Quick answer

2124-8028 is a Nintendo Account sign-in error, for example when starting Nintendo eShop, that Nintendo says is likely caused by a weak wireless signal or slow internet. Move the console nearer the router and power cycle the network.

Safety first

Safe checks you can perform

  • Bring the console closer and remove interference
  • Power cycle your home network
  • Try the other wireless band

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Your internet provider
  • Do not attempt this professional task: Whoever manages the router

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Your internet provider

    What they doWhen the code continues after the network steps and after waiting, the provider checks whether the line has a temporary fault or a speed problem, which is the case Nintendo describes.

    They must show youa speed or line test from their side at the time the console fails.

    In writingwhat they found on the line and what they changed, with the date.

  2. Whoever manages the router

    What they doIf you cannot see the router settings, the person who manages it can tell you which network name is 2.4GHz and which is 5GHz, so you can try the other band as Nintendo suggests.

    They must show youthe two bands and their network names in the router settings.

    In writingwhich band the console should use and any setting they changed.

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. Bring the console closer and remove interference

    No special tools

    Who:
    you.
    How:
    place the console within 3 to 5 metres of the wireless router while you troubleshoot, ideally out of the dock. Move filing cabinets, speakers, power strips, glass or cordless phones away from the console and the router.
    Result that matters:
    whether the connection works with a stronger signal.
    If it works:
    weak signal or interference was the cause; keep the console in a better position or move the obstacles for good.
    If the code returns:
    try the other wireless band if your router has one.
    Evidence to keep:
    where the console was and what you moved.

  2. Power cycle your home network

    No special tools

    Who:
    you, or whoever manages the router.
    How:
    unplug the power cable from the modem and from the wireless router if it is separate. If the modem lights stay on, it may have a backup battery that must be removed. After 30 seconds, plug the modem back in and wait for its lights to stay steady, then plug in the router and wait for its lights to stay steady.
    Result that matters:
    whether the console connects without the code once both devices are back.
    If it connects:
    an unresponsive network device was the cause.
    If the code returns:
    go on to the next check.
    Evidence to keep:
    time of the power cycle and the result.

  3. Try the other wireless band

    No special tools

    Who:
    you.
    How:
    if your router supports both 2.4GHz and 5GHz, set up a connection to the band you are not using now. The default network names often show which is which; otherwise the router's settings show it.
    Result that matters:
    whether the code stops on the other band.
    If it stops:
    the band you were using was the problem; stay on the new one.
    If it continues:
    the issue is not the band.
    Evidence to keep:
    which band and network name you tested.

What it means

Nintendo documents 2124-8028 on Nintendo Switch 2 and Nintendo Switch when signing in to a Nintendo Account fails, for example when starting Nintendo eShop. Although the code belongs to Nintendo Accounts, Nintendo says it is likely due to a poor network environment, such as weak wireless strength or slow internet speeds. The steps target the connection: console within 3 to 5 metres of the router, out of the dock while testing, power cycle the home network, move interfering objects and try the other wireless band. If it persists, it may be a temporary issue with your internet service.

Symptoms and causes

Probable causes · in order

  • Weak wireless signalCommon

    Evidence: Nintendo Switch error code 2124-8028 (Nintendo UK Support)

  • Slow internet speedPossible

    Nintendo also names slow internet speeds. The sign-in times out even though the account itself is fine.
