Hi Sarath,

You can easily create a hotspot by following the below steps:

1. Setup a Wi-Fi Hotspot Using Connectify

If you want to setup a Wi-Fi router hotspot with loads of options and a nice interface, Connectify has a great application called Hotspot that lets you easily create a hotspot from your internet connection.
If you pay for the Pro version you can even use your PC as a Wi-Fi repeater or a wired router, or share a tethered connection off your phone.


2. Windows 7 ad hoc nretwork

Open the Manage Wireless Networks window, click the Add button, and click “Create an ad hoc network.”
Enter a name and pass phrase for the network and it’ll appear in the list of wireless networks.
Select it and your laptop will disconnect from its current Wi-Fi network, hosting an ad-hoc network your other devices can connect to.
Be sure to activate the “Allow other network users to connect through this computer’s Internet connection” checkbox if you want to share an Internet connection. For example, a wired Ethernet connection, with the devices connected to your laptop’s hotspot.

3. Setup a Wi-Fi Hotspot Using Virtual Router

To creates a virtual Wi-Fi adapter that allows you to be connected to a Wi-Fi network while hosting your own Wi-Fi network. You can do both things at once with just a single Wi-Fi adapter.

You can download Virtual Router and launch it.

Provide a name for your network, enter a passphrase, and choose the connection you want to share with devices that connect to that Wi-Fi network. Click the “Start Virtual Router” button, and you’re done. You can even see a list of connected devices in this window.





I hope this helps you to create a hotspot.

Lokesh
