Optimize home wi-fi: 7 effective solutions without changing your box

1. Diagnose your network before taking action

Map out dead zones

• Use a free app (e.g. Wi-Fi Analyzer) to check signal strength in each room.
• Record upload and download speeds at different times of the day.

Measure channel saturation

Channels 1, 6, and 11 on 2.4 GHz are often crowded in apartment buildings. Switching to a less congested channel can double your perceived speed.

2. Position and configure your box smartly

1. Height & centrality: Place the modem 1.2 m above the floor, away from thick walls and metal devices.
2. Up-to-date firmware: Updated software fixes security flaws and improves antenna performance.
3. 5 GHz for speed, 2.4 GHz for range: Enable both SSIDs so each device connects to the best option.

Quick tip: Activate Quality of Service (QoS) to prioritize video calls or gaming during peak hours.

3. Use repeaters and smart powerline adapters

Eltrona’s internal guide recommends one or two repeaters for homes under two floors, and more for larger houses.
FRITZ!Repeaters or hybrid Wi-Fi/powerline models create a local access point without significant bandwidth loss.

4. Switch to mesh wi-fi: the all-round solution

A mesh system deploys several nodes under one SSID, working together seamlessly. Tests show:

Advantage	Real-life impact
Seamless roaming	No call dropouts when moving around
Automatic load balancing	Stable speeds even with 20 devices
Modular installation	Add a node in about 5 minutes via app

According to Lifewire, mesh networks are especially suitable for homes larger than 200 m². The global mesh market is expected to grow by 15% annually until 2033, proving its rapid adoption in multi-device households.

5. Fine-tune advanced settings

Separate guest SSID

Limit bandwidth for guests and isolate sensitive IoT devices.

Enable band steering

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

Schedule wi-fi standby

Turn off the signal at night to save energy — built into Eltrona’s Internet GIGA box.

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

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

7. Take advantage of the Eltrona wi-fi diagnostic

Eltrona technicians perform a propagation study, recommend the ideal number of mesh nodes, and optimize your settings. Included with the Internet GIGA plan for all 1 Gbit/s fiber subscriptions, this service reduces churn caused by poor coverage.
