PlayStation Error Code NW-31205-1 — What It Means & How to Fix It

What Does This Error Mean?

NW-31205-1 means your PlayStation cannot connect to the network. The connection attempt failed before it could reach the internet. This is almost always a Wi-Fi, router, or DNS settings issue.

Affected Models

PlayStation 4
PlayStation 4 Slim
PlayStation 4 Pro
PlayStation 5
PlayStation 5 Digital Edition

Common Causes

Your Wi-Fi password was entered incorrectly on the PlayStation
Your router needs a restart to clear a temporary error
The PlayStation's DNS settings are pointing to a slow or broken server
Your PlayStation is too far from the router, causing a weak Wi-Fi signal
Your internet service provider is experiencing an outage in your area

How to Fix It

Restart your router and modem. Unplug them from the wall, wait 30 seconds, then plug them back in. Wait 2 minutes for them to fully reconnect.

This is the fix for the majority of NW-31205-1 errors. Always try this first.
On your PlayStation, go to Settings > Network > Set Up Internet Connection. Delete the current network and reconnect, re-entering your Wi-Fi password carefully.

A mistyped password is a surprisingly common cause of this error.
Change your DNS settings. When setting up the connection, choose 'Custom,' then for DNS enter 8.8.8.8 (Primary) and 8.8.4.4 (Secondary). These are Google's free DNS servers.

Sony's default DNS servers can sometimes be slow or unresponsive. Google's are faster and more reliable.
Move your PlayStation closer to your router, or use a wired Ethernet cable for a more stable connection.

Walls and distance weaken Wi-Fi signals significantly. A cable eliminates this problem entirely.
Check your internet service provider's website or social media for outage reports in your area.

If your ISP is down, there is nothing to do but wait for them to restore service.

When to Call a Professional

NW-31205-1 almost never requires a professional. If you have tried everything and still cannot connect, contact your internet service provider. They can check if there is a line issue or outage affecting your area.

Frequently Asked Questions

Why does my PlayStation keep losing its Wi-Fi connection?

This usually means your Wi-Fi signal is weak where your console is located. Try moving the console closer to the router or using a wired cable. You can also check for interference from other devices like microwaves or cordless phones.

What does DNS mean and why does changing it help?

DNS is like a phone book for the internet — it translates website names into addresses. If your DNS server is slow or broken, your PlayStation cannot find the servers it needs. Switching to Google's DNS (8.8.8.8) is fast, free, and often fixes connection errors.

Should I use a wired connection or Wi-Fi for my PlayStation?

Wired (Ethernet) is always better for gaming consoles. It is faster, more stable, and has much lower latency (ping) than Wi-Fi. If your router is far away, a long Ethernet cable or a powerline adapter can help.
