Home Wi-Fi is designed for indoors. Step outside and the signal must get through the exterior wall, twice as thick and often reinforced concrete, then travel through open air to the back patio, gazebo, or poolside. The result is one flickering bar. This guide covers when moving the router is enough, when you need an outdoor access point, and how to install one so it survives years of rain and heat.

When no new hardware is needed

If the outdoor area adjoins the room the router is in, a front patio beside the living room, a balcony beside the bedroom, moving the router near the window facing it is often enough. Ordinary glass barely weakens signal; walls are the problem, not windows. Placement guidance in router placement. More than one wall, or more than 10 metres outside, needs its own transmitter outdoors.

Choosing an outdoor access point

  • IP65 rating or higher. First digit = dust, second = water. IP65 withstands rain spray from any direction; IP67 brief immersion. Under a roof, IP55 is enough.
  • PoE. Outdoor access points are almost always powered over the LAN cable, there's no socket on a garden pole, and there shouldn't be. Make sure a PoE injector is included or buy one; explained in the PoE guide.
  • Dual-band with good 2.4 GHz. Outdoors, 2.4 GHz does the work: long range and gets through trees. 5 GHz helps on a nearby patio.
  • Omni antenna pattern for a garden, sector/directional for one direction. Round/cylindrical units radiate in a circle, suited to the middle of a garden. Flat panel units radiate to one side over ~90–120°, suited to a house wall facing the garden, so power isn't wasted into the house. Beam shapes are explained in the external antenna guide.
  • Same brand as the indoor access points if using a mesh system or central controller, so devices move smoothly from inside to outside, see roaming between access points.

Installing it properly

  • 3–4 metres high, facing the target area, with no direct obstruction. Too low, and fences and plants block it; too high, and phones below are outside the antenna pattern.
  • Under an eave or roof where possible, even though the unit is rain-proof. What fails most often isn't the unit but the RJ45 connector letting water in, fit the supplied connector gland, and form a downward cable loop (drip loop) before the connector so water drips off rather than running in.
  • Outdoor cable. Use LAN cable labelled outdoor or UV-resistant; indoor cable cracks within a year under tropical sun. Maximum 100 metres including PoE. See choosing LAN cable.
  • Surge protection. A LAN cable run to a pole in an open garden is a lightning path into every device in the house. Fit an Ethernet surge protector where the cable enters the house and earth it properly, it costs little compared to the router, switch, and PCs it protects. On a metal pole, earth the pole too.
  • A different channel from the indoor router, and if the outdoor area is close to neighbours, lower the transmit power so you don't interfere with them, or invite unwanted users. See choosing a Wi-Fi channel.

When it's far: a separate building

For a pavilion, second house, or shed at the far end of the plot more than 30–50 metres away, an ordinary access point on the house wall isn't enough. Use a pair of point-to-point units facing each other, then an ordinary access point in the target building. The guide is connecting internet between buildings; if the cable route crosses someone else's land, first read internet cable across a neighbour's property.

A security note

Wi-Fi that reaches the garden also reaches the street out front. Make sure the password is strong, WPS is off, and consider a separate guest SSID for outdoor areas guests use often. Basics in securing a home router; if you later spot unknown devices, see finding out who's using your Wi-Fi.

Patio beside the router's room: move the router to the window. Beyond that: an IP65 outdoor access point with PoE, mounted 3–4 metres up under an eave, outdoor cable with a drip loop and surge protector, a different channel from indoors, power set to just enough. A distant separate building: point-to-point, not an ordinary access point.

Frequently asked questions

Can an outdoor access point be exposed to direct rain?

Rated IP65 or higher, yes. Even so, mounting under an eave or patio roof extends its life, what usually fails first isn't the unit but the cable connector letting water in. Use the gland or connector cover supplied.

Can I just put an ordinary router near a window?

For a front patio adjoining the living room, often yes, ordinary window glass barely weakens signal. For a back garden blocked by the kitchen and bathroom, or a gazebo 15 metres from the house, no.

How far does an outdoor access point reach?

In open space with no obstacles, 50–100 metres for phones on 2.4 GHz, about half that on 5 GHz. Dense trees, brick fences, and pools reduce it. The limit is usually not the transmitter but the phone's transmit power to reply.
