I bought 2 antminers from Bitmain during Chinese New Year, and they arrived a few days ago.  One of them's a little sketchy though...
It has thermal paste on almost every screw and around the edges of the board.  A little different from the others I have received.  I could post pictures if you want to see what I'm talking about.

The main problem with this board is that I cannot get it mining; whether that is a network problem or a blade problem I do not know.

I've set up several ants before and I am an advid linuxr, so I assume it's the board's problem and not me.

I scanned for a network in the wifi tab, and it found mine with about a 40% connection, which, I assume, is decent.  It's adjacent to my other ants and they work, so I assume it's not a distance issue.  It creates the new network successfully; however, it says it has a 0% connection with no data up or down.  My other miners connect and start running as soon as I complete this step.

My mining pool is configured, my LAN is DHCP, my WAN is static with 8.8.8.8 for DNS, I can log in to the WebUI with no issues.  It's configuration is essentially the same as my other miners; however, this one is not working.

Any suggestions on how I can start her up?

I've already contacted Bitmain, and I am waiting their response on exchanging this one for a new one.  In the meanwhile, I would like it to mine somehow through my computer's connection through Ethernet.  I don't want it sitting here like a paperweight until I get a replacement.

I'll tip anyone $20 or more who gives me some working advice.

Kind regards,

EDIT: Some additional info:
Every time I turn it off, it forgets my network and my time synchronization, even if I hit save and apply; however, it remembers my mining configuration.
Also, the C31 light emitting diode blinks consistently with a frequency of a little under 1 Hz.
No LEDs are lit on the blades.

1) It has more then enough power? (>500W)
2) did you remove the 'ipv4broadcast' configuration? It usually ships with 192.168.1.255 and this causes issues frequently. leave this blank.
3) double-check your gateway IP is correct for your router.
4) forgetting the time sync is possibly just a result of it not connecting to the internet

5) Is there thermal grease that got onto the chips/resisters on the board? You can clean this easily with 99% rubbing alcohol (any drug store) and q-tips. If any goo got into the circuits it could throw errors back from the affected components
6) you can also take a multimeter and check voltages. you should be able to get 1.1V across every inductor

hope it helps find the issue! 1AqY1gMXt5wx6jjvCyveHo1yxj3QrgLiWw
