To figure this out I'd have to loan out a Roku or similar device.
BUT THERE ARE OTHER CAUSES that drive folk crazy. One of this has folk telling me I'm nuts. Here we go.
1. Be sure the date/time is set to your area in the player and router.
2. Check with the Samsung site to see if new firmware came out. Have Samsung tell you how to check and update.
3. If the above don't pan out, ask Samsung how to factory reset and only load the Netflix app. Check the item 1 again.
I ended up buying a Ethernet-over-power adapter a little while ago (TL-PA411), and up until now it was working a treat, I was streaming full length movies on Netflix in my lounge room with no interruptions/internet disconnections which I was getting before back when I was relying on the Wi-Fi (the reason I stopped using Wi-Fi was because of these disconnections when I would watch movies on Netflix).
I thought the problem with the use of the 'Wired' POE Adapters was solved, but last night the problem re-occurred and I was getting a disconnection 3 times through out the duration of movie despite me using the POE Adapter.
I checked the Blu-Ray Network settings and it was set to 'Wired' so it wasn't like I was accidentally using the Wireless/Wi-Fi setting, yet I am experiencing these exact same internet disconnections with movies on Netflix that I was before.
I repeat, I have had this Adapter for a few months now, and it was initially working, but now the same problem I was having before with the Wi-Fi using Netflix is the same problem I am having now with the POE Adaptor with Netflix.
it got me thinking, could the issue be the actual Blu-Ray player itself? in that the networking/online capabilities of my Samsung BD-H6500 Blu-Ray player is not very good? Because I never have any other issues with my internet speeds or stability when using my Desktop PC, or my XBox 360 for online functionary, or even when I and others in my household are using Wi-Fi for internet access on phones, iPads, laptops etc.
Granted I use the POE Adapters using Power Boards since I do not have available sockets on the walls, but even still the signal loss should should not be this significant.
Does anyone have any other helpful bits of advice for me? Help would be greatly appreciated.
