### Ethernet (when Ethernet support is compiled in)
Ethernet support is available on RAK4631 boards with a RAK13800 (W5100S) Ethernet module. Use the `_ethernet` firmware variants (e.g. `RAK_4631_repeater_ethernet`) to enable this feature.
---
#### View Ethernet connection status
**Usage:**
- `eth.status`
**Output:**
- `ETH: <ip>:<port>` when connected (e.g. `ETH: 192.168.1.50:23`)
- `ETH: not connected` when Ethernet is not active
**Notes:**
- Available on repeater and room server firmware only. Companion radio ethernet firmware does not expose a CLI.
- The Ethernet interface obtains an IP address via DHCP automatically on boot.
- A TCP server listens on port 23 (default) for CLI connections.
- Connect with any TCP client (e.g. `nc`, PuTTY) to access the same CLI available over serial.

### 7.8. Q: How do I use Ethernet with a RAK4631?
**A:**
MeshCore supports Ethernet on RAK4631 boards using the [RAK13800](https://docs.rakwireless.com/product-categories/wisblock/rak13800/datasheet/) WisBlock Ethernet module (based on the W5100S chip).
**Hardware required:**
- RAK4631 WisBlock Core
- RAK19007 or RAK19018 WisBlock Base Board (with an available IO slot)
- RAK13800 WisBlock Ethernet module
- Ethernet cable connected to a network with a DHCP server
**Firmware:**
Flash one of the Ethernet-enabled firmware variants:
- `RAK_4631_repeater_ethernet` - Repeater with Ethernet CLI access
- `RAK_4631_room_server_ethernet` - Room server with Ethernet CLI access
- `RAK_4631_companion_radio_ethernet` - Companion radio over Ethernet (replaces BLE)
**Connecting:**
- The device obtains an IP address via DHCP automatically on boot.
- For repeaters and room servers, connect to the device on TCP port 23 using any TCP client (e.g. `nc <ip> 23` or PuTTY in raw mode). This gives you the same CLI available over serial/USB.
- For companion radio firmware, the Ethernet interface replaces BLE as the transport to companion apps. Connect on TCP port 5000 (same as the WiFi companion radio).
- Use the `eth.status` CLI command to check connection status and see the assigned IP address.
