It's just a nightmare to have 3 antminners that I've waiting profusely for come and i spent over two nights now trying to set this up, ninjatech hopped on teamviewer and took remote control and still could not figure it out, my setup is fucked and i just stare at these boxes.... it sucks for me.
If you can get on the internet you should be able to mine with these things unless the pools port that your trying to connect to is blocked. Have you checked to see that you can ping the pools address from a computer? I dont know how to do that but I'm assuming its as simple as "ping xxxxxxxxx:3300" or whatever it is.
