WiFi.

If your Cox cable modem is right next door, try disabling Wi-Fi in the DVD and run a wired ethernet to it instead. The problem may be that the Samsung box is so close to the Cox box that the Wi-Fi signal is too strong and is distorting, causing the bitrate to drop somewhat, and Amazon's software is detecting the connection speed and rejecting the connection.

Pure speculation on my part but you at least have something to try.

Most cheap routers provided by ISPs simply can’t handle the kind of WIFI traffic that is asked of them.

Your best best is to buy an ASUS RT-N66U Router, plug it into your ISP supplied router via ethernet cable and stream from the WIFI on the ASUS. All routers are not created equal and essentially the only one I recommend to anyone is this ASUS router. The rest will cause issues, lockup, have crappy range, insufficient bandwidth..etc.
