Setup Ethernet

The Raspberry Pi 4B has both wired and wireless ethernet. To use the wired connection for a Mesa Ethernet card you need to setup a static IP address and use the WiFi connection to ssh into the Rpi4.

To get a list all available WiFi networks

sudo iwlist wlan0 scan

Configure the WiFi SSID and Password

sudo raspi-config

Then get the broadcast address of the WiFi

sudo ifconfig

wlan0 is what you’re looking for, note the inet address is the one you use to SSH from another PC into the RPi4.

wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
      inet 192.168.1.67  netmask 255.255.255.0  broadcast 192.168.1.255

From another PC you can SSH into the Rpi with the inet address like this

ssh 192.168.1.67

To setup the static IP for eth0

sudo nano /etc/dhcpcd.conf

At the bottom of the file is an example for setting up static IP. Change the eth0 lines to match this

interface eth0
static ip_address=10.10.10.11/24

Ctrl X, Y, Enter to save your changes.

Now reboot so the changes take effect.

sudo reboot
