How To Share A Wired Internet Connection In Windows 7
How To Turn Your Windows 7 PC Into A Wi-Fi Hotspot
An ad-hoc network is really just a simple and a direct network connection between devices. In this case, you will be creating an ad-hoc network between your PC’s wireless connection and any wireless devices you want to connect. You just need to make sure that your wired connection is set up and that the PC does have Wi-Fi available.
Note that when you set up an ad-hoc network using your PC’s Wi-Fi, it will disable any existing connection that uses that Wi-Fi adapter. That is why this method only works if your internet is coming from an Ethernet source.
Enter a name and passphrase for the network. This will appear in the list of wireless networks. Select it and your laptop will disconnect from its current Wi-Fi network and start hosting an ad-hoc network your other devices can connect to.
Be sure to enable the ‘Allow other network users to connect through this computer’s Internet connection’ checkbox. Your PC will then be able to share its wired Internet connection with the devices connected to the PC over the ad-hoc network.
