It has to be a network problem. I've eliminated everything else.
I'm using an old hub/switch and I'm afraid I'm getting some kind of traffic conflict.
I have a router with two switches, each has 4 devices.
The mining rigs have no IP conflicts and mine fine no matter what I change, but the damn antminers won't get along.
It doesn't seem to matter where I plug in the 2nd T9, both A3s work and one T9 works, but one starts having ping errors on the network diagnostic page, then it stops responding to anything
I had initially tried doing that but immediately ran into problems. I was scared and thought I would never figure out how to get them back up. But then one at a time I used the IP report button to reset, and was able to confirm they all work fine independently but connecting one at a time results in 3 working great, then the 4th will respond to stuff but then drop off entirely until I turn off one or more antminers.
What gets me is if I power off the eth rigs attached to the network, I get the same result, so it's not like a maximum device problem of traffic problem.
They all have different IP's so it's not an IP conflict.
I'm so confused.
