Hi.. I've been trying to get my fire stick faster and nothing.! I have 2nd generation, bought the 4k and returned it cause no difference and harder to hook up a good kodi build. Now I bought the Ethernet stuff and it recognized it but always went back to my Wi-Fi, returned it. Ok, question is, I bought the HDMI extension cable and now it's not behind my tv, does it REALLY work or should I return that too? When I watch movies they lag a lot and have a great internet signal. What would u do? Thnx
