eir slow internet in Ireland: tests, evidence and complaints

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

Applies to: eir fibre box 7 and eir fibre box F3000 (Sagemcom F5366s), menus as of 2026. eir’s tutorials cover the fibre box 7; the deeper settings come from eir’s F3000 user manual, so labels on the fibre box 7 may differ slightly. The older F2000 and F1000 have different menus.Checked: 3 November 2026

When this helps

  • You use eir in Ireland.
  • Your connection is slower than expected, drops out or performs badly at certain times.

Check your eir fibre box

These checks apply to eir fibre box. Check the model before following its menus.

  1. Check the lights; on the fibre box 7 the power and internet (@) lights sit on the front.

  2. Sign in and click Internet Connectivity › Basic for the public IP address and DNS servers.

  3. Click Modem Config › Device Info › Statistics for LAN, WAN and Ethernet counters.

  4. Click Modem Config › Maintenance › Logs for the event log, and Internet Utilities for ping and DNS tests.

Separate the service from your home Wi-Fi

For the exact settings and supported equipment, see the eir fibre box 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 eir

Use eir’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 Ireland service contract before escalating. Use the national regulator’s consumer guidance for your service.

Your local escalation route

Ask the provider for its complaints code and a unique complaint reference. ComReg Consumer Care explains how it can help with unresolved complaints.
