Restart the console and create a new connection
- Who:
- you.
- How:
- restart the console from Power Options, then set up a new internet connection. Test the connection after each change.
- Result that matters:
- whether the connection test passes.

- check the DNS and proxy settings.
- Evidence to keep:
- the test result after each step.

Check DNS and proxy settings
- Who:
- you.
- How:
- in the console's internet settings, change DNS from Manual to Automatic if your network does not need a manual value. If you are not connected through a proxy, disable the proxy settings.
- Result that matters:
- whether the console connects after the change.
- If it connects:
- the DNS or proxy setting was the cause.
- If it fails:
- power cycle your network and enter an alternate DNS.
- Evidence to keep:
- DNS and proxy settings 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.

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.
