How to create wifi hotspot in access-point mode on Ubuntu 14.04

In our office we had only wired internet connection, I wanted wifi connection for internet access to my mobile phone. I have tried WiFi hotspot created using Ubuntu’s pre-installed network manager, but it was not working properly. I have searched a lot to get one good WiFi hotspot solution that is working in Ubuntu 14.04. The solution was to create a WiFi Hotspot in access-point mode. For which we need a network card which supports access-point mode.

This solution works only with, WiFi/Network cards supports access-point(AP) mode.

To check whether your network card supports access-point mode or not, use the following command:

    $ sudo apt-get install iw
    $ iw list

Look for AP entry under supported interface section. If it is present you can proceed.

Ubuntu’s pre-installed Network Manager doesn’t support AP mode, So we are using the KDE’s connection editor which supports the AP mode. You can install it using:

  $ sudo apt-get install plasma-nm

Once it is installed You can start it by

  $ kde-nm-connection-editor	

After opening it, click Add Button and choose Wirless(shared). Now in the Wireless tab set an SSID and choose Access Point mode.

Now set the password in the Wireless Security tab and Click OK.

Now your WiFi Hotspot will be visible to all other devices.
