Hi JB7,
I was in the same scenario, except that I use G technology instead of N. When I started to send my files to DNS I did it using wifi connection, but as it is slow I plugged an ethernet cable in my laptop and connected it to my router. This way you will experience a faster speed. Now, as I transfer less files to DNS, I'm using the wifi connection again.
Summarizing, when I wanna transfer a large amount of files, I plug the cable otherwise I use wifi connection.
