I RMA'd this unit, and just got it back. I left it plugged in for an hour before trying to login. I have the same issue of unable to login to the UI / miner config and it not showing up on my router device list. When I unplugged all hashboards I can access the settings. When I reconnected the boards after setting my pools, still not able to connect.
Do I have to pay another 200 dollars and 2 weeks downtime? Is there anything I can do here?
