No internet access using USB tethering on Android phone I used to access the internet on my notebook by tethering it to my android mobile phone. However recently this stopped working. Even though the notebook was tethered to the phone there was no internet access. Changing phone settings did not help.
On googling I found that my mobile service provider recently disabled internet access over tethering. This can be fixed by the following the steps described here.


Enable USB debugging on your android phone (Settings > Developer options > Enable USB debugging).
Download adb.exe from here and follow the steps here.
Connect the phone to your computer using USB cable.
Open command window in the folder containing adb.exe.
Type: adb devices -l (this will list your device model).
Type: adb shell (to enter in your mobile's shell).
Type: settings put global tether_dun_required 0.
Reboot your phone and you're done!
