# Elisa slow internet in Finland: tests, evidence and complaints

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

Applies to: Zyxel EX5501 and DX3300-T0 as supplied by Elisa, from Elisa’s device pages and the Zyxel AX/DX/EX/PX series user’s guide Elisa links for the EX5501 (firmware 5.15–5.17). Elisa’s firmware may hide some menus. Elisa also hands out TP-Link, Huawei and cable modems with other addresses; check the label. The web interface is in English. · Checked: 3 November 2026

## When this helps

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

## Check your Elisa modem (Zyxel)

These checks apply to Elisa modem (Zyxel). Check the model before following its menus.

1. Check the Internet light; blue on the DX3300 means connected, red means an internet fault.
2. Open **System Monitor › Log › System Log** for events such as connection drops.
3. On a DSL line, open **System Monitor › xDSL Statistics** for sync rates and errors.
4. Use **Maintenance › Diagnostic** for ping, traceroute and nslookup tests.

## Separate the service from your home Wi-Fi

For the exact settings and supported equipment, see [the Elisa modem (Zyxel) guide](https://kilobat.app/routers/elisa-modem).

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 Elisa

Use [Elisa’s official support](https://elisa.fi/asiakaspalvelu/laitteet/zyxel-ex5501/) 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.

Check the complaints procedure in your Finland service contract before escalating. Use the national regulator’s consumer guidance for your service.

## Your local escalation route

Complain to the operator about service quality first. Traficom’s guidance distinguishes regulatory concerns from consumer compensation disputes.

[Traficom internet-service guidance](https://traficom.fi/en/communications-networks/open-internet-or-net-neutrality) lists the conditions and application route.

## 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.
