I can't see anything abnormal in that log - can you post the other stats with the error count and so on - should be on other pages at 192.168.0.1 (don't even need to login).
As I mentioned before - can you try with different instances of the iPlayer and Prime, Netflix apps ? On a PC, smart TV etc. rather than the TV360

I know a bit about Wi-Fi, Telecoms, and TV as I used to do it for a living but I'm not perfect so don't beat me up... If you make things you make mistakes!
