I was frustrated since the hotel I stayed offered no Wifi, but just ethernet. I thought well why worry? since I have my Nvidia Shield!
So I connected the ethernet to shield but... wifi hotspot/tethering option was hidden! FML! But alas desperation is the mother of invention.
- Installed Sideload Launcher from play store
- Install PdaNet+ from their website with assistance from ES File Manager
And it is on! Wireless goodness!
Nice , did it interfere with the controller at all?
