The Ethernet adapter is designed for iPhones with an Apple Lightning port, which includes all models from 5-14. It is not compatible with iPhone 15 or newer models.

Yes. The adapter is designed to let you connect your iPhone to wired Ethernet, so you can use a wired internet connection while Airplane Mode is enabled and wireless connections are switched off.

Yes — you can still make internet-based calls while your phone is in Airplane Mode and connected to Ethernet.

Apps such as WhatsApp, FaceTime Audio, Signal and Messenger can continue to work through the wired Ethernet connection.

However, standard mobile network calls and SMS may not work while Airplane Mode is enabled, as this switches off the phone’s cellular connection. If you need to receive normal calls, you can simply turn Airplane Mode off when required.

Not if you choose the complete bundle. The TP-Link powerline kit uses your home’s existing electrical wiring to bring an Ethernet connection closer to where you use your phone.

The easiest way is to switch your phone to Airplane Mode, which disables its main wireless connections.

For extra reassurance, you can also check that Wi-Fi, Bluetooth, Mobile Data and AirDrop are switched off.

The complete bundle includes:

• 1 × Rowland Ethernet Adapter
• 1 × TP-Link AV1000 Gigabit Powerline Starter Kit (Contains 2 UK-plug powerline adapters)
• 2 × 2-metre Ethernet cables

The adapter-only option is suitable if you already have an Ethernet connection available nearby.

The complete bundle is designed for homes where the router or Ethernet socket is further away, as the TP-Link powerline kit can carry the network connection through your home’s electrical wiring.

One TP-Link unit connects near your router, while the second is plugged in closer to where you use your phone. The connection is carried through the home’s existing electrical wiring, helping you avoid running a long Ethernet cable across the house.

The included TP-Link kit uses the HomePlug AV2 standard and has theoretical powerline transfer rates of up to 1000 Mbps.

Actual speeds can vary depending on your broadband connection, electrical wiring, distance and network conditions.

No. The purpose of the adapter is to provide a wired Ethernet connection to your iPhone, so Wi-Fi does not need to remain on when the wired connection is being used.

No. If you still want a wireless option available elsewhere in your home, you can leave Wi-Fi enabled on your main router and simply switch Wi-Fi off on your phone when using the Ethernet connection.

The main router is usually positioned some distance away from your body, whereas a mobile phone is often used in very close proximity for extended periods. RF measurements can also vary significantly depending on the device, signal strength and how it is being used.

For this reason, if your aim is to reduce your personal wireless RF exposure, reducing the wireless connections being transmitted directly from the phone can be a practical place to start.

The adapter gives you the option of using a wired internet connection instead of Wi-Fi on a compatible Lightning iPhone. The page demonstration compares the same phone using wireless connections with the phone connected by Ethernet and wireless connections switched off.
