How to Connect Your Avalon Nano 3S with a Wired Ethernet Connection (No WiFi Needed)

The Avalon Nano 3S is a fantastic home Bitcoin miner — super quiet, compact, and powerful enough to earn real BTC from your living room. But like most home miners, it uses WiFi for network connectivity by default.

What if your miner is in a basement, garage, or a room where WiFi is weak or unstable? Or maybe you just prefer the reliability of a wired connection?

Good news: you can bypass WiFi entirely and connect your Avalon Nano 3S via a wired Ethernet connection using a simple USB to Ethernet adapter. Here is how.

Why Go Wired?

Before we get into the setup, here is why a wired connection might be better for your mining rig:

  • Stability — No WiFi dropouts. Your miner stays connected 24/7.
  • Lower latency — Less chance of stale shares when submitting work to your mining pool.
  • No signal interference — Thick walls, distance, or other devices will not affect your connection.
  • Easier troubleshooting — One cable, one connection. No fiddling with WiFi credentials.

What You Will Need

  • An Avalon Nano 3S Bitcoin miner
  • A USB to Ethernet adapter (USB-A, standard 10/100/1000 Mbps — widely available on Amazon)
  • An Ethernet cable (Cat5e or Cat6)
  • A router or switch with a free Ethernet port
  • Your mining pool details (URL, wallet address, worker name)

Step-by-Step Setup

Step 1: Get the Adapter

Any standard USB-A to Ethernet adapter will work. These are the same adapters used for laptops without Ethernet ports. They are inexpensive (usually $10–15) and readily available on Amazon, Newegg, or any electronics store.

Step 2: Plug It In

  1. Connect the USB end of the adapter to the USB port on your Avalon Nano 3S.
  2. Connect one end of your Ethernet cable to the adapter.
  3. Connect the other end to your router or switch.
  4. Power on your Avalon Nano 3S.

The Nano 3S will automatically detect the wired connection and prefer it over WiFi. No additional configuration is needed on the miner itself.

Step 3: Configure Your Mining Pool

  1. Access your miner dashboard (find its IP in your router DHCP list).
  2. Log in with your credentials.
  3. Navigate to the Mining Pool Settings.
  4. Enter your pool URL, wallet address, and worker name.
  5. Save and restart the miner if prompted.

Step 4: Verify the Connection

Once the miner is running, check the dashboard. You should see:

  • A valid IP address from your router DHCP range
  • Active network traffic (data in/out)
  • Your miner hashing and submitting shares

If the miner is not connecting, verify DHCP is enabled on your router, or try rebooting the miner with the Ethernet cable plugged in from the start.

Pro Tips

  • Static IP recommended — Set a static IP for your miner in your router settings. This makes it easier to access the dashboard every time.
  • Keep a backup — WiFi is still an option. If you ever need to move the miner, just disconnect the Ethernet cable and it will fall back to WiFi automatically.
  • Check your cable — A damaged Ethernet cable can cause packet loss. Use a known-good cable if you experience disconnects.

Frequently Asked Questions

Will this void my warranty?

No. Using a USB to Ethernet adapter is a standard accessory, just like connecting a keyboard or mouse. It does not modify the miner in any way.

Does it work with all versions of the Nano 3S?

Yes. This works on the Avalon Nano 3S, the Avalon Nano 3, and likely future models in the Avalon Home series.

What if my adapter is not recognized?

Most USB to Ethernet adapters use standard chipsets (AX88179, RTL8153) supported by the miner Linux-based firmware. If you encounter issues, try a different brand — Anker, Ugreen, or Cable Matters adapters are known to work reliably.

Can I use a USB hub to connect both the adapter and a USB drive?

The Nano 3S has a single USB port, so you would need a powered USB hub. However, for best reliability, connect the adapter directly to the miner USB port.

Final Thoughts

The Avalon Nano 3S is already one of the most convenient home miners on the market. Adding a wired Ethernet connection makes it even more reliable — especially if your WiFi setup is less than perfect. For the cost of a $10 adapter and a few minutes of setup, you get a rock-solid mining connection that just works.
