I have powered up my miner and connected the ethernet-cable to my laptop. But I cant access the Antminer via its IP.
Whats wrong?
Edit; I followed this guide at first, changing the network settings and w/e. But now I se other guides that just connect miner and pc and then just type in the IP in the browser to access the miner.
Now nothing works..

If nothing works, because you don't know the IP anymore, you could push the reset button.
All new versions of the Antminer have that without having to do funny stuff to reset it.
Download Netscan from Softperfect instead of the IP scanner in the tutorial, this one works better and find a lot hidden IP's.
