Can I use my Android device as Wi-Fi Adapter for my PC (i.e. Tethering to PC through USB, but using Wi-Fi not Phone Network)?
You can achieve this natively on some versions of Android (for me it works on KitKat 4.4.4). All you have to do is connect the phone to wi-fi as usual and then connect the USB cable and do a USB tether. Some devices may require you to enable WiFi sharing in the mobile hotspot settings. Your computer should detect a new hardware - a &quot;USB ethernet&quot; or similar, you may need to install drivers for that, ymmv. Then it behaves just like any other network card. This works for all common operating system, including Windows (where the drivers part may apply).
Just to be sure, you can disable mobile data on the phone for the time being but the phone should be smart enough to route traffic via wifi automatically when it is available.
No root needed.
