Used it, worked well for the 1080p 60 streams for stability
Recently found out the adapter is only 10/100. So it's actually slower for me than wifi since I switched to 1gig internet speed(averaging 150mb/sec on Fire stick 4k on wifi.)
9-15.00 Walmart or Amazon sell them
The ethernet adapter cord works perfect
The problem may not be wireless connection are you took far from your router!?
