Android wifi tether is an application which allows root users to convert android mobile into wifi router. This application enables tethering via wifi and bluetooth.
Once you install this application, your laptop or any clients can connect via wifi (ad-hoc) or bluetooth and get access to the internet using the 3G, 2G mobile connection or the wifi connection which is established by the android mobile phone.
One disadvantage is that this application runs only on rooted android handsets.

In case you dont have root permissions, you’ll see a warning message. If you’re already having root per. and not able to start the app, then goto main tether screen, try going to Menu->Setup->Menu->Reinstall binaries/configs.
