I'm trying to connect my Android device (Galaxy Nexus with Android 4.3) to Internet via my 3g network that I use on my Ubuntu 12.04

I followed this post on Ubuntu forums.

Installation and configuration were straightforward and I'm getting Wifi signal on my Galaxy like that should be. But one problem appears.

First it get connected, but then it displays a message 'authentication problem' then try to connect again, connect and disconnect with the message above. I used an Iphone to check if the problem come from my Galaxy, but the same message appears 'connection failed, authentication problem'

I also tried hostapd method, like this explained here, but I have the same problem.

Does any one have a clue to solve this issue ?

Thanks for your time.

@avinash-raj : Still have the same problem. The issue is with the authentication message. It stills connecting/disconnecting. I didn't change the default parameters (access point name and wpa passphrase), so I am sure entering the actual pass. –  Zeine77 Mar 8 '14 at 9:37
check that you selected the correct interface and also the passpharse.Or try to reconnect it. –  Avinash Raj Mar 8 '14 at 9:38
my ifconfig after running the script. !ifconfig. Thanks for your interest. –  Zeine77 Mar 8 '14 at 9:47
you have to give eth3 interface while creating hotspot using ap-hotspot. –  Avinash Raj Mar 8 '14 at 9:51
