# Deutsche Telekom slow internet in Germany: tests, evidence and complaints

If your Deutsche Telekom connection is slow or unreliable, start with these equipment checks. Then document a repeatable result and ask for a specific investigation.

Applies to: Speedport Smart 4 (Typ A) with firmware 010139.5.x (menus as of 2026), and the Smart 4 family with the same interface. The interface is in German; labels are given with an English gloss. Speedport 7: MeinMagenta app only. · Checked: 3 November 2026

## When this helps

- You use Deutsche Telekom in Germany.
- Your connection is slower than expected, drops out or performs badly at certain times.

## Check your Speedport

These checks apply to Speedport. Check the model before following its menus.

1. Sign in and click **Übersicht › Status** (Overview › Status) for the main status information.
2. Click **Internet › IP-Adressinformationen** for your public IPv4 and IPv6 addresses.
3. Click **System › System-Meldungen** (System messages) for the event log.
4. Tick **Ausführliche System-Meldungen erfassen** for more detail, and **Liste exportieren** to save it.

## Separate the service from your home Wi-Fi

For the exact settings and supported equipment, see [the Speedport guide](https://kilobat.app/routers/telekom-speedport).

Do not factory-reset the equipment as a first step. A reset can erase service settings and interrupt phone service.

1. Compare a wired connection to the router with Wi-Fi on the same device.
2. Repeat the same test server during the slowdown and at a quieter time.
3. Record download, upload, latency and whether another household device was using the connection.

## How to complain to Deutsche Telekom

Use [Deutsche Telekom’s official support](https://www.telekom.de/hilfe/geraete/router/speedport/konfigurationsmenue-oeffnen) to report the fault. Request a formal complaint reference if it remains unresolved.

Include the plan wording, dates, test conditions, previous references and the specific outcome you want. Ask for a written response.

For the local escalation route and conditions, follow [the Germany complaint guide](https://kilobat.app/guides/germany-slow-internet-speed-reduction).

## Official credit or compensation information

[Check Deutsche Telekom’s published claim or compensation route](https://www.telekom.de/kontakt). Review its current conditions for the fault you experienced.

A total loss of service, intermittent faults and slow speeds can follow different rules. A report does not establish eligibility by itself.

## Collect the evidence with Kilobat

On a Mac, Kilobat can record connection checks and produce a support report. Review the report and add your test conditions before sharing.

The basic report export is free. [Kilobat Pro’s complaint wizard](https://kilobat.app/internet-complaint) helps assemble your evidence, impact and requested resolution into a draft you review and send.

Measurements cover this Mac while monitoring ran. They cannot prove whole-home uptime, establish provider fault or replace a required official measurement procedure.
