Always use wired Ethernet when there is the option to do so. Wired is faster, more secure and more consistent. > What are there any benefits of wireless vs wired ethernet? Wireless has all the headahces of a normal Ethernet cable connection but has added overhead of communciating over Wireless instead of a nice clean cabled connection. When USB isnt an option then the next best is Ethernet cable followed by Wireless. No network overhead to worry about, nice and simple hardware connection. The best connection for printers is always USB. I have just purchased a M281fdw and am wondering what the best connection would be?
