**Quectel Pi M1** smart main control board provides one standard **RJ45** port and supports Ethernet communication at 10/100/1000 Mbps.

> Ethernet cable requirement: only straight-through Ethernet cables are supported; crossover cables are not supported.

## Function Usage

### View Network Configuration

DHCP is enabled by default in the system to automatically obtain the network configuration.

1. Enter the `ifconfig` command in the terminal to view the network interface address:

```
ifconfig
```

1. Output example: the `192.168.90.116` shown after `inet addr:` is the local IP address.

## Test the Network

**Run the`ping`****command to test the network connection**

- Run the `ping 8.8.8.8` command. If the ping succeeds and responses are received, the external network connection is normal.

- Run the `ping www.example.com` command. If the ping succeeds, the external network connection is normal and the **DNS** resolution function is working properly.
