I did tried this from that page: 3. How to set the correct AntMiner DHCP Network Settings:
By DEFAULT, it should be already set as "DHCP Client" mode, but if it wasn't for some reasons, please change it like the below picture. Then hit "Switch protocol" button, wait for the screen to refresh, then hit "Save & Apply" at the bottom.
I tried that now its frozen. Can anyone please help?
You probably changed the WAN to "DHCP Client", so now the Ant is trying - in vain - to obtain an IP Address from your laptop!
It is the LAN that should be left alone on "DHCP client"
Make the changes to WAN.
Yeah... I know it sounds confusing and reversed, but that's what it is.
Good Luck.
