If your NerdMiner is constantly showing zero hashrate and/or rebooting every two minutes, there could be several reasons for this issue. Follow these steps to troubleshoot and resolve the problem:

Step 1: Check Power Supply

The first thing to try, as it's the easiest and most common issue, is to check your power supply. Many problems can be caused by faulty or poor quality power supplies. Here's what you should do:

Use a different USB power plug and a different USB C cable to connect your Nerdminer to the power source. Make sure the cable and plug are in good condition. Unstable or inadequate power can cause your device to reboot or display zero hashrate.

Step 2: Verify Network/WiFi Connection

Another potential issue might be related to your network or WiFi connection. Here's how to troubleshoot this:

Check if the time is correct, check if the Nerdminer is showing a block height and a BTC price as you scroll through the display screens. If you aren't seeing any of these it is likely your WiFi connection is the problem. Try connecting your Nerdminer to a different WiFi network. You can even use your mobile phone's hotspot as a temporary network to see if the issue persists.

If another WiFi network works OK but your primary one that you wish to use doesn't, Check your router has 2.4GHz WiFi enabled.

Its also advised to ensure your router has IPv4 and IPv6 enabled.

Step 3: Check BTC Address Configuration

The BTC address you are using can be the problem depending which pool you are using.

Make sure your BTC address is not a Taproot address. It's recommended to use a SegWit address starting with "bc1q."

Step 4: Consider Pool Configuration

In some cases, the issue could be related to the mining pool you are using. While it's less likely, it's worth checking. A sign that this could be the issue is if the time, blockheight, and BTC price are all updating, but you are getting zero hashrate. Some ISPs may block or restrict access to certain URLs or ports used by mining pools. The easiest way to prove if a specific pool is being blocked is by switching your miner to a different pool and see if this resolves any issues:

If you are experiencing issues with the default pool (public-pool.io), consider switching to an alternative pool, such as VK bit, or CK solo pool, you can do this by going back to the config.
