Optimise your home Wi-Fi: 7 effective solutions without changing your router

1. Diagnose the network before taking action

Map your dead zones

• Use a free app (e.g., Wi-Fi Analyzer) to view the signal strength room by room.
• Note the descending and ascending speeds at different times of the day.

Measure channel saturation

Channels 1, 6, and 11 in the 2.4 GHz band are often congested in buildings. Switching to a less congested channel can double the perceived speed.

2. Position and configure the box intelligently

1. Height & centrality: place the modem 1.2 metres above the floor, away from load-bearing walls and metal devices.
2. Up-to-date firmware: recent firmware fixes security vulnerabilities and optimises the antenna algorithm.
3. 5 GHz band for speed, 2.4 GHz for range: activate both SSIDs so that each device connects to the best compromise.

Quick setup tip: Enable the Quality of Service (QoS) feature to prioritise video calls or gaming during peak hours.

3. Utilise repeaters and smart powerline communication

Eltrona’s internal guide recommends one or two repeaters for dwellings with fewer than two floors, and more for larger houses.

FRITZ!Repeater or hybrid powerline Wi-Fi models create a local access point without significant bandwidth loss.

4. Switch to Wi-Fi mesh: the all-round solution

A mesh system deploys multiple nodes that coordinate under a single SSID. Tests show:

Advantage	Tangible impact
Seamless roaming	No interruptions during video calls while on the move
Automatic load balancing	Constant flow rate even for 20 devices
Modular installation	Adding a node ≈ 5 min via app

According to Lifewire, a mesh network is particularly suitable for homes larger than 200 m². The global mesh market is expected to grow by 15% per year until 2033, demonstrating rapid adoption by multi-device households.

5. Optimise advanced settings

Separate guest SSID

Limit bandwidth for guests and isolate your sensitive IoT devices.

Enable band steering

The box automatically directs each device to the least congested band.

Schedule Wi-Fi monitoring

Switch off the signal at night to save energy — a feature built into the GIGA Eltrona Internet box.

• WPA3: the most robust encryption.
• Unique password of at least 12 characters.
• Monthly analysis via the box app: detects unknown devices.

7. Take advantage of Eltrona’s Wi-Fi diagnosis

Eltrona technicians carry out a propagation study, recommend the ideal number of mesh nodes and optimise your settings. Included in the GIGA Internet offer for all 1 Gbit/s fibre subscriptions, this service reduces churn caused by poor coverage.
