By How to test your Internet speed properly
Testing your internet speed is quick and easy, but doing it properly is what gives you useful, reliable results. Follow these simple steps before you hit Start:
Use one device only
Pause all downloads, streams, cloud backups and updates.
Restart your modem/router
If it has been on for weeks without a break.
Sit close to your WiFi router
Or, even better, plug in with an Ethernet cable.
Close unnecessary apps and tabs
Make sure your browser is up to date.
Run the test 2–3 times
Note the average download, upload and ping.
For better results, compare a WiFi speed test with a wired broadband speed test. If wired is much faster, your ISP is fine, your WiFi setup is the issue.
Understanding your Internet speed test results
A speed test gives you a number; what matters is whether that number is normal. Find your download result in the table below to get the verdict straight away, then read on for what each metric actually measures.
| Your download result | What it means | What to do next |
|---|---|---|
| Below 20 Mbit/s | You are on an ADSL line, or your fibre connection has a fault. | Check whether fibre is available at your address. |
| 20 to 100 Mbit/s | Normal for VDSL copper, but low for a fibre plan. | Re-test with an Ethernet cable before blaming your provider. |
| 100 to 300 Mbit/s | Fibre is working, but you are below the French average. | Your WiFi or your plan tier is the limit, not the network. |
| 300 to 600 Mbit/s | In line with what fibre actually delivers in France. | Nothing to fix. |
| Above 600 Mbit/s | Faster than the average French fibre connection. | Nothing to fix. |
Each number tells you something different about how smooth your online life will be. Download speed drives streaming and browsing, upload speed powers video calls and file sharing, while ping and jitter decide how "laggy" everything feels in real time.
Fibre broadband delivers far higher and more stable speeds than ADSL, especially when several people are online at once. The figures below are what the four main French providers were actually measured at, not what their adverts promise.
| Metric | What it tells you | Fibre (FTTH) | ADSL / VDSL copper |
|---|---|---|---|
| Download speed | How fast you receive data (streaming, browsing, downloads) | 570 Mbit/s measured on average on FTTH lines; plans advertise 1 to 8 Gbit/s, which is the theoretical maximum of the technology | 11 Mbit/s on ADSL, up to 100 Mbit/s on VDSL |
| Upload speed | How fast you send data (video calls, file uploads, cloud backups) | 267 to 371 Mbit/s measured per operator, all fixed technologies combined | 0.5 to 1 Mbit/s |
| Ping / latency | How long data takes to travel back and forth, crucial for gaming and video calls | 12 to 16 ms measured | 40 to 80 ms |
| Jitter | How much your ping varies over time; high jitter causes choppy sound and video | Target below 20 ms | 30 to 40 ms |
Two different perimeters, so read them separately. The 570 Mbit/s FTTH average covers fibre lines only (ARCEP and market data on fixed access technologies). The per-operator figures (340 to 491 Mbit/s download) come from the nPerf 2025 fixed-line barometer and average all of an operator's fixed customers — fibre, VDSL and cable together — which is why they sit below the fibre-only average. Advertised tiers verified against the live offer catalogue — last checked September 2026.
What is a good Internet speed in France in 2026?
Fibre plans are sold from 1 to 8 Gbit/s. Those figures are the theoretical maximum of the technology, and no connection reaches them in a real home — French FTTH lines average about 570 Mbit/s in practice, which is normal and expected. What the tier really buys you is headroom: how much speed survives WiFi, simultaneous devices and peak hours.
How much Internet speed do you actually need?
These are the minimums published by the platforms themselves. They tell you the floor your connection must clear — not the plan you should buy, because measured throughput is a fraction of the advertised figure.
| Activity | Download needed | Upload needed | What actually matters |
|---|---|---|---|
| Email, browsing, social media | 1 to 5 Mbit/s | Under 1 Mbit/s | Any connection copes. |
| Music streaming | 2 Mbit/s | — | Stability, not speed. |
| HD video streaming, one screen | 5 Mbit/s | — | Netflix's published HD minimum. |
| 4K video streaming, one screen | 15 to 25 Mbit/s | — | Multiply by the number of screens. |
| Video calls in 1080p | 3 Mbit/s | 3 Mbit/s | Upload matters as much as download. |
| Online gaming | 5 to 10 Mbit/s | 1 to 3 Mbit/s | A ping below 50 ms beats raw speed. |
| Cloud gaming in 1080p60 | 15 to 25 Mbit/s | — | Around 35 Mbit/s for 4K. |
| Large uploads and cloud backup | — | 10 Mbit/s and up | Where fibre beats copper hardest. |
Figures are the minimum requirements published by the streaming, calling and cloud-gaming platforms themselves — last checked September 2026.
Add up everything running at once and a busy household easily reaches 60 to 150 Mbit/s of sustained demand. That looks small next to a 1 Gbit/s plan until you remember that an FTTH line delivers around 570 Mbit/s in practice, that WiFi takes another 7 to 29% on top, and that every device shares the same line. Headroom is not vanity: it is what absorbs those losses at 9pm with four screens running.
Which fibre speed tier to choose
Fibre in France is sold in three tiers, and the entry tier already starts at 1 Gbit/s — nothing slower is on the market. So the choice is not whether your streaming will work, it is how much headroom, upload and WiFi equipment you want:
Single person or couple, student, streaming HD, browsing, a few video calls. This is the market floor — nothing slower is sold on fibre any more.
Power users (home office with big file transfers, multiple gamers, many connected devices). This tier also carries the best WiFi equipment — WiFi 7 boxes and bundled repeaters — which is often what makes the difference you actually feel.
If your speed test shows much less than what your fibre plan advertises, or you are stuck on ADSL below 30 Mbps, it's a clear signal it's time to upgrade your offer or switch Internet provider in France.
Why your broadband speed test is slower than expected
A broadband speed test that looks slow doesn't always mean your provider is scamming you. In most cases, something in your home setup or on the network is quietly eating away at your bandwidth — and the single biggest culprit is the WiFi between your box and your device.
WiFi speed test vs wired speed test
If you run a WiFi speed test, you are measuring your WiFi, not your fibre line. The gap is measurable and it varies enormously by provider: across France in 2025, download speeds over WiFi came out 7% lower than over cable at Bouygues Telecom, but 29% lower at Free. Free posts some of the highest wired speeds in the country and still slips to third place over WiFi, because the bottleneck is the box's WiFi, not the network.
| Provider | Wired download | WiFi download | Speed lost on WiFi |
|---|---|---|---|
| Bouygues Telecom | 491 Mbit/s | 456 Mbit/s | 7% |
| Orange | 425 Mbit/s | 380 Mbit/s | 11% |
| Free | 451 Mbit/s | 321 Mbit/s | 29% |
| SFR | 340 Mbit/s | 303 Mbit/s | 11% |
Wired and WiFi download speeds measured by the nPerf 2025 fixed-line barometer for France (2025 data, published January 2026). Both columns average all of an operator's fixed customers, so what matters here is the gap between the two, not the absolute figures.
The practical takeaway: always run one test over WiFi and one with an Ethernet cable. If the wired result matches your plan, your line is fine and the fix is your WiFi setup, not your provider.
What else slows your connection down
Beyond the WiFi-versus-cable gap itself, the usual culprits are:
Outdated or overloaded equipment
Old routers, weak WiFi, bad Ethernet cables or boxes that haven't been restarted for weeks.
Too many devices at the same time
Streaming, gaming, video calls and smart home devices all competing on the same connection.
WiFi placement and interference
Distance from the box, thick walls, interference from neighbours' networks or staying stuck on a crowded 2.4 GHz band.
Network congestion or throttling
Speeds dropping at peak hours because everyone is online, or temporary slowdowns applied to heavy users.
Access technology and line quality
ADSL lines far from the exchange, or mixed fibre/copper (FTTC) links, will never match full FTTH performance.
How to Improve a slow Internet connection
Quick fixes you can try now to boost your Internet speed
Before you change provider, try a few quick wins that often boost a slow connection in minutes.
Restart your modem/router
Unplug it for 30 seconds, then plug back in to clear glitches and refresh the signal.
Move your router
Central, elevated, open spot — not in a cupboard, not on the floor, away from microwaves or thick walls.
Disconnect unused devices
Old phones, smart TVs, consoles stop silently consuming bandwidth in the background.
Use an Ethernet cable
For your main PC, TV or console to get a faster and more stable connection than WiFi.
Switch to 5 GHz WiFi
For nearby devices to gain speed and reduce interference; keep 2.4 GHz for rooms further away.
When to upgrade your broadband plan or switch providers in France
If your internet still crawls after basic WiFi fixes, it's probably not you: it's your plan or provider. In fibre-covered France, where 94.9% of premises can now get FTTH (42.8 million out of 45.1 million, ARCEP figures for the first quarter of 2026), staying on an old or underpowered offer makes less and less sense.
You should seriously consider upgrading or cancelling your current broadband plan, or even switching provider when:
Your speed test regularly shows much lower speeds than those advertised in your contract, even on a wired connection and outside peak hours.
Streaming, video calls or cloud tools freeze as soon as several people are online, a clear sign your bandwidth no longer matches your household's usage.
You are still on ADSL or VDSL in an area where fibre is available on your line, which now covers the vast majority of homes in France.
Your provider cannot offer higher speeds, better WiFi equipment or a more recent Internet box without extra fees that are out of line with the market.
In all these cases, checking current fibre deals and potentially switching providers in France is often the fastest way to actually feel a before/after difference.
Switching does not have to cost you the cancellation fees: Orange refunds up to €150, while SFR, Free and Bouygues Telecom refund up to €100. You will normally need proof of cancellation, the itemised fee invoice, and to sign up to an eligible plan within a set deadline.
Which provider offers the fastest Internet speeds?
According to the nPerf 2025 barometer of fixed connections in France (2025 data published on 12 January 2026), Bouygues Telecom confirms its position as market leader, with the best overall score and a particularly consistent user experience, supported by very high speeds, low latency, and excellent performance in both browsing and streaming.
Orange secures a strong second place, driven by high average speeds and very reliable overall service quality across all fixed uses. Free remains a very aggressive competitor, especially on downstream and upstream speeds, but its overall score is still slightly behind Bouygues Telecom and Orange, which indicates a user experience that is somewhat less polished according to nPerf.
SFR, finally, comes last with more modest performance, particularly in terms of speeds and latency, even though the operator also benefits from the overall improvement trend of fixed connections in 2025.

Internet speed test: frequently asked questions
How do I check my internet speed? Read more Close
Use the speed test at the top of this page: it measures your download, upload and ping in about 30 seconds, with no account needed. For a reliable result, pause other downloads and streams, use one device, and run the test two or three times to take an average.
What is a good internet speed in France? Read more Close
French FTTH lines average about 570 Mbit/s download in real conditions, while plans are sold from 1 to 8 Gbit/s — those headline figures are theoretical maximums. Anything above 300 Mbit/s is comfortable for a busy household; on ADSL, a typical line delivers around 11 Mbit/s.
Why is my WiFi speed test slower than my wired test? Read more Close
Because a WiFi test measures your WiFi, not your fibre line. Measured across France in 2025, WiFi cost 7% of download speed at Bouygues Telecom and 29% at Free. Distance from the box, thick walls, neighbouring networks and staying on the 2.4 GHz band all widen that gap.
How much internet speed do I actually need? Read more Close
Far less than most plans advertise. HD streaming needs 5 Mbit/s, 4K needs 15 to 25 Mbit/s per screen, and a 1080p video call needs 3 Mbit/s each way. A couple streaming 4K on two screens while someone works from home needs roughly 60 Mbit/s in total.
Why does my internet speed drop in the evening? Read more Close
Evening slowdowns usually come from network congestion: everyone in your area is online at once. They are much more noticeable on ADSL and cable than on fibre. Test at two different times of day to tell congestion apart from a genuine fault on your line.
What is a good ping for gaming? Read more Close
Aim for a ping below 50 ms, and keep jitter under 20 ms so the delay stays steady. French fibre measures 12 to 16 ms, against 40 to 80 ms on ADSL — which is why fibre transforms online gaming far more than the raw download figure suggests.
