Now that fiber connections are more widely available (including in my house) sometimes I will plug my laptop in to a wired connection so that I can take advantage of the higher speeds. For general browsing and listening to music it doesn't make much difference whether I am on wifi or wired in, but when transferring large amounts of data, it can make a big difference. But when I plug in the wired connection, do I need to disconnect my wifi to ensure I am using the connection? How do I tell which connection is being used? The answer is found with the Linux tools route and traceroute.
