Moving your internet in Luxembourg: setting up your Eltrona box easily
Have you just moved to Luxembourg? Congratulations! The next chapter of your life can begin... provided your internet connection is ...
Have you subscribed to Luxembourg fibre, but your Wi-Fi still struggles to reach the upstairs bedrooms? You're not alone. In multi-storey homes packed with devices, smartphones, PCs, tablets and connected TVs, the basic network often shows its limitations. Fortunately, there are practical solutions to optimise your home Wi-Fi. Thanks to proven techniques and mesh technology, you can transform your connection into a smooth, stable and consistent network. Here's how.
Why conventional Wi-Fi struggles in multi-storey homes
Physical obstacles attenuate the signal.
- Thick walls, concrete floors, or metal beams significantly weaken the Wi-Fi signal between floors.
- The larger your house is or the more floors it has, the more the signal from a box placed on the ground floor will decrease before reaching the upper floors.
Too many devices are overloading the network.
- A modern home often contains dozens of devices connected simultaneously (smartphones, PCs, TVs, home automation devices, etc.).
- A single box, especially an older one, struggles to handle this heavy load, resulting in slowdowns, latency or partial outages.
Fibre speed wasted by Wi-Fi
Even with very fast Luxembourg fibre, the Wi-Fi built into the box can limit the actual speeds achieved, especially in remote areas.
Mesh Wi-Fi: the most effective solution for multi-storey homes
What is a Wi-Fi mesh network?
A mesh network is based on several access points: a main node connected to the router, then satellites installed in different locations around the home. These nodes communicate with each other to provide a consistent and stable signal throughout the home.
Why mesh outperforms a conventional repeater
| Solution | Single network (SSID) | Loss of flow | Manual network change | Uniform coverage |
|---|---|---|---|---|
| Repeater/amplifier | ❌ often secondary network | 📉 split flow | ⚠️ reconnection required | ❌ limited |
| Mesh network | ✅ Same network for the entire house | ✅ preserved throughput | ✅ automatic change | ✅ seamless coverage everywhere |
The mesh prevents interruptions or delays when moving from one floor to another.
The tangible benefits for a multi-device household
- Smooth connection for remote working, 4K streaming, online gaming, video conferencing, even with multiple devices active at the same time.
- Nodes can be easily installed on each floor to ensure coverage.
- Flexibility and scalability: add an extra node if you extend your home or move devices.
How to deploy an effective Wi-Fi mesh network in your home
1. Choose the right equipment (Wi-Fi 6 / Wi-Fi 7 recommended)
- Opt for a Wi-Fi 6 or Wi-Fi 7 compatible mesh kit: these standards better manage a large number of devices and offer higher speeds.
- Ensure that the kit includes several units (at least 2 to 3) if your house has several floors.
2. Position the knots correctly
- Place the main terminal (connected to the fibre box) in a central, unobstructed and elevated location. This maximises the initial signal distribution.
- Install satellite terminals strategically: near areas known to have poor Wi-Fi reception (upstairs bedrooms, living room, office).
3. Disable the box’s Wi-Fi & create a single network
Once the mesh is installed, disable the box’s native Wi-Fi. Assign the mesh network the same name (SSID) and password for a seamless transition for all devices.
4. Maintain and update
- Regularly check for firmware updates: this improves stability and security.
- Perform speed tests after installation to validate network coverage and proper functioning.
5. For very thick walls or large areas: combine mesh + wired connection (Ethernet or PLC)
When walls are particularly thick, a wired (Ethernet) or PLC backhaul between nodes ensures an even more reliable and stable signal.
Comparison of the leading Wi-Fi solutions for multi-storey homes
| Solution | Suitable if… | Benefits | Limits |
|---|---|---|---|
| Wi-Fi from the box alone | Small dwelling, few appliances | Simple installation | Poor coverage upstairs, unstable connection |
| Wi-Fi repeater | Low to medium surface area, occasional need | Low cost, easy to set up | New network, split bandwidth, limited coverage Selectra+1 |
| Mesh Wi-Fi network | Multi-storey house, many appliances, stability requirements | Uniform coverage, single network, consistent throughput, scalable | Higher cost, requires multiple nodes, more involved initial setup |
👉 For a connected home (fibre + 4K TV, remote working, home automation, etc.), Wi-Fi mesh is clearly the most suitable solution.
Why choose Eltrona’s services?
- Eltrona already offers a very high-speed fibre package: switching to mesh allows this fibre to be used to its full potential.
- Using Eltrona’s Wi-Fi diagnostics, a technician studies signal propagation, determines the ideal number of nodes and optimises their placement.
- This eliminates dead zones, ensures a stable connection, and prevents dissatisfaction caused by poor Wi-Fi.
In summary…
If your multi-storey home has numerous connected devices and you are experiencing signal loss, dead zones or slow speeds, it is time to take action. A properly installed Wi-Fi mesh system transforms a chaotic network into a smooth, uniform and reliable one. Combined with Eltrona’s personalised diagnosis, it guarantees a high-performance home network, today and tomorrow.

Frequently Asked Questions
Pourquoi ma fibre Luxembourg ne suffit-elle pas à garantir un bon Wi-Fi à l’étage ?
La fibre gère le transit des données jusqu’à la box, mais la couverture Wi-Fi dépend de la box et des obstacles physiques (murs, planchers). Ce sont ces éléments qui limitent le signal.
Un répéteur Wi-Fi ne suffit-il pas pour améliorer la couverture ?
Un répéteur peut aider ponctuellement, mais il divise souvent le débit, crée un second réseau, et offre une couverture limitée, loin d’un maillage homogène.
Combien de nœuds mesh faut-il pour une maison à 2–3 étages ?
Généralement 2 à 3 nœuds : un principal relié à la box et un ou deux satellites placés à chaque étage, à ajuster selon la surface et la structure.
Le Wi-Fi mesh convient-il aussi si j’ai des appareils filaires (PC, console, TV) ?
Oui. Beaucoup de kits mesh offrent des ports Ethernet sur les nœuds : pratique pour relier directement certains appareils à haut débit.
Faut-il que l’installation soit complexe pour passer au mesh ?
Non. La plupart des kits mesh sont « plug-and-play ». Au besoin, vous pouvez recourir à un diagnostic et un accompagnement, par exemple via Eltrona.
