    I live in a 2-story apartment, with the router downstairs.

    WiFi is weak upstairs but I have an ethernet cable running to my Cinema Display. When I connect my Mac to the display, both WiFi and Ethernet (through the Cinema Display) are connected but I think the Mac using the WiFi as its primary source, making it slow. How do I force it to use the Ethernet connection over WiFi without turning off WiFi?

    A newer version of the document is here: https://support.apple.com/kb/PH21578
    The summary is that it gives information on how to set network service order:

    • Choose Apple menu > System Preferences, then click Network.
    • Click the Action pop-up menu [​IMG], then choose Set Service Order.
    • Drag a service, such as Ethernet, to the top of the list.
    • Click OK, then click Apply to make the new settings active.
