I updated another S9 but both are network conflic with each other. DHCP give me IP address of 192.168.1.100 for both miner. I tried static IP, both got different IP but somehow conflic again... Both work in stand alone but not at same time. Not my first miner, I did on several Antminer since 2014. So WTF ?? What do I forgot ? I changed IPv4 address and mask but leaved IPv6 blank.
