HOW TO USE INTERNET ON PC USING ANDROID PHONE ?

Android wifi

When you're using an Android device with mobile data connection enabled, wouldn't it be convenient for another computer device such as a Windows-based notebook to share this connection for access to the Internet? Yes, you can do a wireless connection via a portable hotspot, or a wired connection using a USB cable:

Turn your Android mobile into a portable Wi-Fi hotspot

On your mobile, go to Settings > More > Tethering & portable
hotspot.
Tap "Portable Wi-Fi hotspot" to enable it.
Tap "Configure Wi-Fi hotspot" to enter an ID and password to prevent unauthorized connections.
On a computer with Wi-Fi connectivity, click the network icon on the system tray to identify and connect to the wireless network you set.

Enable USB tethering on your Android mobile

Connect a computer to your Android device with a USB cable.
On your mobile, go to Settings > More > Tethering & portable hotspot.
Tap "USB tethering" to enable it.
On the computer, click the network icon on the system tray to identify and connect to the wired network. The Windows system may take more than a minute to discover the network for Internet access.
Note: Enabling Bluetooth tethering on your Android mobile to allow for Internet access from a computer is also possible after the two devices are paired.
