Quick answer

Your Roku detects that the internet connection is too slow. Move the Roku player closer to the router and restart the modem and router; if other devices are also slow or offline, contact your internet provider.

Safety first

Stop and check this first

  • If router settings need changing, ask the provider to do it or follow their guidance; a wrong change can leave the rest of the home offline.

Safe checks you can perform

  • Internet on another device on the same network
  • Move the Roku closer to the router
  • Restart modem and router

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Home network or Wi-Fi installer
  • Do not attempt this professional task: Internet provider

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Internet on another device on the same network

    No special tools

    Who:
    you.
    How:
    connect a phone, tablet or laptop to the same Wi-Fi network and open a website.
    Result that matters:
    whether that other device can browse.
    If it cannot browse either:
    points to a network or line problem; Roku refers you to your internet provider.
    If it browses:
    rules out a general outage; continue with the Roku device.
    Evidence to keep:
    a screenshot of the other device browsing or failing.

    Evidence: Why won't my Roku streaming device connect to Wi-Fi?

  2. Move the Roku closer to the router

    No special tools

    Who:
    you.
    How:
    move the Roku player closer to the router and connect again.
    Result that matters:
    whether 018 clears with the Roku closer.
    If it clears:
    confirms the Wi-Fi link was slow.
    If it remains:
    rules out distance; restart modem and router.
    Evidence to keep:
    the position tried and the result.

    Evidence: Why won't my Roku streaming device connect to Wi-Fi?

  3. Restart modem and router

    No special tools

    Who:
    you.
    How:
    unplug the modem and router (or gateway) for 10 seconds, plug them back in and wait for them to restart; if they do not, ask your provider or the device maker.
    Result that matters:
    whether the Roku stops showing 018.
    If it is fixed:
    indicates the router was overloaded or stuck.
    If every device stays slow:
    confirms a line problem; call the provider.
    Evidence to keep:
    the restart time and the light status.

Where this code applies

A code is meaningful only inside the right product and version context.

Roku

Known code variants

  • código de error 018 Roku
  • Error 018
  • Roku error 018
  • Roku error code 018
  • Roku slow internet

What it means

Roku assigns code 018 to slow internet in its connection error table, and recommends moving the Roku player closer to the router and restarting the modem and router. The slowness can come from the Wi-Fi link between router and Roku or from the provider line; tests with another device on the same network separate the two. The code does not point to any part of the TV or player.

Warnings and stop conditions

  • Loweditorial warning

    If router settings need changing, ask the provider to do it or follow their guidance; a wrong change can leave the rest of the home offline.
