Have you got a computer with a wired internet connection and a wireless LAN card available and you want to connect your wi-fi enabled devices to internet, then here is a solution to create a Wi-Fi Access point using your computer. Hence you can share your single internet connection with multiple devices, as well as have the flexibility of internet access on the go.
It is assumed that you are having the following available with you:
(a) A computer running Ubuntu operating system (we used 14.04 LTS for this setup).
(b) A wired internet connection.
(c) A wireless LAN card.
For the purpose of creating a hotspot or access point we will utilise ap-hotspot software.
First of all install ap-hotspot as follows.
(a) Open a new terminal from dash or use keyboard shortcut “ctrl+alt+t”.
(b) Issue the following commands in sequence:
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install ap-hotspot
(c) After the installation is a success, issue following command to configure the hotspot or access point:
sudo apt-hotspot configure
It will detect your network connections and if all is correctly listed, it will ask you to enter an Access Point name (SSID) and access key (WI-Fi password).
(d) After above step we are ready to start our hotspot or access point. To start the hotspot issue the following command in the terminal:
sudo apt-hotspot start
(e) To stop the hotspot, issue the following command:
sudo apt-hotspot stop
Happy internet connection sharing with your wireless devices.
