. I can access internet on my laptop (HP probook g3 440) where I have created the hot-spot. I have removed the hot-spot and created it once again just to make sure the settings were not wrong. I also tried creating "access point" type hot-spot ( which I was already using ) with KDE Connection Manager. That did not work either.
[Edit]
Here is a link to the output of wireless-info script: wireless-info.txt
PS: This is where I found the script.
