Now everything is good. They all came with DHCP disabled. Using their soft EbiteMinerMini found them on 192.168.120.--- network, only when connect laptop via cable to my router. EbiteMinerMini DOESN'T WORK with WIFI connection, ONLY CABLE. Thank you.
As for IP 80.140. I saw that 192.168.80.140 appeared in the network for 1 minute and then lost. So I think that this is some kind of bootloader using for factory settings or flashing firmware or something else.
I am also having difficulties finding one E9+, bought 3 and and 4 S9s all showed up between the range 192.167.0.1-254 with advanced IP scanner apart from one E9+ which I cannot find. Could you please give a link where I can download this EbiteMinerMini software to find the miner?
