Got the internal wifi working. Only downside is the webUI stops working unless you plug Ethernet back in.

Go to Network tab
> Wifi tab
>> Enable Wifi
>>> Scan

Choose your network, put in a password, change firewall-zone from wan to lan, submit then save and apply. It should appear under Network > Interfaces under WWAN. Unplug the Ethernet and enjoy.

Supposedly they are not for sale anymore, but a few are listed here in the forum from their owners, already in hand over
the last couple of days.  Browse back some and you will find them.

Good Luck

Are these still able to be purchased?

I seem to be having a high hardware error rate and a high invalid share submission rate.  7600 hardware errors in 1.5 hours, 93% efficiency rate, however the mining pool still shows over 200GHS from my worker.  Is this normal?  I am used to 1 or 2 hardware errors a day and much higher efficiency when GPU scrypt mining (on the same pool).

Thanks I still can't seem to get the machines hashing.

I was able to get it to accept DHCP and see it over my router. For some reason ether the pool was not configured right or something the CGminer stats stayed blank. I think I blew one of the power supply so off to frys before they close. Any other suggestions so this bad boy can be up and running?

For bitminter, use username_workerID  For example, grumpy619_worker1

Try stratum+tcp://mint.bitminter.com:3333 for the pool address, but if it does not work try mint.bitminter.com:3333 instead.

extra options is 'more options' on the last line in the OpenWrt interface under cgminer configuration

I am using BitMinter and for some reason I am not connecting. In the worker name section should it be my username.worker or is it a , or a _?

it also says this in the CGminer APi log

[Firmware Version] => 20131110
cgminer: 176747f
cgminer-openwrt-packages: 0e12b1b
luci: 346e3e7
Socket connect failed: Connection refused

also where is the extra options of CGMiner? Sorry for all the questions this thing is not as plug and play as they claim.

You should leave it static. Put --avalon-fan 80 (or 20) in the extra options of CGMiner. For some reason some of us got quiet units and others not so.

Thanks for the info. I'm still having one hell of a time getting this thing to mine. I got it up and running and now it sounds like someone is vacuuming near my kitchen. I was looking at what the Antminer set up and on the network setting part: The part that says turn LAN setting to DHCP i did that and connected it to a router it did not respond. Doing that does not change the IP address on it does it?

Thank you for this update on your delivery, glad to hear your runs well out of the box.  I can hardly wait to get my five units.

Ordered one of these 1/7, received today in good shape.
Funny to see on tracking it left Hong Kong at 9pm, arriving in USA 9am the same day.

No damage inside the unit, no loose cables, no broken caps, no bent corners.  I took it apart to inspect it, there were no "fuse" labels silk screened on the ASIC boards, however there ARE 2 fuses in parallel at that location, they are marked P.  A Google search shows that these are most likely 32volt 3amp fuses.  There were some loose/cross-threaded screws holding the ASIC boards on the heatsinks and a loose wifi antenna to adjust and tighten.  I added some cardboard and masking tape around the intake and exhaust fans to direct more air through the heatsinks, also taped the gap between the two heatsinks to make a sealed tunnel.  Along the edge where the heatsinks are screwed to case I applied some thermal paste to try and increase heat dissipation.  The fans start at full screaming loud speed at power up, but quickly quiet down to a normal "gaming computer with lots of fans" level.  Reported temps stay in the mid 30s C.  One of the fan cables connected to the TP-LINK board has had 12v and ground cut off at the connector, leaving the speed sense and PWM wires connected.  The red and black fan power wires are soldered to the power board, presumably the TP-LINK cannot provide enough current to run 2 the large high speed fans.  Both fans still slow to a lower noise level after booting up.

Btmine posted in an earlier post that the unit could run on a single power supply, this is not true.  I tried with a single EVGA 1000watt 80+platinum power supply (12v 83amp single rail), with the 24 pin ATX motherboard connector in ATX_24P and nothing in the second ATX_24P_2 connector.  The unit would power up but only use the 2nd blade, running at ~100GHS.  Connecting a 2nd 750watt power supply to the ATX_24P_2 connector powered up both blades, it is now running at ~220GHS.  If I were to splice up a 24 pin ATX motherboard power connector splitter and connect both connectors to a single power supply it would probably work, perhaps I will try it later.

1400Mhz seems to be the limit for these boards, at first they ran for a couple of hours at 1500Mhz but then became unstable, the unit seemed to be rebooting and spinning the fans up to full speed then back to normal over and over, speeds dropped to less than 150GHS.  1600Mhz was even worse, many of the match_work_count units on the api log page were hashing at very low levels.  Everything was normal after switching back to 1400Mhz (~210-220GHS).

I bought two of these

Should I try my corsair 650w psu's? Or will they burn up?

You will probably have a hard time connecting it to your wireless router via the supplied wireless card inside.  If you do get I bet a lot of people would appreciate a post on how it worked.  If  you really need wireless I would buy a wireless Ethernet adapter.  I have a netgear n600 that I connect my slingbox with.  It runs for months without needing a reboot.  Even the Bitmain Antminer S1's wireless is super iffy.

Thank you I've tried to connect to the miner via wireless router and it is not working for some reason. I will try to use the writeup you suggested and hopefully I will get this thing mining. Thank you.

Try following this setup guide for the antminer S1. The OpenWrt works basically the same. Just do not try to overclock. https://bitcointalksearch.org/topic/setup-troubleshoot-bitmain-antminer-s1-180ghs-miner-344970

The main thing is changing the ip to work with your network and then adding your pool info.

The power supply works.

So I got linked up now does anyone know how to configure this thing?

I ordered 1/7, just got my miner in today! Had the usual loose screws, loose antenna, and one wire pulled from the connector that connects to one of the blades. I have two 650w corsair PSU's. But I noticed a few members said these PSU's will not work. Can anyone confirm this?
