I have an Antminer S9 that had a chain that stopped working. The web UI was only showing 2 chains working. I restarted it a couple of times with no success. I went to https://shop.bitmain.com/support.htm?pi ... tDBXAH065D and downloaded a firmware update to try and even tried the Antminer Fix .tar file first. My web UI went not showing any data of any sort in it. I tried the reset of the Antminer, but that isn't doing anything. Now I can't find it on the network. It runs, but it doesn't seem to be hooked into the network at all and I have it hardwired to the router.
Any help please? Is there anywhere that I can get replacement cards if one of the cards is bad? Is there anyone in the US that does repair of Antminers?
