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.

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 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.
