That is strange... do you get the socket refused & can still ping at the same time?  I had the same problem and I had to delete a symlink in the /etc directory that was somehow messing things up.  Could it be a problem with the controller?  I heard TP-Links can have crash problems like that and u have to reboot them.

the unit is in server room. Temp less than 30C. I checked the cgminer log, when it stop hashing it says socket connect failed: Connection refused. If I on/off again the miner, it will hash. If I'm lucky it can hash about 2-3 days non stop. later on it stop hashing. and the log says socket connect failed: Connection refused

Diagnostic ping/traceroute are all ok. no packet loss

I have upgrade the firmware to the latest one. this is Avalon 2 55nm

I mean is it possible that you PSU could be failing, Have you been monitoring the temps, it could be also that the unit is shutting the hashing units down due to over heating

updated to the latest firmware. but still after 2-3 days it stop hashing. I need to on/off the supply to get it start hashing again. soft reboot just not work. any possibilities on the power supply issues? the unit comes with cooler master ex2 625w for 2 units

I can help you no problem Please msg me when your online and ready

LOL well... after all that work, I managed to figure out the net config problems and get the OpenWRT to work just as it is intended!  The bad news?  I just realized that this is a batch 1 Avalon not a 2!!!  So the avalon 2 firmware seems to be useless to me!  It ends up that I have an Avalon 1, and I can get it mining with the Debian Wheezy SD card it came with, but only by SSH... and I would love to have a web interface.  Is this possible?  Because all the firmwares I see on the site are for the TP-Link controller which I do not have, and have heard it has crash issues.

How difficult is it to get the Avalon 1 working with a nice web ui and overclock options on a raspberry pi controller?  Possible?

--edit--

Also I would like newest firmware because I don't think the person I bought this older miner from ever updated it... and that is another reason I want to flash a new system to the SD.

Specs:

Avalon 1
4 Module (20-25GH per) = 100GH average

I can help you i am still here
I sent you a msg on bitmessage also

Ugh, just when I think I finally got it... the dang OpenWRT will not connect to the outside internet...  cant ping, cant tracert, cant lookup nameserver... can't mine

ok thanks I will message you.

--edit--

Thanks for the offer, but I must have missed you.  I think I finally got what I was doing wrong!  I was treating openwrt as any normal flavor of linux, but it is far from it... its more like it just turns  your pi into a fancied router that can mine bitcoin.  Just incase someone stumbles over this thread I will put the instructions I wish I had.

--If your Avalon is not running OpenWRT and you want the latest firmware/cgminer--

How to get OpenWRT mining on your Raspberry pi (or at least what I did and seemed to work):

Download one of the images of openwrt from firmware page (I used the sd-ext4)
Download the raspberry pi root folder archive
Flash the openwrt image to your card
Plug it into your computer with an ethernet cord and enable that connection (disable others) & log in using Putty > telnet connection: 192.168.1.1
type passwd and set the root password
exit putty
take the sd card back out of the pi
boot a linux distro on your PC with the SD card connected to the PC
download / move the raspberrypi root filesystem archive to linux
open a terminal as superuser and or sudo nautilus
overwrite the old sd card filesystem / replace files with the one from the archive
navigate to the /etc/conf folder and set the network settings to what you would set a normal static IP client on your network as (not as a router)
you can now log into the web configuration by typing the IP you just set in the network conf files


After that it is pretty self explanatory... miner settings are right there in the web config as well as many other things.

Thanks to everyone on these boards or I never would have figured it out

I can help you via Teamviewer if you want

I don't know whats wrong with what I am doing... after hours of searching and trial and error I just can't get a bootable firmware on my raspberry pi!  There are many img files in the firmware section and a "rootfs" file... I just cant seem to get openwrt to do anything!  Can you boot and log into it with SSH like any other distro or am I missing something?  There are no clear instructions on flashing a rpi from windows with current firmware and set up my avalon 4 module 100gh.

Any help would be so appreciated and first guy to give me the correct method gets .02 btc!  I am desperate.

It could be a Firmware issue but it is Hard to Say

my avalon once in a while stop hashing as well (2-3 days or sometimes once in 5 days). FW version 3.10.12. reboot cannot make it work, the only way to start hashing by disconnecting the power supply and switch it on again. is it FW issues?

Sounds like the PSU is on it's last legs

Hi all,

I have a Avalon 2nd gen 220ghs device that had been working without any issues for a month. Couple of days back I noticed that the hashing had gone down to 0 and "orange" light was on where it used to be "red" light. I noticed that the PSU fan was not running so i just restarted the device and it started to hash again.

In the last couple of days this thing of "red" light turning "orange" and the PSU fans not running has increased. I have attached pics of how it looks. I was worried that it might become worse so i have it shutdown now. I am not sure if this the avalon controller board prob or PSU and it would be great if someone could help troubleshoot.

U welcome then!

Fans were working properly, after PS swap the boards started hashing again.

Just depends on which model avalon miner you are using

How much montly/day 7/24 used anybody answer ?

How much life have this asic miners ?

thanks.
