Shed, granny flat or metal studio: which WiFi fix actually works

Before you buy anything, answer these three things about the building you are trying to cover:

• How far is it from the house? Same block, or hundreds of metres up the paddock?
• Can you see it from the house? Clear line of sight, or trees, sheds and a rise in the way?
• Does it have power and internet nearby? Mains power out there, and is there a fixed line, or is it genuinely off grid?

Your answers drop you straight onto one of the fixes below. No guesswork.

If the building is within a house length or two and has a power point, the cheapest reliable fix is to put another access point out there and feed it back to the house.

Best: run a cable. Outdoor-rated cable from the house to a second access point, or a mesh node in wired-backhaul mode, gives full-speed WiFi in the outbuilding. Some conduit and you are set for years. The full case for the buried run, and how to do it so it lasts, is in running a cable to the shed.

Good enough: a mesh node. If you cannot run a cable, a mesh system with a node placed near a window facing the house can bridge the gap wirelessly. More fragile and slower than cable, but plug and play. The outdoor extender guide covers what to buy and what to leave on the shelf.

A granny flat is usually this case: close, powered, and sometimes with its own fixed line already. The granny flat internet guide covers when to extend the house connection and when to give the flat its own. Either way you are extending a network you already have, not fighting distance with brute force, and the full how-to walks a close extension through step by step.

Once the building is too far to mesh but you can still see it from the house, stop thinking about WiFi and think about a point to point wireless bridge: a matched pair of small dish or panel radios, one aimed at the other, carrying a solid link hundreds of metres, sometimes kilometres, as long as nothing blocks the path.

• One radio on the house, fed by your internet, and one on the shed, aimed dead at each other.
• At the shed end, plug that into a normal access point and you have full WiFi out there.
• Line of sight is everything. A single tree or roofline in the path can wreck it, so mount high and aim carefully.

This is a proper bit of gear and aiming it well is a skill. For a long or obstructed shot, or a link you are depending on, our sister service Long Range WiFi surveys and installs the bridge rather than leaving you to wing it.

If the problem is not distance from the house but that there is no fixed internet at the property at all, extending WiFi will not help. There is nothing to extend, so you need to bring a connection in:

• 4G or 5G home wireless. A mobile-network modem, and the simplest option if you have decent mobile signal at the site. Check the coverage maps, and better still, stand there and watch the bars on your phone.
• Starlink. Satellite internet for when mobile coverage is poor or absent. It needs a clear view of the sky and draws real power, but it works genuinely remote.

Which one comes down to whether you have mobile signal. For anything properly rural, our sister site Paddock Networks handles rural and satellite connections, and Starlink Rural covers Starlink supply and installation end to end.

Right out on the back paddock with no mains, the constraint becomes power, not signal. You can absolutely put connectivity out there, but everything has to run off a battery topped up by solar:

• A solar panel and battery sized for the gear’s real draw. Starlink in particular is not a low power device, so size the battery for cloudy days, not sunny ones.
• Low power networking kit at the far end.

This is off grid territory and the sizing is the whole game: undersize the battery and it dies every overcast week. That is Starlink Rural territory, where the panel and battery are sized to the site rather than guessed at.

Here is the one that catches everyone. You have a Colorbond or steel shed close to the house, good signal right up to the door, and nothing inside. So you buy a bigger antenna and blast harder from the house. It does not help. It never helps.

A steel shed is a Faraday cage: the metal skin reflects radio and will not let it through. Turning up the power outside just bounces more signal off the outside of the shed. The signal is not weak, it is blocked.

The fix is to stop trying to get signal in and instead put an access point inside the shed and feed it:

• Run a cable in through a gland or gap and plug in an access point inside. Best option.
• If you cannot run a cable, mount one radio of a point to point pair outside the shed, where the signal is fine, and cable it through the wall to an access point inside.

Once the source of the WiFi is inside the metal box with you, it works perfectly. The metal shed WiFi guide goes deeper on getting a fed access point past the steel skin, rather than shouting louder from outside.

The short version, by situation:

• Close, has power: cable or mesh a second access point out there.
• Far, clear line of sight: a point to point wireless bridge, with an access point at the far end.
• No fixed internet at the site: 4G or 5G home wireless if you have mobile signal, otherwise Starlink.
• No power at all: solar, a battery and Starlink, with low power kit.
• Metal shed: an access point inside the shed, fed by a cable or a point to point radio.

Do not just buy a bigger antenna. Work out the distance, the line of sight and the power situation first. Close with power means a cable or a mesh access point out there. Far but visible means a point to point bridge. No internet at the site means 4G, 5G or Starlink. No power means solar and Starlink. And if it is a metal shed, the signal is blocked, not weak, so put the access point inside and feed it rather than blasting harder from outside.

General guidance only: every site is different. For a long or obstructed link, have a point to point specialist survey it, and for genuinely remote or off grid sites, plan the power and the connection together before buying gear.
