When you're nowhere near a Wi-Fi hotspot, tethering to your smartphone's data connection is a great solution. Doing it quickly and easily makes it even nicer. Apple has had what it calls Instant Hotspot since 2014, while Google added Instant Tethering to its Nexus and Pixel devices this past January. Now it looks like the quick connection technology is coming to Chromebooks as well, though there are a few caveats.

Enables Instant Tethering. Instant Tethering allows your nearby Google phone to share its Internet connection with this device. #enable-tether"
If you're running this early-adopter build of Chrome OS, you can enable this feature by typing chrome://flags into your URL bar, reports 9to5Google. You can enable the tether option there, restart the machine and then find Instant Tethering in the quick settings menu in the "network" section. The feature will also need to be toggled on your smartphone, which will also need to be a Pixel or Nexus device. With those caveats in place, however, you should be able to quickly tether up your Chromebook and easily get online without Wi-Fi.
