I would like to set-up my laptop's networking to use exclusively LAN (Ethernet) connection when both LAN andWiFi are available? (In my case wired and wireless connections come from the same router.)

I do not want to simply disable WiFi (though it's just a button push) but to have wired connection set as a preference. Is there an easy way to do so?

    This should already be the default behavior – Ramhound Jan 23 '14 at 22:49

How-To Geek has a very nicely written tutorial which allows you to achieve this.

Summary of tutorial:

  1. List routing table plus addresses and port numbers: netstat -rn | more Note the interface list numerical order. The lower the number, the higher the priority
  2. To change priority of an interface, go into Network and Sharing Center and click on Change adapter settings
  3. Right click the network card you would like to change and click on Properties on pop-up menu.
  4. Select Internet Protocol Version 4 item in the list and then click the Properties button
  5. Under General tab, click the Advanced... button.
  6. Under IP Settings tab, uncheck the Automatic metric box and from the list in step one, assign a new priority in the Interface metric field. Something higher than 1, but hopefully not already used by another interface. Although if they're configured Automatic metric they should re-adjust their priority.
