Making Sure You Have an Internet Connection
The fastest way to make sure you have an Internet connection is the
ping command, which is on pretty much any device you might want to use that’s connected to the Internet.

Look for the
time=69.9 ms portions to look for spikes or lag. Anything over
100 ms should be cause for alarm — go figure out what’s wrong.
If it doesn’t work you will see something like this (misspelled).
