I currently have 3 D3 miners in my home. They were all mining consistently for a month and then with no warning stopped working. They were connected to ethernet through the use of a TP-LINK which I thought was the problem. I updated the firmware and the software on miners and the TP-LINK. That didn't work. Then I decided to stop using the TP-LINK and just use a dummy switch. I plugged in the the miners to the dummy switch and only one of them connected. I can no longer get 2 of the miners to connect to the network and change any settings. I have yet to hard reset the miners to factory defaults. Is this the best route? I am just confused at this point. Any help? Thanks in advance!
