KPN Speed Test — Dutch Fiber Internet
KPN is the Netherlands' largest and oldest telecommunications company, the former state telecom monopoly that has transformed itself into the country's leading fibre provider. With over 3.5 million broadband customers, KPN serves roughly half of all Dutch internet subscribers — competing against Ziggo (cable) and a growing number of smaller fibre providers.
The Dutch broadband market is unique in Europe: extremely well-connected (99% of households have access to at least 100 Mbps), fiercely competitive, and backed by strong consumer protection laws including Vrije Modemkeuze (the legal right to use your own router). Whether you are on KPN Glasvezel or still on a copper DSL connection, this speed test will show you exactly what your line delivers.
KPN Plans — Glasvezel vs. Koper (Copper)
| Plan | Download | Upload | Technology | Price (€/mo) |
|---|---|---|---|---|
| Internet 100 | 100 Mbps | 100 Mbps | Glasvezel (Fiber) | ~€40 |
| SuperFiber 1 | 1 Gbps | 1 Gbps | Glasvezel (GPON) | ~€55 |
| SuperFiber 4 | 4 Gbps | 4 Gbps | Glasvezel (XGS-PON) | ~€65 |
| DSL (Koper) | 20-100 Mbps | 5-30 Mbps | VDSL2/Vectoring | ~€35-45 |
All KPN Glasvezel (fibre) plans are symmetrical — upload equals download. This is a significant advantage over Ziggo's cable network, where upload is typically limited to 50 Mbps regardless of the download tier. For households that stream to Twitch, host video calls, or run cloud backups, KPN's upload advantage is substantial.
KPN Box 12 and Box 14 — Your Modem
KPN supplies its own modems, and they use a quirky default IP that catches people off guard:
| Feature | KPN Box 12 (Sagemcom) | KPN Box 14 (Arcadyan) |
|---|---|---|
| Admin URL | 192.168.2.254 (not the typical 192.168.1.1!) | |
| Username | Pre-filled or "admin" | |
| Password | Printed on the modem's back sticker | |
| Wi-Fi | Wi-Fi 5 (802.11ac) | Wi-Fi 6 (802.11ax) |
| 2.5G Port | No | Yes (1 port) |
| Best For | Plans up to 500 Mbps | SuperFiber 1 / SuperFiber 4 |
Why 192.168.2.254? KPN intentionally chose a non-standard gateway IP to avoid conflicts. Many customers connect additional routers or access points that default to 192.168.1.1 — KPN's different range prevents double-NAT headaches. Smart decision, but confusing if you are used to other routers.
Light Indicators
- Power — Solid green: Modem is powered and functioning normally.
- Internet — Solid green: Online and connected to KPN's network. Everything is working.
- Internet — Slow flashing green: Attempting to connect. If it persists beyond 10 minutes on Glasvezel, check the patch cable between the FTU (fiber wall box) and the modem's red WAN port.
- Internet — Fast flashing green: Obtaining an IP address. Usually resolves within 1-2 minutes.
- Power — Red: Critical hardware failure or bad firmware. Try factory reset (paperclip in the reset hole for 15 seconds). If still red after reboot (allow 15 minutes), the modem needs replacement — call KPN.
- Wi-Fi — Off: Wi-Fi has been disabled in settings (intentionally or via button). Log into 192.168.2.254 to re-enable.
Vrije Modemkeuze — Using Your Own Router
The Netherlands is one of few countries where your legal right to use any compatible modem is protected by law. You do not need KPN's permission. The most popular alternative is the AVM FRITZ!Box — specifically designed for the Dutch market.
Setting up a FRITZ!Box with KPN Glasvezel:
- Connect the FRITZ!Box to the FTU (Fiber Termination Unit) on your wall using the fiber patch cable. Use the SFP module for fibre-capable models (FRITZ!Box 5590 Fiber) or a mediaconverter for older models.
- Power on and access fritz.box (or 192.168.178.1) in your browser.
- In the setup wizard, select "KPN" as your provider — the FRITZ!Box pre-loads the correct VLAN, PPPoE, and IPTV settings.
- Enter your KPN account credentials (found in your KPN account or welcome email).
- The internet, iTV, and VoIP phone should all configure automatically within a few minutes.
Why bother? The FRITZ!Box offers dramatically better Wi-Fi performance, built-in mesh support, DECT phone integration, NAS functionality, and much more granular network controls than the KPN Box 12. For tech-savvy Dutch users, the FRITZ!Box 5590 Fiber is the gold standard.
KPN vs. Ziggo — The Dutch Broadband Decision
In most Dutch households, the real choice is between KPN (fibre/copper) and Ziggo (cable). Here is what actually matters:
| Factor | KPN Glasvezel | Ziggo Kabel |
|---|---|---|
| Max Download | 4 Gbps (SuperFiber 4) | 1 Gbps |
| Max Upload | 4 Gbps (symmetrical) | 50 Mbps |
| Latency | 3-8 ms | 10-25 ms |
| Peak Hours | No impact (dedicated fibre) | Can slow 20-30% (shared cable) |
| Own Router | Easy (FRITZ!Box) | Harder (need modem + router) |
| Coverage | ~80% of NL (fibre expanding) | ~95% of NL |
| TV | iTV (IPTV-based) | Ziggo Go (cable + streaming) |
If KPN Glasvezel is available at your address, it is the technically superior choice — symmetrical speeds, lower latency, and future-proof infrastructure. Ziggo's advantage is wider coverage (cable reaches nearly every Dutch home) and a strong TV package. If you primarily care about download speed for streaming and do not upload much, both will serve you well.
Dutch Broadband Alternatives
- Ziggo — The Netherlands' cable monopoly (owned by VodafoneZiggo). Fast downloads but limited uploads. Good TV bundle.
- Odido (formerly T-Mobile Thuis) — Resells KPN fibre at competitive prices. Same network, often cheaper.
- Delta — Regional fibre and cable provider in Zeeland and parts of South Holland.
- CAIW / Glaspoort — Regional fibre operators building independent networks in specific cities.
