Hi, I am trying to connect my Denon AV receiver to my home internet network. The receiver has a wired ethernet port, but no wireless. My modem and router are upstairs, and the receiver is downstairs in a room that I have just retrofitted to be a home theater. I'm trying to decide what the best option would be. I'm looking at buying a simple wireless adapter versus a Wi-Fi extender with an ethernet port versus a powerline adapter. The wireless signal in my basement is not as strong as it is upstairs, however seems to do an ok job with streaming Netflix and things of that sort through a Roku stick that I have plugged into the back of the receiver, and up to this point the signal has not been a source of real frustration. I have not tried streaming any 3-D content. Any advice would be greatly appreciated.
