This is how I got mine working:-
(Using linux GUI)
I reset the antminer by holding in the button for 10 seconds, it then rebooted (I had a feeling it had been reset)
You will need 2 lots of settings. The first lot is to configure your pc/laptop to connect to the miners factory default settings.
The second lot will be configured into the miner.
Then the first lot will be discarded as when you perform 'internet connection sharing' the settings will change (these will now work with your miners new settings.
The default IP on the miner is: 192.168.1.99 so..
create a new ethernet connection
ipv4 settings
manual
address: 192.168.1.1
netmask: 255.255.255.0
gateway: 192.168.1.99
tick 'require ipv4'
then go back to the connections and click on 'Ethernet connection 1' (default)
You should now have network access to your miner -
http://192.168.1.99 in a browser
Now, configure your miner with DHCP
Save and reboot.
Now, go back to the ethernet connection on laptop/pc, change from 'manual' to 'Shared to other Computers'
You will notice all the IP addresses change (10.42..)
