For a detached office, the TP-Link RE705X-Outdoor is the purpose-built choice because its manufacturer specifies weather resistance and PoE. For an indoor socket near the building, compare the RE705X and RE225BE; the right option depends on the route and construction between buildings.
Quick answer
The TP-Link RE705X-Outdoor is the clearest fit when the extender itself must be installed outside: TP-Link lists IP65 weather resistance and PoE. If you can keep the unit indoors, the TP-Link RE705X offers WiFi 6 and a Gigabit Ethernet port, while the RE225BE adds WiFi 7 features. For a detached building, a wired access point or point-to-point link may suit the layout better than a plug-in repeater.

Best for an exposed outdoor installation
Drawback: Outdoor mounting and cabling need more planning than plugging an extender into an indoor socket.
Official manufacturer image
Best indoor WiFi 6 option near the outbuilding
Drawback: This is an indoor extender; do not place it where it is exposed to rain or damp.
Official manufacturer image
Best WiFi 7 option for a compatible newer network
Drawback: A newer WiFi standard does not overcome a weak link through thick walls or across a long garden.

Best adjustable-antenna indoor option
Drawback: It is an older WiFi 5 class extender and remains intended for indoor use.
Official manufacturer image
Best compact indoor option for a nearby office
Drawback: Its Ethernet port is Fast Ethernet rather than Gigabit, and it is not weatherproof.

Common questions
It can work when the extender receives a solid signal from the router, but distance, walls and glazing can make the link unreliable. For a separate building, assess a wired access point or a dedicated point-to-point system if a repeater cannot maintain a stable backhaul.
Only use a model the manufacturer rates for outdoor exposure and install it as instructed. The TP-Link RE705X-Outdoor is specified with IP65 weather resistance; indoor models should remain protected indoors.
An extender may help when the router signal already reaches towards the office. Mesh can improve coverage within the home, while a detached office may need a wired or purpose-built outdoor link depending on distance and obstacles.
A 2.4 GHz link often travels through obstacles more readily, while 5 GHz can offer more capacity at shorter range. Actual results depend on the router, extender, interference and building materials.
The port provides a wired connection for a nearby device and, on supported models, can be used in access point mode. It does not by itself improve a weak wireless connection between the extender and router.
Keep exploring
A WiFi extender can carry your router signal further, but placement and backhaul matter. Choose a plug-in repeater for a nearby dead zone, powerline WiFi for difficult layouts, or an outdoor-rated unit for a garden.
TP-Link sells plug-in repeaters and powerline kits. Check EasyMesh support, Ethernet needs and the exact UK hardware revision before buying.
TP-Link RE315 is a practical starting point for a standard indoor dead zone. Consider a Wi-Fi 6 device for newer kit, outdoor-rated hardware for a garden, or powerline where a wireless hop struggles.
Sky has different booster products for different broadband generations. Sky Max customers may use a Max Pod; check your account and hub-specific help before seeking a third-party extender.
