Unable to connect to the Internet or find IP of the miner

The solutions in this article applies to all Antminer.

1. Connect to the Internet or Network.

Place miners in alternative networks. If it works normally, there may be a problem with the network itself. Please contact your Internet provider to confirm whether their service is normal.

If the network is good, it could be the modem or router not working. Check the power supply of the router (maybe the power plug is loose), whether the cable is tightly connected, the Internet signal and the LAN port by checking the indicator light on the modem or router.

Or the Ethernet cable is not plugged in correctly or is malfunctioning. You need to test the Ethernet cable (Recommend Network cable finder).

2. Router or switcher settings.

Check the router or switcher to see if any network configuration is disabled.

If unsure, consult a professional network engineer about rectifying network configurations.

Try to log in to the router settings page and check the IP address displayed in the "Connected Devices" list to see if it can detect your miner.

If not, you can reset the router, or check the router manufacturer’s website and see if there is a firmware update available.

Ask the router manufacturer how many devices can be connected to your router. Some routers have restrictions on the number of connected devices, which may be the reason why your miner cannot access the Internet.

3. The network configuration of the mining unit conflicts with the IP address.

Only DHCP server is allowed. Make sure that DHCP is enabled on your network, and if it is found to be disabled, enable it. If your miner has set a static IP address, please ignore this item.

• How to set my miner as a static IP address?

When your network is static, the MAC address can be used for binding. Our miners cannot connect on a static network, so if you enable it on the network, please disable MAC binding.

Check if your network provider has accidentally disabled the mining pool port. There may also be problems with the mining pool URL or unstable mining pool server. In this case, the miner may be connected to the Internet, but will not appear in the mining pool. The kernel log will show this problem.

4. Restart the miner.

The miner has not started completely or started correctly. Just like a PC, for the operating system to start and work normally, multiple programs and tasks need to be completed.

Try to restart the miner several times and check whether the problem has been solved each time.

• How to restart my miner?

Your computer should be connected to the same network as your miner. Every time you restart the miner (or press the IP reporter), your IP address may change.

5. The control board is restored or reset to factory settings.

You can reset the miner first.

• How to reset the miner?

If restoring factory settings does not help, the control board may be faulty. Please refer to the following to learn how to troubleshoot or restore the control board:

• Check control board problems.

Certain malware attacks may damage the control board program.

• How to prevent and eliminate malicious attacks?

Of course, if the problem still cannot be solved, please repair or replace the control board.

If you still cannot resolve these issues, please contact us for further assistance.

6. All brand new miners unable to obtain IP address

Solution:

(1). Check whether DHCP is enabled on the network. It must be enabled.

(2). Check whether MAC binding is enabled on the network. It must be turned off.

(3). Check whether the router connection and settings are normal.

7. Some new miners cannot obtain IP addresses

Solution:

(1). Check whether the switch can connect to the Internet normally. Connect a normal computer to the switch through a network cable to see if it can access the Internet normally.

(2). Check whether the IP pool range is sufficient. As shown in the figure below, there are only 99 IPs that can be automatically assigned by default (a maximum of 254 can be set).

(3). Consult the router manufacturer to determine how many devices the router can carry. For ordinary home routers, the maximum number of available IP addresses can be set to 254. However, due to hardware issues, the number of ordinary routers online simultaneously only ranges from 10 to 50. Basically, there is no data about capacity, and it’s required to consult the manufacturer. Nowadays, only some of the more professional home smart routers will have relevant machine capacity data, so you need to pay attention when purchasing.

8. All miners are unable to mine. The miner has obtained an IP, and the computer can access the Internet normally.

Solution:

(1). Check whether the network configuration is disabled. Generally, routers have whitelist settings or Internet access policy restrictions, which can be restricted for specific websites or Internet access methods. This problem is relatively professional and requires network engineers to troubleshoot.

(2). Check whether the network operator has closed the mining pool port. Generally, the corresponding port is behind the mining pool. If the operator disables the corresponding port, it will only affect mining, not the Internet. Port issues need to be resolved by contacting the network operator's customer service.

(3). Check whether the mining pool and miner settings are normal.

(4). Take two machines to other networks. If they work properly, the network has a problem here.

9. Some miners cannot mine while in use

Solution:

(1). Check whether the router or switch is normal.

(2). Check whether the power is normal.

10. After the miner changed location, the IP could not be found

Solution:

(1). Reset the miner. When the miner is powered on, use the needle to poke the reset button for about 5 seconds. Both of the red and green indicator lights will turn off, and they will be reset. Wait for the miner to restart.

(2). Reset the miner. When the miner is powered on, push RESET with a needle for about 5 seconds, the traffic light will go out, and it will be reset now. Just wait for the restart.
