Why Test Your Freebox Speed?
Free Telecom (Iliad group) is one of France's four major operators, known for its competitively priced Freebox plans. The Freebox Delta, Freebox Ultra, Freebox Pop and older Freebox Revolution all offer different speed capabilities — and your actual performance depends on your technology (ADSL, VDSL2 or FTTH fiber), line quality and home network setup.
A test de vitesse Free with SpeedTrest gives you unbiased, real-time measurements that are independent of Free's own infrastructure. Free fiber subscribers on the Freebox Ultra should see multi-gigabit download speeds; on standard ADSL, speeds depend heavily on your distance from the telephone exchange.
- Verify Free is delivering the speeds promised in your Freebox contract
- Identify if your Freebox router or WiFi is the bottleneck
- Build documentation before contacting Free support (3244)
- Compare speeds at different times to detect congestion patterns
Freebox Speed Plans — What to Expect
| Freebox Plan | Technology | Typical Download | Typical Upload |
|---|---|---|---|
| Freebox Ultra | FTTH | 8 Gbps | 8 Gbps |
| Freebox Delta / Pop (Fiber) | FTTH | 500–1000 Mbps | 500–700 Mbps |
| Freebox Revolution (Fiber) | FTTH | 500–1000 Mbps | 200–400 Mbps |
| Freebox VDSL2 | VDSL2 | 20–100 Mbps | 5–20 Mbps |
| Freebox ADSL | ADSL2+ | 1–20 Mbps | 0.5–2 Mbps |
Free is one of the few operators offering symmetric multi-gigabit speeds on the Freebox Ultra. If you're on this plan, test via 10 Gbps Ethernet for accurate results — standard Gigabit Ethernet ports will cap your measurement at ~940 Mbps.

Run Speed Test →Why Your Freebox Speed May Be Lower Than Expected
Ethernet port limitation: If your Freebox is the Ultra (8 Gbps) but your device only has a standard 1 Gbps Ethernet port, your speed test will cap at ~940 Mbps regardless of your plan. You need a 10 Gbps NIC to fully test the Ultra plan.
WiFi interference: Free Freebox routers support WiFi 6 (and WiFi 7 on the Ultra), but neighbouring networks, walls and electronic devices still reduce wireless speeds. Test via Ethernet first to establish a baseline.
Distance from the DSLAM (ADSL/VDSL): On copper lines, the farther you are from the telephone cabinet, the lower your ADSL or VDSL2 speeds. Free cannot improve the physical copper infrastructure — fiber migration is the only real solution.
Freebox firmware: Free pushes updates automatically. Access the Freebox admin panel at 192.168.0.254 to verify your firmware version and check for pending updates.
Evening congestion: Free's network, like all French operators, sees peak traffic between 7 and 11 PM. ADSL and VDSL2 are most affected; fiber is generally more resilient.
How to Optimize Your Freebox Speed
1. Use Ethernet for accurate testing
Plug directly into the Freebox with an Ethernet cable. This eliminates WiFi as a variable and gives you the true line speed from Free's infrastructure.
2. Restart the Freebox
Use the Freebox admin panel at 192.168.0.254 or press the power button on the device for 5 seconds. A fresh connection often resolves temporary slowdowns.
3. Enable 5 GHz or 6 GHz WiFi
All recent Freebox models support 5 GHz WiFi. The Freebox Ultra also supports 6 GHz (WiFi 7). Connect to the faster band — look for the 5G or 6G suffix in your WiFi network name.
4. Place the Freebox Server centrally
The Freebox system separates the modem (Freebox Server) from the WiFi router (Freebox Player or Mini 4K). Ensure the Freebox Server has a clear path to the main devices you use.
5. Check fiber eligibility
If you're on ADSL, visit free.fr to check if fiber is available at your address. Free's FTTH rollout is extensive across France and significantly outperforms copper in both speed and reliability.
Frequently Asked Questions
What speed should I get with a Freebox fiber plan?
On Freebox Pop or Delta fiber (1 Gbps plan), expect 700–940 Mbps download via Ethernet. On the Freebox Ultra (8 Gbps), you need a 10 Gbps network card to measure full speeds — standard Gigabit Ethernet caps at ~940 Mbps.
How do I contact Free if my speed is consistently low?
Call Free support at 3244 (Mon–Fri 8 AM–10 PM, weekends 9 AM–8 PM) or use the Freebox Console app (console.free.fr). Always run a SpeedTrest test beforehand and note your results, connection type and Freebox model.
Why does my Freebox ADSL speed vary so much?
ADSL speeds fluctuate with line quality, temperature and traffic load. Distance from the exchange is the main factor — the further you are, the lower your maximum speed. Free can run a remote line diagnostic from their end if you report consistent issues.
