Stevens ,

It's configuration related - there's a great post here https://bitcointalk.org/index.php?topic=2638479 that gives instructions on software from EBANG.

Basically , DHCP isn't switched on as default on the mines. As a result, a random IP , Gateway and Subnet are default, that don't tie in to typical home networks.

Run the software as described in the above post, and switch on DHCP and it all works as it should.

Happy Mining.
