Bought used Dragonmint T1. Cant Find the IP address

[cryptosai]

Hello Guys,

I recently bought a used dragonmint miner. I powered it on and everything sounds like it is working. But there is a major problem :

1. I cant find the ip address of the miner on the ip scanner even after hard reset & ip reset.

2. I tried connecting the lan cable directly to miner. It gives me 169.X.X.X which means it is not connecting.

FYI I am doing this at work so as to get free electricity.

Your help is much appreciated.


So with the help of previous posts I was able to find the IP address and access web GUI but for some weird reason it is start at 9 Th/s and then keeps going down.

Also, the miner infor shows only 2 and they start with alive but within 5 minutes goes to dead.

By connecting the dots, I am willing to bet on the router at your work place is blocking your miner , honestly any average network engineer would configure the router to block such "weird activities" such as mining.

I don't want to sound mean, but you should really not be mining at work unless you are allowed to, and if that is the case, ask the IT guys in your company to check if the router is dropping any packets coming in or going out from your miner.

Try to reset the miner and scan it again make sure it's connected to the router properly.

Here's the method on how to reset the miner below.
- Find the reset/Ip scanner button at front of the miner
- push and hold the button for 15 sec. Then release.
- scan the miner's IP again and check.

If you can't still scan the IP address or getting 169.x.x.x try to boot the miner in SD card with Braiins Os and scan the IP again.
Braiins OS documentation can be found here https://docs.braiins-os.org

I was thinking on this and maybe there are many computers connected on the same router.

Don't forget to increase the IP ranges on IP scanner...

I would treat this as an normal network device :

- Remove it from current network.
- put it in an known network you manage yourself ( f.e. your home network )
- check if it takes a IP from the DHCP server
- if it does you know it has DHCP IP enabled, and so you know it will try to ask for an IP in your work's network.
- if it doesn't it is on an fix configured ( or factory default ) IP address. Try to find it.

Remember that 'work' networks look to the device before giving out a IP adress by DHCP !! ( By layer 2 communication : is it an known device ? What kind of device ? Is it allowed by company policy ? ... )

Maybe if we all learn to read the post / edits and updates this forum will be a much better place.

before anyone commented , OP edited the post and added this part.

So with the help of previous posts I was able to find the IP address and access web GUI but for some weird reason it is start at 9 Th/s and then keeps going down.

Also, the miner infor shows only 2 and they start with alive but within 5 minutes goes to dead.

So this is no longer "I can't find my miner's IP" anymore, it's totally a different problem , the miner starts , hashes for a while and then stops, which only means a few possibilities.

1- The router blocks the miner / pool after x amount of packets / x amount of time
2- Temperature gets way too high and the miner goes into idle to protect itself against toasting
3- Power supply is failing

These are the once on top of my head , there are a few others, but by analyzing his post, I am leaning towards the first option, so please READ the post and kindly stop asking him to troubleshoot a problem he does not have in the first place.
