USB-to-LAN adapters are listed here.
Download the latest IPFire (Flash Image) and flash it to an MicroSD card.
| Note! |
|---|
| The ARM flash image is configured for serial console at default |
• If using HDMI & USB Keyboard: edit the uENV.txt file and change SERIAL-CONSOLE=ON to OFF |
• If using the serial console: edit the config.txt file and add enable_uart=1 to the end |
After flashing the SD card install it into the Raspberry Pi, connect the cables and power supply, and power it up. At the start of booting you'll see:
Net: No ethernet found.

USB0: Core Release: 2.80a

The Raspberry Pi 3 Model B+ (Raspi 3B+) will normally boot within 70 seconds. Once the Raspi 3B+ is fully booted begin to follow the steps here.
| Note! |
|---|
| If the IPFire sits (forever) with just the IPFire logo (1 logo for each core), then see Note! above. The IPFire may using HDMI & Keyboard while configured for serial console. |
| If the IPFire sits for more than 3 to 4 minutes it may be trying to locate a driver for an unknown USB device. Unplug the unknown device and reboot the Raspberry Pi. |
On-board Ethernet and WiFi
In the IPFire setup Extended Network Menu, the on-board Ethernet port is known as usb: Standard Microsystems Corp. SMSC95. And the wireless/WiFi is known as sdio: brcmfmac.
