i have a router on 192.168.1.1, should i set that as the gateway, or must it be 192.168.2.1 on the antminer? (and/or on the router?)
It sounds similar to setting up an avalon.
My, my, my... i wonder why

you think its an avalon system? wake up.
I think it´s a tweaked Avalon design, YES... to much talks that i´m right but you can ignore if you want..
I´ve made contact with BitMain for buying some chips/units to clarify the whole situation.
