Internet in a rented Maresme villa: fibre, 5G and Starlink

The listing says fibra. Then you arrive, the router is in a cupboard behind a 40 cm stone wall, and the video call dies every time someone opens the oven. Fibre coverage in Catalonia is genuinely good. The last forty metres are the problem.

Why a hillside urbanización is not Barcelona

Very-high-capacity fixed networks reached about 93% of Catalan households already in 2020, and even in the least populated parts of the region the figure sat around 86%, well above the Spanish average at the time. Nationally, FTTH passed 95% of homes by mid-2025. On paper, the Maresme is covered.

In practice, coverage is calculated per building and the database does not always know your house exists. A plot on a private road in Supermaresme, a masia above Òrrius with no street number, a villa at the end of a 90-metre driveway: all three can show as covered on the map and as no coverage when the operator types in the address. Sometimes the previous tenant took the ONT and the router with them, because the contract was theirs.

There is also the Wi-Fi question, which is separate from the fibre question and gets confused with it constantly. Fibre arriving at the house says nothing about whether the signal reaches the bedroom on the other side of two stone walls. A 250 m² villa with thick walls will eat the operator's free router in one room.

The three connections that actually exist

Fibre is still the default and the best value. Movistar sells 1 Gb symmetrical at €29.90 a month for the first year and €45 after that, with installation free and no permanence in the current offer; Orange sits in a similar band, roughly €30–40 promotional and €40–50 standard. Both need a technician, a hole in a wall and, on a private road, someone who can open the gate at 09:00 on a Tuesday.

5G home internet is the quiet winner where fibre never arrived. No trench, no gate, no permission: a receiver in the window and a contract. Real speeds on a good mast run 100–300 Mbps down, which is plenty for two people on calls. The catch is that the mast matters more than the operator's map, and a house in a valley behind Cabrils is not the house on the ridge above it.

Starlink is the third option and the one people ask about most. In Spain in 2026 the residential plans sit at €35, €45 and €65 a month depending on the tier, with the kit and any professional installation on top of that. Latency is roughly 25–60 ms, which is fine for Zoom and noticeable in fast games. It needs a clear view of the sky: a pine canopy, a tiled roof overhang or the wrong side of a hill will cost you the connection exactly when the north wind brings rain.

Five checks before you sign

• Type the exact address into the operator's coverage page, then try it again without the house number. If the number is what breaks it, ask the owner which operator the neighbours use, because on a private road there is usually one that already has fibre in the ground.
• Ask for the current contract and a speed test screenshot taken at 21:00, not at 11:00. Evening is when the street's shared capacity shows its real face.
• Ask where the ONT and the router live, and whether there are Ethernet sockets in the bedrooms or in whatever room you will work from. A cable beats a mesh node every time, and the socket is the thing nobody remembers to check.
• Ask who orders the line if there is none, who pays the alta, and what happens if the technician needs three weeks. In August, three weeks is the whole month.

Wi-Fi inside the house is your purchase, not the operator's

A mesh system with three nodes costs €200–400 and covers a normal villa; powerline adapters are cheaper and work badly across different electrical circuits, which a house with an old board and an annex often has. If you work from the garden, a cable to an outdoor access point is the only version that survives a stone wall and a swimming pool.

Buy the mesh yourself and keep it. It is yours, it moves with you, and it costs less than a month of arguing with an owner about who should pay for better coverage in a house he does not live in.

The contract, the bill and the hole in the wall

Two models exist. Either the line stays in the owner's name and you reimburse the monthly invoice, or you contract it yourself with your NIE and Spanish bank account. The first is simpler and keeps the service alive between tenants; the second gives you the invoice in your name, which matters if you are autónomo and want to deduct it.

Installing a line means a technician, a drilled hole and a fixed element in the house, so article 23 of the LAU applies: written consent from the owner. In practice nobody objects to a fibre box, but get the consent in a message rather than a nod at the gate, and agree in writing whether the line stays when you leave. A 12-month commitment signed in month ten of a lease is a bill you will pay after you have moved out.

A fallback that costs €20

• Keep a 4G or 5G router as a backup if you work from home. It costs €60–150 and saves the day when a digger cuts the fibre on the Camí de la Serra, which happens more often than the operators admit.
• Check mobile coverage inside the house, not on the terrace. A villa that shows four bars at the pool can show one bar in the kitchen, and the kitchen is where the router usually is not.
• Ask what the operator's repair commitment is. Twenty-four to forty-eight hours is normal, but a private road adds a gate, a key and sometimes a neighbour who has to be at home.
• If the house has a Smart TV, a pool pump on Wi-Fi and a video doorbell, count the devices. Ten connected things on a 100 Mbps line are fine; ten on a 4G router with a 200 GB cap are a monthly argument.
