I am surprised to hear that an Ethernet Adapter wont work;
i was sure it would function the same way as on Android Sticks etc..you just add an Ethernet Adapter and are good to go.
(its true that on many Phones this does not function, but often on Tablets and Certainly Computers).
Are you sure that there is no Ethernet Capabilities on Ethernet Devices?
I mean "micro-usb to Ethernet Adapter", that should normally function.
Also the 3710RW model has a composite Cable included, so i was hoping to be able to use it also for Amazon Prime on an older TV model (albeit probably only in SD quality).
I am 99% sure that no Ethernet USB adapter will work on any Roku player. It is known that they will work on some models of Roku TVs (TCL I believe is one brand that supports them), but they have different internal hardware. For such an adapter to work would require supporting hardware within the player. No one has ever mentioned this working on any Roku player, and I'm certain someone would have said so if they had made it work.

As was stated, that link is four years old. The Secret Menu is split into separate menus now. They don’t offer the functions anymore. Roku has updated the menu over time.
I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan
