Why is there no option for USB INTERNET in WIRELESS & NETWORK SETTINGS on my Nexus 5? I own a Nexus 5 with Android KitKat 4.4.2. I have been trying to do reverse tethering without root as is supposedly possible from Settings → Wireless &amp; Networks → More → USB Internet. But I can't see any USB Internet option in Wireless &amp; Networks. Why not ?? 

Can someone assist me with this ? I am having a PC with Windows XP.
In Android 4.4.x you should be able to find the USB Internet option under:

Settings --&gt; More... --&gt; Tethering &amp; Portable Hotsport --&gt; USB Tethering
