PS4 users change MTU settings to fix PSN sign-in

While thousands of PlayStation 4 owners are still claiming PSN is down today, it looks like changing the PS4 MTU settings is one option to fix PSN sign-in problems. This is exactly the message being spread by gamers to others owning the same console, which also involves the PS3 in some circumstances.

If you cannot sign-in to PSN on December 28, then Down Today users recommend you change your PS4 MTU settings to 1450 instead of 1500. It doesn’t seem to be working for everyone, but there’s hundreds of users at the above website claiming this stopped the NW-31194-8 error message and allowed them to sign-in to PSN again.


You just have to go to the settings menu on your PS4 and then setting up a new internet connection, or edit an existing one. Change the option from automatic to custom, and then set the MTU to 1450.

This is only a temporary fix while Sony sort out the PlayStation Network, which should be online for most people by now. It looks like Sony aimed to make changes to stop future DDOS attacks and the likes of Lizard Squad has promised not to attack Xbox Live and PSN anymore.

Did changing your PS4 MTU settings help you sign-in to PSN again, or are you still getting error messages? The official PSN status page details everything as online, so if you are seeing something different, then we’d love to hear from our readers along with any error codes being experienced.

Sony confirmed the problems with logging in yesterday, and have since told PS3 and PS4 owners to keep trying while PSN services come back fully online.
