Is your Wi-Fi slow? 5 checks to do at home

1. Check the location of your router

A router tucked away behind a shelf or in a dark corner will not work miracles. Thick walls, metal and even mirrors can block the waves.

Best practices:

• Place the router in the centre of the room.
• Avoid placing it on the floor or in a closed cabinet.
• Raise it up (for example, onto a shelf).

👉 On average, a poor location can reduce performance by 30 per cent (source: IEEE Communications Survey, 2023).

2. Analyse the number of connected devices

A typical family in Luxembourg uses between 10 and 15 connected devices (smartphones, TVs, computers, consoles, connected objects). Each device uses bandwidth.

• Disconnect unused appliances.
• Limit large downloads during peak hours.
• Enable parental controls to manage usage.

An Internet subscription tailored to your needs can also make a difference. At Eltrona, various packages allow you to adjust the speed and stability according to your usage.

3. Switch to Wi-Fi Mesh if your home is large

If your house or flat is larger than 100 m², a single router may not be sufficient. Wi-Fi Mesh allows you to create a seamless network using several interconnected access points.

Advantages of Wi-Fi Mesh:

• Uniform coverage in all rooms.
• Fewer dead zones (remote rooms, attic, garage).
• Automatic switching to the most efficient access point.

According to an IDC study (2024), 42% of European households equipped with Wi-Fi Mesh see an immediate improvement in performance.

4. Check the quality of your Internet connection

Slow Wi-Fi is not always caused by the internal network: the source may be the connection itself. With coaxial fibre, Eltrona offers stable and consistent speeds, ideal for households with multiple devices.

How to test your connection:

• Use a speed test (such as nPerf or Speedtest).
• Compare the results with the speed of your subscription.
• If the discrepancy is significant, restart the modem before contacting support.

5. Update your equipment

An outdated router may limit performance. The current Wi-Fi 6 standard handles congestion better and offers higher speeds.

Technical checklist:

• Check the date of purchase of your box/router.
• Enable automatic software updates.
• Consider replacing your equipment every 4–5 years.

Before calling support, there are a few simple steps you can take to improve your connection. By optimising the placement of your router, managing the number of devices, investing in a Wi-Fi mesh system or choosing coaxial fibre, you can enjoy greater comfort and stability.
