Check the downstairs router’s placement before adding equipment: walls and other obstacles can weaken the signal reaching an upstairs room. An extender needs a strong signal at an intermediate spot; mesh suits coverage gaps across several rooms, while powerline depends on suitable electrical circuits and an upstairs access point needs Ethernet. If you replace the router or add mesh, check how it will work with the existing broadband equipment.
If one bedroom or study is affected, check whether the router still provides a usable signal partway upstairs. TP-Link’s extender placement guidance makes that intermediate signal central to choosing a wireless extender.
If coverage drops in several rooms or devices move between floors, consider whether a multi-node mesh system fits the layout. Check node placement and how the system connects to the existing router.
If Ethernet can reach upstairs, a compatible access point can provide Wi-Fi there without relying on the weak wireless link between floors. If running cable is impractical, powerline is worth considering only after checking the intended sockets.
Start with router placement, then assess the affected rooms, the signal at possible equipment locations, and whether Ethernet or suitable electrical sockets offer another path upstairs. Ofcom notes that objects and building materials can weaken Wi-Fi.
| Concern | What to check | Who this matters to |
|---|---|---|
| Several rooms need coverage | Check mesh node placement and whether the system can work with the retained router in the intended mode. | If Wi-Fi drops in several rooms as I move between floors, I need coverage beyond one upstairs spot; around 31% of consumers put multi-room coverage first. |
| A difficult path between floors | Check whether Ethernet can reach an upstairs access point and how that device is powered. | Where walls or floors obstruct the wireless path, I would rather bring the connection upstairs by cable; roughly 25% of consumers make a wired path their main priority. |
| One room has weak Wi-Fi | Find an intermediate position where an extender can still receive a strong router signal. | If only my upstairs study struggles, I want to try a targeted fix without changing the whole network; around 19% of consumers prioritise single-room coverage. |
| Using existing electrical wiring | Confirm the intended sockets meet the kit’s circuit requirements and that it provides the needed upstairs connection. | When I cannot run Ethernet upstairs, I want to assess whether the household wiring offers another route; approximately 13% of consumers put this option first. |
| Keeping the existing router | Check the exact equipment’s router or access-point mode and how it connects to the broadband gateway. | If the ISP router must remain in place, I need added coverage without an unsuitable network setup; around 12% of consumers make router coexistence their primary concern. |
An extender also needs to receive the downstairs signal. TP-Link advises positioning one roughly halfway towards the weak area, where the incoming signal remains strong.
Check a possible intermediate position before buying. If no suitable position exists, consider a route that does not depend on that same wireless hop.
TP-Link specifies a same-circuit requirement for its powerline equipment, and the home’s electrical environment can affect the connection.
Check the intended downstairs and upstairs sockets against the chosen kit’s requirements before relying on powerline for the room.
Operating mode determines which device handles network routing. For TP-Link Deco, the main unit needs a physical connection to the existing modem or router; it does not wirelessly repeat a non-Deco router as its main node.
Confirm the exact model’s connection and operating modes, then decide whether the ISP router will remain the gateway.
Ofcom explains that objects and building materials weaken Wi-Fi, so a stated coverage area cannot establish how well a signal will cross your particular floor.
Assess wall construction, equipment positions and the available wired or electrical routes alongside any manufacturer figure.
Its extender, powerline and Deco mesh ranges cover several possible routes to an upstairs room.
Relevant when considering a compatible router for a wired upstairs access point or another supported operating mode.
A mesh range to consider when coverage is needed across multiple rooms.
A reference point for a planned, Ethernet-connected upstairs access point.
These choices cover multi-room mesh, a wireless extender for a single weak area, and a powerline Wi-Fi kit. Which route fits depends on the signal between floors, the existing router and, for powerline, the intended sockets.

Consider this three-unit mesh system when several rooms need Wi-Fi coverage. Check how the BE22 connects to your existing broadband router and which operating mode your setup requires.

Consider this range extender for one weak upstairs area if the router’s signal remains strong at an intermediate position. Check that position before relying on a wireless connection to the room.

Consider this powerline Wi-Fi kit if a wireless link between floors is difficult and running Ethernet is impractical. Confirm that the intended sockets meet the kit’s circuit requirements; AV1300 is a product designation, not a promised speed in the upstairs room.
Yes, check whether a better position improves the upstairs signal before adding equipment. Ofcom notes that objects and building materials weaken Wi-Fi; where the broadband connection allows, try a more central, raised position away from sources of obstruction or interference.
It can help only if it receives a usable signal somewhere between the router and that room. TP-Link advises placing an extender roughly halfway towards the weak area, rather than inside the dead zone; if no suitable position exists, assess a wired or other backhaul route.
Some mesh systems can work alongside an existing router, but the connection and operating mode matter. TP-Link says Deco supports router and access-point modes; its main unit needs a physical connection, so check the exact mesh model and decide which device will handle routing.
Powerline is an option when the intended sockets meet the kit’s electrical requirements, but it does not guarantee the same connection as a direct Ethernet run. TP-Link specifies a same-circuit requirement for its powerline equipment, and the electrical environment can affect results.
