# What if internet speed is below the minimum?

> Use the contract’s measurement conditions and recorded evidence before requesting a speed-related remedy.

A low result needs an explanation of the test conditions and the promise being assessed.

## Which minimum-speed promise applies?

Use the current terms for the actual product and the specified measurement procedure.

An advertised maximum, a public average and a contractual minimum describe different things. The older Wiseuser comparison table is dated 2020 and is not reproduced as a current set of thresholds.

## Which details should be recorded with a test?

Keep the time, product, test method, connection and provider fault-reference record.

Ask which device and wired or wireless arrangement the provider requires for the contractual test. Preserve results and the technical response without publishing account or address details.

## How do outage criteria differ from low speed?

A service-outage duration rule and a contractual minimum-speed provision need separate evidence.

The checked consumer criteria, effective 18 December 2025, list penalty-free cancellation for outages of at least one hour occurring at least three times in a month, or cumulative monthly outages of at least 24 hours, subject to the stated timing and exclusion notes. These are outage criteria, not a rule that one slow speed test qualifies.

## What should be requested before ending the service?

Request the provider’s findings, applicable clause and proposed settlement in writing.

The bundle criteria also refer to termination grounds under contractual minimum-speed guarantees and distinguish mobile contracts. Retain the response and use an official consumer or telecommunications dispute route if the disagreement remains.
