I am using ubuntu 13.04 and till couple of days back I was able to connect to internet using the hotspot connection I had created previously when I started using ubuntu 10...

But two days back I noticed that devices are getting connected to wifi but are not able to access internet..

I deleted my old wifi hotspot and created a new one by going to network settings and there by clicking create a hotspot option.. I logged in from my wife's laptop which is running on windows 7. It was able to establish connection but was not able to access the internet.. Same is happening with my iPhone too I am able to connect to hotspot but for some reason it is not able to access internet...

Any help would be highly appreciated..

Thanks Jacob
