Yeah they include a gigabit ethernet port which is really useful for full quality 4k, amazing how many cheaper streaming devices only have 10/100 ports which I suppose is adequate if all you do is stream Netflix.

But to me it's just cheaping out to save a dollar or two on the manufacturer's part that with ethernet & protocol overhead could result in problems potentially even for 1080p streams. Whereas gigabit even with overhead and lackluster conditions you're going to get 700-800mbps sustained. People think for 1080p bluray dumps for instance that oh bitrates are only around 40-50mbps average but if you fast forward, if you're seeking around the actual bitrate being consumed jumps to double or more at times and that 100mbps port will choke on that and buffer whereas the gigabit will not flinch. And though I don't use the playback speed option myself much Infuse does allow playing back at 1.5 and 2x speeds which consume around 1.5x and 2x the bitrate respectively.

But it's just nice to not have to deal with wireless hiccups too.
