Create Hotspot in Ubuntu for Android Phones

If you have a single wired Internet connection, you can easily setup an ad-hoc wireless network with Ubuntu and share the Internet connection among multiple devices. However sharing Internet connection with android devices could be a problem since it requires an infrastructure ad-hoc.

Here is how to setup ad-hoc on Ubuntu for sharing Internet connection with android devices.

Step 1:
 Press Alt+Ctrl+T to open terminal. When the terminal opens type following command one by one.

sudo add-apt-repository ppa:nilarimogard/webupd8

sudo apt-get update

sudo apt-get install ap-hotspot

Ap-hotspot is an open-source project that automatically creates an infrastructure (Access Point mode) wireless hotspot in Ubuntu that should work with Android and Windows Phone devices

Step 2:

Once done with installing ap-hotspot we need to configure our wireless connection. Enter the following command for configuration

sudo ap-hotspot configure

It will detect the wired & wireless interfaces and ask you to confirm that if they are correct (run ifconfig if you’re not sure). Then you’ll be asked to enter a wifi hotspot name and setup a password.

Step 3:

Once done with the configuration all we need to do is start the hotspot. Enter following command to start hotspot.

sudo ap-hotspot start

Now your android phone should be able to detect the wifi hotspot.

To stop hotspot enter following command

sudo ap-hotspot stop

Note: If you are getting "Access Point Mode is not supported by this device" error try updating to ubuntu 14.04 ;)
