My father is a retired photographer and converted the garage to his studio. At the moment the home wireless network will not reach the studio. As I have not used a Powerline adapter I was hoping someone could recommend an inexpensive model that would work. I imagine he doesn't need 500Mbps in bandwidth but I could be wrong. Also is there a big difference in price between the models that feature WiFi on the user end compared to an ethernet connection? The listings I see mention "starter" kits I assume this is what he needs. Thank you for your time in advance.
