WiFi is hit or miss on these and I don't think its actually supported, they just happen to be using a WiFi router as a control unit.

Your best bet is to get a cheap WiFi extender box with an ethernet port and plug into that. I have several hooked up like that and they work fine, but either way you have to make sure you have good WiFi coverage without interference.

is the cgminer file gone or maybe it's just the content of the file?



You can always scp a cgminer   file from another ant to your local drive, edit it and then scp the file back to each miner having the problem to the same location   /etc/config

If you're running Linux on your current machine:

If you need a copy of the originaletc/config/cgminer  file, I think I have a copy.  Were you trying to open up the api port on the Antminer?  It seems to be open by default as I'm able to access my Antminers using Anubis, fwiw.

Official Firmware Update: https://github.com/AntMiner/AntGen1/tree/master/firmware

Over Clocking to 200GH/S (May void warranty) - Plz Scroll Down!


This is how you’ll receive your Bitmain AntMiner S1 180 GH/S miner.






Tools and Parts you will need:



You must power up the miner.  To set up your power source for the AntMiner, the miner will use average 360W at the wall outlet.  So at least 400W computer PSU is needed.  (450W PSU with 80 PLUS is recommended for the stable operation)  For this guide, we selected to use Antec Neo ECO 450W ATX 80 PLUS power supply.


Setting Up the PSU (ATX Computer Power Supply)

IMPORTANT!!! You will need 1 jumper wire.  On the PSU’s 24pin motherboard power cable, you have to cross the “Green” line and the “Black” line. (The PSU has a computer inside and it communicates with the motherboard.  For this setup, there is no computer motherboard to connect to, so, we have to make the PSU think it’s connected to the motherboard and the PCI and PCI-Express ports are needing the +12 V power.




Selecting the +12V lines from the PSU





If you are lucky to have the PCI ATX and PCI Express Extender cables, do all the cuts on the extenders, so you don’t chop the cables on the PSU itself.

WARNING: An 8 pin 12 volt cable has yellow wires on the same side as the connector clip. An 8 Pin PCI Express cable has black wires on the clip side. (See Above Pinout Diagram)

We need at least 2 available +12 V line. (Yellow and Black. 6 black and 6 yellow are recommended)  The miner has 2 hashing PCBs and each needs own power source.  We If you just use 1 +12V to each PCB, it will more than likely over load the line and we DO NOT RECOMMEND it due to the HAZARDOUS CONDITION.  

PCI ATX plug is usually +12 V line.  These are the plug with 4 wires into 1 plug and you’ll see 2 plugs as a pair.  PCI-E (PCI Express) plug can be +12 V line as well.  By cutting the PCI ATX plug, you’ll have total of 4 yellow lines and 4 black lines.  

Cut off the PCI-E (If it’s +12V) connector and you’ll have additional 2 yellow lines and 2 black lines.

Peel off the rubber from the end of each cable.  If you have access to the solder, apply some solder to the tip of the exposed wire.


Connecting the +12V Power Cables from the PSU



Undo the screws on the power connection adapter on the top of the AntMiner.  

Insert each yellow line into the red sticker marked as +12V and insert each black line into the black sticker marked as GRD.


Let's Find Out Your Home Internet Setting



[Windows] While your computer is connected to the Internet, go to the Command Prompt and type "ipconfig" then press "ENTER" Key.  This will give you the network information you'll need later.  Please write it down!


Power On the AntMiner & Connect the AntMiner to your Computer



By using the regular Ethernet network cable, directly connect the AntMiner and your computer.

When you turn on the AntMiner the first time, the fun is off, and you'll see 3 LED lights turn on connected to the Control Board with the Ethernet Port.  A red and green LED turn on under the white-colored cables on top of the AntMiner.  The 3rd light is the green LED for the Ethernet Port.  It's very quiet at this point.


Setup IP address on your computer





If you are using the Microsoft Windows 7, here is the step by step process to configure your AntMiner.

Start Button  >>  Control Panel  >>  Network and Internet (View network status and tasks)  >>  Change adapter setting (Left side of the screen)  >>  Local Area Connection (Double Click)  >> Internet Protocol Version 4 (TCP/IPv4) then Click on “Properties”  >>  Select Use the following IP address:

Please look at near the cooling fan on the AntMiner.  You’ll find a white sticker with an IP address printed on it.  (Example: 192.168.2.125)

Set your computer's IP address to the following:

IP Address: 192.168.2.254
Subnet: 255.255.255.0
Default Gateway: 192.168.2.1

For the DNS Setting:  Select “Obtain DNS server address automatically


Confiigure AntMiner for Mining Bitcoin



Open a web browser and type the IP address printed on the sticker above the cooling fan on the AntMiner. (Example: 192.168.2.102)

A login page will appear on the web page and ask you for the username and the password.  (Default Username: root  Default Password: root)

After log into the control panel, please go to the Status Tab then “Miner Configuration” tab.

Here, please fill out your mining pool information.

Example: Pool 1
Pool1 worker: worker’s name from your mining pool account
Pool1 password: worker’s password from your mining pool account

If you have multiple pools you want to mine, you can add pool 2 and pool3


AntMiner Network Setting (LAN)



By DEFAULT, it should be already set as "DHCP Client" mode, but if it wasn't for some reasons, please change it like the above picture.  Then hit "Switch protocol" button, wait for the screen to refresh, then hit "Save & Apply" at the bottom.  Wait till the update completes.  (Updating may take 1 - 2 minutes.  If it hangs, try again)


Change IP address of the AntMiner [Option]



*** If you decide to change the AntMiner's IP address, Please Write It Down & DO NOT FORGET it.  If you forget the IP address, you will not be able to access AntMiner again. ***

If your home/office network uses the home/office Internet Router (Wi-Fi included) with the common or the default setting, more than likely your network IP setting will be 192.168.1.XXX.  For this example, let's assume your Internet Router (Wi-Fi Router's) setting as follow:

If you don't know the Internet Router's IP setting, and you are using the Microsoft Windows, please go to the command prompt and type "ipconfig".  It will show you the computer's IP address, Current Subnet Mask and Default Gateway. (Please see the above photo)

DHCP: Enabled
Gateway: 192.168.1.1
Computer’s IP: 192.168.1.105
Subnet Mask: 255.255.255.0
DNS: blank ( or 192.168.1.1)

You want your miner's IP address to be 192.168.1.XXX (any number up to 255 that is not taken yet.  192.168.1.254 could be a safe one to use)

Once connected, Go to Network Tab, then select WAN
Protocol: Static Address
IP4: 192.168.1.254
IPv4 netmask: 255.255.255.0
IPv4 Gateway: 192.168.1.1
IPv4 Broadcast: blank
Use custom DNS servers: blank or 8.8.8.8

Then click on Save & Apply.  Please wait for 1-2 minutes to be updated.

Unplug the Ethernet cable from your computer and connect it to the Internet Router ( or Wi-Fi Router's Ethernet Port)

You'll see small green-colored LEDs start flashing on both side of the miner in about 1-2 minutes.


Own Network Setup Just for the AntMiner (Optional)

If you want to keep the AntMiner's default network setting as is, while you mine bitcoin, you can setup another Internet Router.

Example: The AntMiner's Sticker said, "192.168.2.125"

Set up another Internet Router Wi-Fi Router to the following setting:

Default Gateway: 192.168.2.1
Subnet Mask: 255.255.255.0
DHCP: Enabled

Once the new Internet Router is configured for the IP address in the range of 192.168.2.XXX, connect the Ethernet Cable from the AntMiner to the Internet Router!

Wait for 1-2 minutes, and you'll see the green-colored LEDs start flashing on both side of the miner and that indicated the mining operation is in progress!


AntMiner Alternate Wi-Fi Mining



Even though the Bitmain AntMiner supports built-in Wi-Fi mining, to get the best out of the miner while running Wi-Fi at home, here is an easy solution for you and we tested it for over 24-hours and so far it’s working.

You can use any similar items to make it work.  We picked readily available item at the US BestBuy Sotre.  Netgear Model#: WNCE2001-100NAS.  (Price was $49.99)

If you happens to be living in a dorm, apartment or wherever you can only access to the internet via Wi-Fi, this will make the Bitmain Antminer believe it’s connected to the wired Ethernet and this will not stress the miner.  

Bandwidth use during the last 24-hours or more like 36 hours happened to be RX: 38.86 MB (161800 Pkts.) & TX: 14.68 MB (105524 Pkts.)

We purchased the above item to test it out with the Bitmain AntMiner and it worked!



TROUBLE SHOOT

1. It hangs at "Updating Cgminer"



Please go to your control panel, Status >> System Log

If you see the following error or something similar, Your DNS server is not resolving the address or connection to the following servers are restricted/filtered by your ISP or County's Restrictions


Here is the list of IP Addresses to the NTP Servers

198.58.100.237
209.118.204.201
199.195.193.200
189.211.62.210


2. Clicking Noise from the AntMiner

If your AntMiner was making many rapid clicking noise from the PCB, that means you lost the Internet Connection to the AntMiner.

You can shut the AntMiner down while you wait for the Internet Connections to come back or you can just leave the AntMiner as is.  When the internet connection came back, it will start mining on it's own.  (So if you lose the internet connection for whatever the reasons, as soon as the internet connection comes back, it will auto mine BTC without any intervention)

When the miner loses the internet connection, the miner status page seems to reset the time counter (timer) but no negative effect to the mining operation.

There are two (2) ways to tell if your miner lost the internet connection. First, you’ll hear the clicking noise from your miner. (Also the 2 small green led lights on both side of the miner will stop flashing.)  The second way is go to the miner status page and the running timer (Elapsed) will reset and start from “0”.

Here is the video to show what the minder does, when the internet connection was disrupted.  It make constant clicking noise, and the green LED on the PCB (Main PCBs for the ASIC Chips) will turn off and the fan would turn off.  When the miner regain the internet connection, the clicking noise goes away and about 30 seconds or so later, the green LEDs will start flashing again. (These Green LEDs indicate the miner is actually hashing) Then, the fan will starts.  When you go log onto the miner's control panel, the time counter on the miner's status page will be reset.

3. AntMiner Keeps Shutting Down

AntMiner could be powered on for 50 minutes before it shuts itself down.  OR It could be powered on for about 30 seconds then it shuts down. Your problem is more than likely in the PSU.

Please check the jumper cable to make sure the PIN16 (Green) and PIN17(Black) are crossed. (Make sure you are not using the thin loose wire or paperclip for this)

If the Jumper Cable is jammed in and set correctly, it could be your power supply unit.  I understand that you could be using the 550W or even 750W PSU but it may not be strong enough to do the job.  To check the PSU, run your AntMiner in 1 Blade Mode.  

Disconnect all the power cables from the 2nd Blade. (1st Blade is the Network Cable Port Side)  Disconnect the white plug on the top from the 2nd Blade.  Then Power On the AntMiner.  If the problem was in your PSU, AntMiner will power on and it will start mining at about 90GH/S.

If you really want to test out the 2nd Blade, then replace the 1st Blade with the 2nd Blade. (By the network cable port, there are 2 white plugs.  Make sure both are connected to the 2nd blade)  If it power on, then the problem is for sure in your PSU.  Please go get a brand name reliable PSU.

If you have an extra CD/DVD drive laying around, try plugging it into the Molex power cable to create the base load on 5V line.  Depends on your PSU Model, it may fix your looped auto-shutoff.  (http://reprap.org/wiki/PCPowerSupply#Base_Load )


4. My +12V Molex/IDE/SATA Powerline is getting very Hot

If you used the +12V line from the Molex/IDE/SATA Power Cable and the AntMiner powered on, but, the power cables are getting very hot and Miner is under performing, PLEASE DISCONTINUE using the Molex's +12V line.  The 4-pin Molex or so called SATA/IDE power cable has 1 +12V line (Yellow), however, this line's maximum current is usually 5 Amps and 60W.  That is not enough to support each Blade that requires about 180W to run smooth 90GH/S hashing.  Yes, it is the yellow-colored line, but the power specification is different from the PCI or PCI-E Power Cables.

Usually, +12V from the Molex power cable will not let you power up the AntMiner, but there are instances that the miner will power on. (NOT RECOMMENDED!!)


5. My PSU's cables are not color-coded, I don't know what to do!



Please look at the above photo.  It will show you the pinout information.  There are several different shape of connectors and power specifications.  Please pay Special Attention to the 8-Pin Power Connectors.  There are 2 kinds of 8-Pin Connectors.  WARNING: An 8 pin 12 volt cable has yellow wires on the same side as the connector clip. An 8 Pin PCI Express cable has black wires on the clip side. (See Above Pinout Diagram)


6. I see "x" in the ASIC Status

For the ASIC status wise, "x" doesn't necessary means the chip is faulty or failing.  If the hashing power seems to be affected, please check your PSU and wiring and reboot and check the status a few times.  It should go back to an average 168-180 gh/s range per AntMiner.

when you are getting "x" on the ASIC chip status, please turn off the antminer and double check your PSU cables are connected well and restart.  Check the status in about 5 minutes and every 30 minutes for a few hours and see if the "x" are showing up constantly at the same chip or randomly changes or completely disappear.


7. My AntMiner arrived with no IP address sticker

Also, this applies for the lost IP or possible wrong IP on the sticker, using this soft wear will tell you what AntMiner's IP is!  (Thanks to JohnC. for the URL)

Using this IP Scanner would save you a lot of time searching for your Antminer.
http://www.advanced-ip-scanner.com/


8. My Mining Pool Speed is slower than 180GH

Please check your AntMiner's Mining Status Page.  If the status showed 168-180, your miner is working as it should.  The mining pool speed calculation is based on what you transmit to the pool after the hashing.  It is normal to see the mining pool gh/s speed fractuate and sometimes it may show significant lower hashing speed.  Please check your network condition and maintain a stable internet connection. On my miner, I have seen 120GH/s speed at BTCGUILD when my Internet connection was cutting in-out for a a short period of time due to the ISP problems.


9. How do I Upgrade my Firmware?



If your AntMiner's PCB shows 2013/11/4, you can upgrade to the current firmware to reduce high HW Errors and fixes ASIC Chip Status Errors and others.

Login to your control panel, then please go to System >> Backup/Flash Firmware

From there, please use "Flash new firmware image" and click "choose File"  then Click "Flash Image"
