Correct. What you are seeing is close to the maximum rate that 100Mb tv connection can deliver. The point I was trying to make is that the TV is not throttling anything. If you have QoS on the router then the router can throttle and if your ISP has a problem with your data, it will also throttle. Internally home networks are subject to all types of congestion and interference and other bandwidth issues. It doesn't change the fact that wireless AC is many times faster than 100Mb connection, unless your router is located on the other side of the house and the neighbors are all using the same channels etc.So far, what I can conclude is that if your KS8500 is Ethernet hard-wired (like mine), the TV will not throttling the connection. Mine is getting the max for my Verizon FIOS plan (75/75mbps). See the attached results for bandwidthplace.com and the Netflix network check.
Wired connection can actually be faster than wireless since 1) it does not have the encryption overhead that a wireless connection does. For a wired network, it's straight data from the router to the TV. When a wireless network is involved, the router has to encrypt the packets first, sends to the TV, which then decrypt the packets before it is usable. 2) Additionally, all wireless devices shares the same Wi-Fi connection. For example, if you have 4 wireless devices connected to your (say 300mbps) Wireless router, it is split between all 4, so on average, you might end up with a 75mbps throughput per device. This is oversimplifying things since you also have to consider whether the other devices are idle or active....etc.
In my case wireless is faster than wired and both experience the same performance issues with certain apps so it's not a speed issue.
