Wow, BITMAIN bringing the support team. NICE!!!

I have had this problem before. The things that I did were as such!!

1. Make sure the antminer is set to dynamic (DHCP) and not static. It just makes thing much much easier.

2. Find that IP address. To do this login to your router. 192.168.1.1 or 10.0.0.1 (Xfinity). Once you're in go to "connected devices" (It should say something like this). Once there find the antminer on the chart.

3. Go to that IP!!

4. If it hashes GREAT but one more thing.

5. Make sure you have a password in the password box under Miner Configuration. Also, you may want to try a different pool. I suggest Slush. Some of my miners would not work with ANTPOOL but they all work on SLUSH!!

Hope this Helps
