LAN can be used to wirelessly connect 2 or more computers or laptops or any wireless devices and can be used to share data in between them or can be used for networking purposes. It is also useful in case you are playing LAN games like FIFA, Counter Strike, Call of Duty, etc with your friends. To create your own wireless profile for using your wifi adapter in your laptop or computer as a router for other people or wireless devices to connect, you can follow these steps. Please note that this tutorial is for windows 7 version operating system.

1. Open Control Panel.
2. Locate ‘network and sharing center’ and click on it to open.
3. Within ‘change your networking settings’ profile, click on the first setting that is ‘set up a new connection or network’.
4. In the ‘set up a new connection or network’ dialog box, locate for the last option that is ‘set up a wireless ad hoc (computer to computer) network’.
5. Select that option and click ‘next’ twice.
6. Now in the dialog box, you will be prompted for network name, network security type and network key.
7. Enter the name of your network which others can see on their device when searching for the networks to connect.
8. In the security type, you can use any of the available type including ‘no authentication’. But for security it is advisable not to use ‘no authentication’ type of network and use strong passwords in the network key so that only the person knowing the password can connect to your network for file sharing or playing games or for any other personal wifi network.
9. Now you will get a confirmation dialog box that your personal network has been created.

If you have checked the ‘save network’ option, then this profile will remain available always when you switch on your wifi adaptor, until and unless you delete that profile. To delete the profile you can

1. Go to “network and sharing center”.
2. Click on “manage wireless networks” which is available in the left sidebar of windows 7 and then delete your wireless profile from the list.
