PS4 users change MTU settings to fix PSN sign-in

By Daniel Chubb - Dec 28, 2014

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.

    What’s the point of a free game if this is just gonna happen again… All for a movie that can put innocent lives at risk. A WAR for money and Oil. -TO THE YOUTH= Instead of complaining about psn go buy WEAPON’S & AMMO before the government take all our rights away. Find the truth America!

  • Tanya

    It worked for a few hours for us but now it won’t let anyone sign into psn anymore

  • kr3w__kryptic

    It gave me about 30 min of online gameplay, then disconnected and continued the error

  • alphadu100or

    same mess in France ; no way to log on PSN yet and still the nice NW error code ! Changing MTU has not being helping and I agree shall rather add to the mess than anything else . Better to keep sitting on ass and wait or just play the off line single player mode ….For those who already went through that, remember last time Sony has been hacked ( mmm 2011 ? ) they needed about 3 weeks to fix it ! Lets wait and see if they got better !

  • aliwinters506

    This fixed it for me awesome thank you

  • I don’t have issues with signing in, I am however having problems redeeming that code to pick 1 of 4 free games. I keep getting Undefined. It’d be nice if the support forums at least had ONE Sony employee at least acknowledge this “undefined” problem.

    • justerthought

      lol better yet, just play the PS4 single player games offline until it gets fixed, because they run better than the XB1 version. No sense in accepting less just because you lack patience.

    • PJackson

      Xbox having similar issues. So no freedom there lol

      • Ian Forbes

        Xbox is the best.. not one problem, mine was back on end of Christmas day .00:01am boxing day and no problem since..Same as my friends on xbox live 360’s and One’s.. What a team Microsoft are

        • PJackson

          Actually XBox Live had issues for multiple days. Their servers were not back up fully and without flaw until monday this week. And even then they were sketchy and would go in and out. Trust me, I watch PSN and Xbox servers all day long.

        • Ian Forbes

          errm no we were fully back online with xbox one early boxing day, xbox store & apps and playing fifa online with friends. Only problem for me & friends was xmas day.. There are guys at my work who still cant sign into there ps4

        • PJackson

          Actually no you weren’t. I took enough support calls for Xbox because people couldn’t get into their Xbox Live to know. I stared at their bloody website every hour to see if it came up. BUT I digress. Not EVERYONE has the issues. For every 3-5 people I had call me for support, 1 was on Xbox live. The same exact issue with PSN. For instance I’m on PSN just fine. So, forgive me for being skeptic when the Xbox and PSN servers are my office. In a matter of speaking.

  • justerthought

    There is a problem with all this MTU advice. People are messing with the MTU without even knowing what it does. They are trusting without requiring any proof or explanation, and just changing the value like it’s a secret sauce trade secret.

    The MTU size is related to the data packet size and should be as big as possible for best performance. If it’s too high for the network, data packets become corrupt. 1500 is the standard for most ISP’s for reliable transfers. If you lower the MTU size because the PSN network it not up to speed yet, you are effectively spamming the network with an increased number of data packet traffic, causing further DOS denial of service issues. A data transfer always needs a header at the front, but the packet size it is carrying should be as big as possible, otherwise more data packets have to be sent, causing more network traffic. That makes matters worse.

    Yes if a network is under stress while it’s being repaired, a smaller packet size will improve your personal transfer success rate during that period, but it is at the expense of everyone else and makes it harder to get things back to normal. Why can’t people just be patient and wait for Sony to fix it. The thing will be up and running soon, but it will take longer if everyone is spamming the network with small file fragments.

I you can’t first get an empty hardrive and go on the of then download it on the hard drive then go to you ps4 and hold the power button it will enter safe mode when you get there click storage and download it like that the only problem is that if your a new user u can’t sign in but the good news in that Sony opens tomorrow at 6:00am so download

    • justerthought

      Why would a novice want to expose himself to all that fuss when all he has to do is wait a few days for Sony to fix it. It’s not like it’s the end of the world and we only have a few days left to live. Patience.

    It worked for us – first use of PS4 since Christmas Day. We had tried ‘normally’ this evening first, before giving the MTU option a go, so I know that it was definitely the MTU change that did the trick. Thank you to all who helped find a solution.

    • David Phillips

    Changing MTU doesn’t work for me. Actually makes it worse as it takes like 10x longer to return the NW error message. Getting fed up with console gaming…

    • Toast

    wow thx so much you are a lgend

  • Joe Bo

    Worked for myself. When your connection keeps timing out, it’s more stable to send smaller packets vs larger. This will only work for users that are still getting the above NW 8 ERROR Message. If one is still getting a different type of error, more than likely it will not work.
