Internet slower than promised in Finland: your rights

The short answer

Your contract must state the speed: for fixed broadband a minimum, normal and maximum speed, for mobile broadband an estimated maximum speed, plus the advertised speed. If there is a data cap, it must say how reaching it affects speed.

Your contract states the speeds your provider promises. If the real speed falls clearly and repeatedly below them, you may be able to pay less or end the contract. A measurement with the official tool, where there is one, is the strongest proof.

📜 The rules in Finland

What you can do

Complain to the operator quickly and demand a fix. If it is not fixed, you can demand a price reduction; if the promised speeds cannot be delivered, you can cancel the contract, even a fixed-term one. Small temporary variations may not entitle you to compensation.

The details

Traficom's position: for fixed broadband up to 100 Mbit/s, the stated minimum must be at least 70% of the maximum, and the maximum must be reachable at least some of the time. It recommends a normal speed of 90% of the maximum. (traficom.fi)
For proof, use the free Bittimittari.fi quality survey: four hours of automatic measurements over an Ethernet cable, for fixed connections up to 100/100 Mbit/s. To complain, run two surveys on different days and keep both reports. (bittimittari.fi)
Mobile broadband speeds are usually given as wide ranges, so a slow connection is not automatically a fault. It can be one if a higher speed was promised in marketing or when you signed; oral promises are hard to prove. (kkv.fi)
If the operator restricts traffic against the EU Open Internet Regulation, or your contract lacks the required information, contact the operator first and then Traficom. (traficom.fi)

❓ Questions

Does a quick speed test in an app count?

It helps you spot a problem. As proof, a measurement made the way the regulator or your contract describes carries much more weight.

Does this apply to mobile internet too?

Mobile speeds change with place and network load, and the rules for mobile are often different. See the rules for Finland on this page.

Is slow Wi‑Fi the provider’s fault?

Not always. Walls, distance and old devices slow Wi‑Fi down. Measure with a cable first.
