There are times when you are working on a laptop or a tablet and the internet connection crushes. Or you are in town and you want some internet to some tasks but you can't find any Wi-Fi. No worry. Using your smartphone, you can make it a Wi-Fi hotspot for other devices. This will share your internet to other laptops or tablets.
As we are living in a mobile world, where you don't leave your house without a smartphone with an internet connection, it's well to known that you have 24/24 Wi-Fi connection possibility in your pocket.
To tell you how you can make a Wi-Fi connection, I am using a Samsung Trend Lite device with a Android 4.1.2.
You enter the Settings menu and the select More option. There you can find the Tethering and Portable Hotspot. The USB Tethering allows you to share an internet connection and in the same time to charge the device. Firstly it will be greyed out, but if you connect a laptop via a USB it will lighten up.
Bluetooth Tethering is the same thing as USB Tethering, but instead you use a Bluetooth connection. This two connections also allows you to transfer files.
There is another option "Set up with Wi-Fi Hotspot" which makes a Wi-Fi hotspot. The default values is always AndroidAP and there you can find the password to access the connection. You can change the name of the connection or the password if you want. After you do this, just refresh your Wi-Fi connections on your laptop or other devices and then connect, put the password in and ther you have it !
