It seems that for whatever reason my Mac was not recognizing the Antminer S1 when they were directly connected by ethernet. After connecting the Antminer directly to the router instead, I was able to log in to my router and discover the Antminer's IP address and then log in from there.
yes because your router has 192.168.1.1 as its address.
so the mac auto finds that .1.
then since the miner has 192.168.1.99 all are on the .1. roadway and communication works. do your self a favor and
down load ip scanner from the apple store the free version or spring for the home version
you can find all your gear and never have conflicts ie two s-3's with matching addresses or one s-3 matches a pc they won't work due to conflict
