Do a factory reset, make sure you have a computer on the same subnet, and try to access it again.
I did a factory reset on the antminer and the router and still nothing.
The default IP address for the S3 is 192.168.1.99,
what is the IP address of the machine you are trying to access it from?
My guess is it's something different than 192.168.1.XXX and that's why you can't see the S3. You need to have a machine on the same IP scheme as the S3 in order to see it, usually an extra laptop or something you can change the IP address on really easy, then you can change the S3 IP address to match your home network.
