I hooked it up to my Chromecast with Google TV and it just worked. It has a blue, not very bright, power indicator at the top, next to the logo, and link speed and activity indicators next to the Ethernet port. Although I didn't hit my max internet speed (300Mbps), I got around 150 on both tests using "Internet Speed Test - Fiber Optic Test". Latency and jitter were also about what I would expect from Ethernet. If I encounter any problems with the adapter I will update this post. Update: I've had this key for 3 months now and it's still working perfectly.
