I am having the same issue. I tried to change my ip to static and lost everything in that screen and now it won't change back and i can't connect to the antminer. It isn't showing as being online in my router. I've tried using ip reporter and nothing shows up when i push the button on the antminer.
I've unplugged the miner many times to try and reset the ip address but nothing works.
Any help would be greatly appreciated.
if you haven't already checked out how to reset the antminer :
https://enforum.bitmain.com/bbs/topics/3957it looks like the networking on the miner is out of whack and you may need to factory reset it. I guess since you can't log into it your only option would be to use the reset button.
you can try resetting your router, or even using a different port/cable.
