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.
Restart the console
- Who:
- you.
- How:
- hold the POWER Button for three seconds, select Power Options and then Restart. Test the connection after each change.
- Result that matters:
- whether the connection test passes after the restart.
- If it passes:
- it was a temporary console state.
- If it fails:
- restart your home network.
- Evidence to keep:
- time of the restart and the test result.

Power cycle your home network
- Who:
- you.
- How:
- turn your router and modem off and on again. Before testing the console, check that the network devices are back on and other devices can reach the internet.
- Result that matters:
- whether the console connects once the network is back.
- If it connects:
- the network devices were unresponsive.
- If it fails:
- go on to the next check.
- Evidence to keep:
- time of the restart and whether other devices had internet.

Check the wireless password exactly
- Who:
- you, with your network's password.
- How:
- review your network password and the security setting in the console's internet settings. Enter the password exactly, including capital letters and symbols.
- Result that matters:
- whether the console connects with the corrected password.
- If it connects:
- the password was wrong, the most common cause Nintendo gives.
- If it fails:
- create a new connection and move closer to the router.
- Evidence to keep:
- date you checked the password (never write the password itself in shared notes).

Create a new internet connection
- Who:
- you.
- How:
- in System Settings > Internet, set up a new internet connection, making sure you pick the correct network and the console gets a strong signal.
- Result that matters:
- whether the new connection passes the connection test.
- If it passes:
- the old connection settings were the problem.
- If it fails:
- restart your home network.
- Evidence to keep:
- network name chosen and the test result.

Move the console closer and clear interference
- Who:
- you.
- How:
- for a wireless connection, take the console out of the dock and place it within 3 to 5 metres (10 to 15 feet) of the router. Move metal objects and electronics such as filing cabinets, speakers, power strips, glass or cordless phones away from the console and router.
- Result that matters:
- whether the connection test passes closer to the router.
- If it passes:
- signal strength or interference was the cause.
- If it fails even next to the router:
- go on to the next check.
- Evidence to keep:
- distance to the router and what you moved.

What it means
Nintendo explains that codes in this range generally mean an error when Nintendo Switch 2 or Nintendo Switch first tried to connect to the wireless router, usually before getting an IP address. It may happen if the internet settings are wrong or the console cannot find the router. Nintendo says correcting the password usually resolves it. The other steps are a restart, a home network restart, a new connection, distance and interference. Persistent cases go to the router manufacturer.
