Restart the console and create a new connection
- Who:
- you.
- How:
- restart the console from Power Options. On wireless, set up a new internet connection to the correct network with a strong signal.
- Result that matters:
- whether the connection test passes.

- the console or its old connection was the issue.
- If it fails:
- check the DNS setting.
- Evidence to keep:
- connection type and the test result.

Check the DNS setting
- Who:
- you.
- How:
- in the console's internet settings, look at DNS. If it is Manual but your network does not need it, change it to Automatic. If your network requires a specific DNS, ask the network administrator.
- Result that matters:
- whether the console connects with the corrected setting.
- If it connects:
- the DNS entry was the cause.
- If it fails:
- power cycle your home network and enter an alternate DNS.
- Evidence to keep:
- DNS setting before and after.

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.

Enter an alternate DNS or try later
- Who:
- you.
- How:
- manually enter an alternate DNS as Nintendo describes. If it still fails, try again later, as an issue with your internet service may clear.
- Result that matters:
- whether the console connects with the alternate DNS or later on.
- If it connects:
- the DNS service you were using was the problem.
- If it never connects:
- contact the router manufacturer about firmware and a reset.
- Evidence to keep:
- DNS values used and times of the attempts.
