Welcome to the club. The reset method post above does not work. I have 3 S3 miners and tried resetting them at least 25 times and there is no way to do it that I know of. Even bitmain states that if you forget the IP address you can never access the miner again. As far as I can tell the reset button doesn't do anything at all.c
From Bitmain: *** If you decide to change the AntMiner's IP address, Please Write It Down &
DO NOT FORGET
it.
If you forget the IP address, you will not be able to access AntMiner again. ***
Factory default setting for IP address on S3's is 192.168.1.99, so, when you depress (and hold for a good 15-20 seconds), BTW, make sure your doing this while it is running (also, give it 3-4 minutes to fully bootup before pressing factory reset button), it should reset back to default.
