So it could be some kind of a bug.
Maybe miners have reset their own ip address ?
Maybe Wireshark software can be tried to see if there is any traffic in the local area network, that looks like the miner.

mine behaved like this when I first got them but I do no remember what I did to get them working but I did get them working and they worked flawlessly after that.
I remember I had to play with them and the network quite a bit.

Does the firmware upgrade give any help?

Hi.
Unfortunately i have a lot of this BW-L21 miners. Has anyone had a problem when reset button does nothing. I have at least 50 of them that wont reset and you cant do anything because it wont even show on LAN.

I have the exact same problem right now!
I only have one at the moment, but had to disconnect for a few months and now it doesn't do anything. The reset button doesn't respond, the lights are fixed blue all the time, ethernet lights blink but nothing on the router side and it's consuming around 300W.

hmm. would you be willing to send me to tinker with? I had many of these and had zero issues. but I do not have anymore at the present. If I had one to play with, I might be able to solve your problem.

For the interested miners who use the BW-L21, here's some info i found when playing around with this miner.
add /debug.html to your miner address, for example: 192.168.178.45/debug.html. This will show a page with some chinese info with some settings, try it, it won't change anything
Log in with winscp into your miner with user: root and pass: bwcon, then go to usr/app/ and you find yourself in the dir of the mining software.
Check version.txt what kind of version you have. Check conf.default for the config of the miner.
When browsing in some dirs, you will see it runs on a linux dist. specially made for the am335x-evm chip on the board.
That's it.

can annybody help me, he is not updating:
How's your ip.txt file?

@jordytje77
This might be a dumb question, but is your PC set in the same network subnet as the miner ? (192.168.178.x)

There's still no official release of the new firmware so I'll try to share it with you.
It's not as easy has the previous updates, but I've managed to do it with no problem having only a very basic knowledge of unix terminal.
These are the instructions I received via email from hyperbit:
Install sshpass: https://gist.github.com/arunoda/7790979
Install gnu parallel: https://www.google.com/search?q=install+gnu+parallel
If you're using Mac as me you'll need to install brew
firmware files: https://www.dropbox.com/s/indgp8nlnk3372s/2.9.0.tar.gz?dl=0
*please note it's my dropbox link, they sent it to me via email.

These are the instructions I received via email from hyperbit:
Code:
1. You'll need sshpass and parallel installed on whatever machine (UNIX) the script is run on. Links below.
2. tar -xzf 2.9.0.tar.gz
3. cd 2.9.0
4. Edit ip.txt and specify the IP address of the machines you want to update (one per line).
5. ./run.sh
Note, there will be lots of output as each machine is updated.
Some of it may look like failures, this is ok and can safely be ignored.
The updater is built to work across many potential versions and tries to fix various things on the system.
Some of which may already be fixed, so the output reflects that.

those the ones I escrow with main account. Came from europe. Lite in packing. Correct? Did they roi by now?
yes - those are the ones - and I would say I am close to if not made roi by now - depends on when/if I cash out the LTC - nearly 4 LTC since then.

That's the problem with them. Never reaching 550 on pool
very rarely and I mean very rarely do they on the pool reflect the combined hash rate of 1.65 gh/s and if they do it is not for long - so yes, I do agree that is an issue.
other than that the only issue I have is the power usage - the seller stated they ran at 850 watts and not at the advertised 950 watts - mine run at 925 to 950 so the seller was wrong.
that aside, the units otherwise perform issue free. I dont have to restart them continuously, they are not overheating etc

I have three of these miners - my only issue is that on the gui they all read at running between 550 mh/s to 600 mh/s but no matter what pool I try the pool only shows 375 mh/s to 425 mh/s
I am not sure what version fw I have as it is mostly in Chinese which I cannot read but I would love to have the newest official fw, if anyone knows of an official source - not to keen on just downloading random fw though.
***edit***
I found that the fw I have says "BwVersion2.8.0" -- maybe this is the latest fw?

I see, I also have similar problem with non working control boards and good hash boards. I hope I will find solution for those devices, thing is those files exist but I do not know where...
August 06, 2019, 10:45:00 AM
That's over my experience and knowledge to help you further.
I know the issue is on the controller board, but besides a physical examination I can't do much. I found a controller that looked burned and replaced it but still dead. When I change the board with other one it works so I know the hashboards are fine but I don't have any spare controller to use...
