Who is this for?

People with a wired backup device

If a NAS, desktop or docked computer can use Ethernet in the loft, an Ethernet-only kit offers a network route without adding Wi-Fi coverage you do not need.

Loft workers who also need Wi-Fi

If laptops or other wireless devices need coverage alongside the backup connection, consider a powerline Wi-Fi extender and check its Ethernet ports separately if your backup device needs a cable.

People unsure about the loft wiring

If you do not know how the conversion is wired, test the router and loft sockets before making powerline part of a backup routine. TP-Link says its adapters will not communicate when placed on different circuits.

What matters when choosing?

Check whether the intended sockets can form a usable link, then decide whether the loft needs Ethernet alone or Wi-Fi as well.

Concern What to check Who this matters to
Wired backup connection Check that the backup device or its dock accepts Ethernet, and that the kit has two adapters and an Ethernet port at the loft end. If my backup device can stay cabled in the loft, I want a direct network route without adding wireless coverage; around 46% of consumers put that wired connection first.
Loft Wi-Fi Choose a kit explicitly described as a powerline Wi-Fi extender; check Ethernet ports separately if a wired device also needs connecting. When I use a laptop and other wireless devices upstairs, I need Wi-Fi as well as a route for backups; for around 27% of consumers, loft Wi-Fi is the primary concern.
Wiring and socket suitability Test the intended router and loft wall sockets, check the adapters’ status indicators and try a representative backup transfer. If the loft conversion’s circuit layout is uncertain, I need to know the link works before scheduling backups over it; around 27% of consumers prioritise that wiring check.

Buying pitfalls

  • Treating the advertised rate as backup speed

    An AV1300 label is not a promise that files will transfer at that rate. TP-Link says powerline performance varies with interference, network traffic, overhead and circuit conditions.

    Try a realistic file transfer between the planned sockets during normal household use before depending on the link for backups.

  • Using an extension lead for the adapters

    devolo advises plugging powerline adapters directly into wall sockets because power strips, extension leads and nearby electrical devices can affect transmission.

    Use wall sockets for the adapters. If you need to keep an outlet available, check for a passthrough-socket model and follow its instructions for anything connected through it.

  • Mixing incompatible powerline standards

    TP-Link states that G.hn powerline devices are not compatible with HomePlug AV and AV2 adapters, even though both use household wiring.

    Check the technology family of every existing adapter before buying units to expand the network.

  • Expecting the adapter to make backup copies

    A powerline kit carries the network connection; it does not supply backup storage or create another copy of a work document.

    Set up and test the backup destination and process separately, then use the powerline link if its tested connection meets your needs.

Brands to consider

TP-Link

TP-Link offers wired HomePlug AV2 kits and powerline Wi-Fi extender kits relevant to a loft connection.

  • TP-Link specifies a Gigabit Ethernet port and integrated passthrough socket for the wired TL-PA8010P KIT.
  • Its advertised AV1300 rate is not guaranteed backup throughput; check circuit suitability and do not combine HomePlug AV/AV2 units with G.hn units.

devolo

devolo’s Magic range includes Ethernet-only LAN kits and Wi-Fi models for rooms that also need wireless access.

  • devolo lists the Magic 1 LAN Starter Kit as expandable within its Magic series; its Magic 2 WiFi 6 next range includes Wi-Fi and Ethernet connections.
  • devolo recommends direct wall-socket placement and warns that nearby electrical devices can interfere with transmission.

NETGEAR

NETGEAR describes powerline as a way to establish a wired or Wi-Fi connection through household electrical wiring.

  • NETGEAR’s guidance makes the circuit condition explicit: both adapters need to be on the same electrical circuit.
  • Check the ports, wireless capability and powerline standard of the particular kit before comparing it with another model.

Frequently asked questions

Will powerline work between my router and converted loft?

It will work only if the intended sockets can form a usable powerline link. TP-Link says its adapters on different electrical circuits will not communicate; interference and network conditions can also affect performance. Test the router and loft sockets before depending on scheduled backups.

Do I need an Ethernet-only kit or a powerline Wi-Fi kit?

Choose Ethernet-only when the loft backup device can remain cabled and you do not need the kit to provide Wi-Fi. If wireless devices also need coverage, consider a powerline Wi-Fi kit and confirm it has the Ethernet ports required by any wired backup device.

Where should I plug in the adapters?

Plug them directly into wall sockets rather than an extension lead or power strip, as devolo advises. After pairing the units, test the intended router and loft positions; if the connection is weak, try another wall socket and check for nearby electrical devices that may interfere.

Can I add a G.hn adapter to my HomePlug AV/AV2 network?

No: TP-Link states that G.hn powerline devices are not compatible with HomePlug AV and AV2 adapters. Identify the standard used by your existing units before adding another adapter.
