My apologies if this questions has been asked and answered (I swear, I searched for it and couldn't find an answer here). We just got a new Fire TV Stick HD after our dog chewed up the remote on our previous one, for which we had an adapter that let us attach to the power source and to our writer so we had a direct wired connection. With the new hardware not needing a power supply and the adapter not fitting the port, is there a way to still wire the connection to the router? Is it just getting a new dual adapter that fits USB-A and has an ethernet port?
