Our services

Mesh Wi-Fi Installation

Eliminate WiFi dead zones for good with a properly surveyed, professionally placed mesh network, even through thick stone walls, tiled floors and multi-storey villas.

NAS & Backup Setup

Centralised NAS storage with automatic, scheduled backups and RAID redundancy, so one failed hard drive never means lost photos, invoices or family files.

Cloud Storage Setup

Secure, accessible cloud storage and sync setup across Google Drive, iCloud and OneDrive, so your files back up automatically across every phone, tablet and computer.

Finca & Thick-Wall WiFi

Mesh WiFi coverage engineered specifically for thick stone-walled fincas, villas and larger rural properties across the Marina Alta and Costa Blanca.

Router & Firmware Setup

Secure router configuration, password hardening and firmware updates that close known vulnerabilities on your existing router or modem.

Router & Modem Configuration

Optimised channel selection, QoS settings and firmware tuning on your ISP-supplied router or modem, squeezing out every extra Mbps it can deliver.

VLAN & Guest Network Setup

Separate guest, work and smart-device traffic on secure VLANs, ideal for holiday rentals, offices, smart homes and anyone sharing WiFi with guests.

Ethernet & Powerline Backhaul

A wired Ethernet, powerline or MoCA backbone for mesh units when WiFi signal alone can't reliably reach every room, office or outbuilding.

Smart Speaker & IoT Connectivity

Reliable, interference-free network setup for smart speakers, cameras, doorbells and other WiFi and Zigbee connected devices around the home.

Speed Test & Bandwidth Optimisation

Independent speed tests measuring download, upload, ping and latency, followed by router, channel and plan optimisation to fix consistently slow internet.

Starlink & Satellite Internet Setup

Full Starlink dish alignment, router configuration and WiFi distribution for remote fincas, mountain properties and villages with no fibre or ADSL coverage, including obstruction checks and speed testing after install.

Fibre & ADSL Router Installation

Fibre-optic and ADSL router installation, line testing and speed optimisation for Movistar, Vodafone, Orange and other Spanish providers.

VPN Setup for Secure Remote Access

Secure VPN setup for encrypted remote access to your home or office network, ideal for remote workers, business owners and frequent travellers.

Segmented business WiFi with a branded guest portal for shops, offices, restaurants and holiday rentals, keeping guest traffic separate from your own network.

Benidorm
