I have this unit literally 10 feet from a modern, high speed router operating at both 2 and 5 GHz and a fiber optic connection to the internet. Wireless at my house screams for every device except for one; this Roku. I constantly get warnings about a slow connection. I'm at wit's end; I've gone into the 'secret' menu and disabled/enabled network ping. I've moved it up, down, around the room. Doesn't matter. Slow connection to the internet; yet every other device I test gets between 80-90 Mbps. So wishing I had purchased one with an Ethernet port. Maybe it would help if this thing had an external antenna connection, I don't know.
