How to Use My Laptop As a Wi-Fi Router to Connect My Phone to the Internet?
If you want to use your laptop computer as a Wi-Fi router to give your cell phone the ability to connect to the Internet, you will have to create an Ad-Hoc network. An Ad-Hoc wireless network is a type of connection that lets other devices, like other computers or even cell phones, use the wireless Internet connection that your laptop is currently connected to. Ad-Hoc networks can be created using the Windows operating system.
Click "Control Panel."
Click "Network and Sharing Center."
Click on the option in the Network and Sharing Center window that reads "Set up a new connection or network." From the window that opens select the "Set up a wireless ad hoc (computer-to-computer) network" option. Once you have done this, click "Next."
Name your ad hoc wireless connection by typing a designated name in to the "Name" box. If you want to password protect your ad hoc, type a password into the "Password" box. Click "Create." Your laptop will now act as a Wi-Fi router, allowing your cell phone to access the Internet.
