This has eliminated my buffering problems.

I rarely write reviews, but this adapter immediately fixed my buffering problem!

Its a great addition to your Firestick to help fix your buffering problems.

Simply plugged the Cat5 plug into this adapter, plugged the output of the adapter into the power input of the FireStick and then plugged the power supply of the FireStick into the power input of the adapter (located beside the Cat5 input); no more buffering problem plus much faster loading of programs.
