I need your help desperatly in trying to figure out how to connect 1 deco m5 to ethernet for computer and still have wifi. I have a cable modem and the main deco is connected to that, located downstairs. I have a deco in the living room(dowmstairs) and the last one upstairs. My new job requires the upstairs computer to be wired directly into ethernet (no wi-fi connection, like it is now). Can I just take an ethernet cable and plug it from upstairs deco into my upstairs computer or do I have to do something else?I've tried reading different threads and info but it's confusing to me. I need it in layman's terms. Any help would be greatly appreciated. Thanks!!
