In recent years the only way to connect an iPhone to ethernet has been to plug together a handful of adapters — a USB camera adapter, a USB hub, a USB ethernet adapter, and an iPhone power adapter (plus, of course, a Lightning to USB cable).

If you plugged all of these items together in exactly the right order you could get things to work. But this created a large mess of adapters and cables!

The new 2nd generation ethernet adapters from Redpark offer a much easier approach.  Two versions of the adapter are available. One uses Power over Ethernet (PoE) as the power source. The other uses an AC power adapter as the power source.  Both of these adapters are licensed under Apple’s “Made for iPhone” (MFi) program.


Connect iPhone to Ethernet in 3 Easy Steps:

1 – Connect the Redpark ethernet adapter to power

AC power:  If you have a local AC power outlet plug the Redpark adapter into the power outlet using the power adapter that Redpark provides.

PoE power:  If you are using power over ethernet (PoE) as the power source use an ethernet cable to connect the Redpark adapter to a PoE enabled switch or PoE injector.   A Cat 5e or Cat 6A ethernet cable is recommended.

2 – Connect the Redpark ethernet adapter to the iPhone

Use a Lightning to USB Micro B cable to connect the ethernet adapter to an iPhone.  Redpark offers this cable in several lengths. Or you can use a Lightning to USB Micro B cable made by other brands (as long as the cable is MFi-certified).

3 – Configure the ethernet connection using the Settings app on your iPhone

Once the ethernet adapter is connected to power and to the iPhone “Ethernet” will appear in the Settings app on the iPhone.   It will be located in between “Wi-Fi” and “Bluetooth” as shown below.  (Requires iOS 10 or later.)

Select “Ethernet” in order to access the ethernet configuration details.  The Ethernet connection can be configured to use either DHCP or a static IP address. The default is DHCP and this does not need be revised in most instances.  If you need to use a Static IP address please enter the configuration settings for your device and network.

The ethernet connection is now ready to use!


How the Ethernet Adapter Works

The Redpark ethernet adapters are a specialized version of USB 2 to Gigabit Ethernet Adapter.  They make use of support for ethernet that is built into the iOS operating system beginning with iOS 10.  This means that the ethernet connection is available to be used by any iOS app!

The adapters communicate with the iPhone using Hi-Speed USB and support connection to 10/100/1000 ethernet networks.  When connected to a Gigabit ethernet network the adapter will provide bandwidth up to 225 Mbps.

These adapters also charge the iPhone. There are two versions of the adapter available:
