Tethering is the process of using your Android device, or any mobile device, as a modem. By connecting your PC to your Android, you can now harness that 3G or 4G connection in order to surf the Internet, or anything else the connection allows, from your desktop or laptop.
Note #1: Android users also use tethering to describe the process in reverse, which is giving Internet access to your Android device via a PC. However, this involves “rooting” the phone (gaining super-user privileges), which has some dangers associated with it, and is beyond the scope of this how-to.
Note #2: This how-to describes the process of connecting a single device to your Android in order to access the network. In order to tether multiple devices you often have to purchase an advanced connection plan. Alternatively, you can circumvent the need by rooting the Android device.
Warning #1: Some carriers do not permit tethering, so by doing so you could be breaking your service contract. However, carriers will not be aware that you are tethering, but they will take notice if you begin to download an abundant amount of data.
Supporting USB and Bluetooth, PdaNet gives you full Internet access through your Android device, and it keeps your device charged at the same time, which is an issue with tethering. There is a PdaNet trial period, at which point the free version blocks access to secure websites. If this is an issue, the full version costs ~$24. There are free alternatives, but those that are as functional as PdaNet involve rooting the phone.
Ensure that you download and install the appropriate version for your edition of Windows.
Press Menu, then Settings, then Applications, and then Development. Check the box labeled USB Debugging, and then press OK when the confirmation dialog appears. This allows PdaNet to stream directly between the Android device and the PC. However, it is important to disable USB Debugging when you are no longer tethering since it slows down the device unnecessarily.
Connect your Android phone to the computer via a USB cable or Bluetooth.
Activate the app, and select the Enable USB Tether option, which is on the program’s main screen. Alternatively, there is a Bluetooth option to enable for those using that method.
