On my Fire TV Stick I found the MAC under Settings > System > About
bkman,
What would this address be used for? I thought that fire tvs and sticks had to create MAC addresses beginning with 00:1A:78.
That is incorrect, the last 3 can be random 0-255 in hex. you can use the following link to generate a MAC.
http:// www.hellion.org.uk/cgi-bin/randmac.pl?scope=global&oui=00:1A:78&type=multicast Then link it to your Donation, if it fails, repeat until you find one that links. Then enter that in to the client.
What I said isn't incorrect. He can use his own, or generate a random Mac.
