Imagine you wake up one day and suddenly find your PS4 not being able to connect to the internet. You check the connection from your phone and PC and yes, it works fine in these devices but your console is acting up. Further, you get an error message code NW-31247-7.
Well, this can be a bit annoying at times. Without the internet, you won’t be able to download any updates, patches, and games. Even worse, some games like Fortnite and PUBG will not even work in your system and that can be very disappointing.
There is no fix from Sony regarding this error message but there are some people on the internet who have managed to solve this error.
Today we are going to provide you these fixes and also the reasons behind this error. Let’s get started.
Reasons for the NW-31247-7 error code
There are quite a few reasons for this error message, some of them are given below:
Bad DNS Server
If you are not using the default DNS server and the server that you are actually using cannot manage to connect with ease, this error message can occur. The NW-31247-7 error is basically a connection timeout i.e. an error that occurs when there is no stable connection. Make sure you are using a good DNS server. Also, check the DNS server that you are entering. Sometimes people tend to make mistakes while entering the server IP and then end up facing this problem.
PS4 Network Card Issue
Just like PC and smartphones, the PS4 also has a separate network card that enables the system to connect to the internet. This error can also occur if there is any problem in the network card of your system. If this is the case, then you need to repair it with the help of a technician or use your warranty if you have it.
Sometimes the fault rests on either your router or your ISP. Your router can also have a DNS server and if your ISP has done some mistake setting it up then, this error can occur. To fix it, simply contact your ISP and they’ll definitely solve it for you.
Fixes for the NW-31247-7 error code
To fix the NW-31247-7 Error code, you can follow the methods described below. While the methods are pretty easy to follow, we cannot guarantee the fix. Especially if you have a bad network card. In that case, you’d need the help of a specialized PS4 technician.
Fix 1: Reconfigure your DNS server
This solution is the most common one for the NW-31247-7 error code. In most of the cases, the error code happens because the DNS is not set up properly or the DNS that you have set up is pretty bad.
To fix it, you can use the default DNS server. If the default server doesn’t work then use a DNS server from Cloudflare or google DNS and try again. Follow the steps below:
- Traverse to the “Set up Internet Connection” inside Settings > Network on your PS4.
- Choose the kind of connection you have. Wi-fi or LAN. Use the wired connection if the wi-fi one doesn’t work.
- Choose the Custom setup option and run through all the settings until you get to the DNS setting.
- Switch DNS Setting to Manual and Enter the google’s DNS server i.e. Primary is 18.104.22.168 and Secondary is 22.214.171.124
- If this doesn’t work then you can also use Cloudflare, OpenDNS, or any other DNS that might work.
Check if the error is fixed. If it is not then move on to the second fix
Fix 2: Router Connection fix
Another reason why the error occurs is cos of the Router. To fix the router connection issue, the first thing you need to do is get your PS4 and router close to each other and see if the distance is causing the issue.
You can also switch to the Wired connection to see if the error can be fixed. Another thing you can do is that you can reset your router and PS4.
Just hit the reset button on your router and it will quickly reset, same with the PS4, turn it off and turn it on again.
You can also try fully unplugging both these devices and leaving them in off state for half an hour. Plug them back in again and see if the error persists. There is a factory reset option on your router as well, press the reset button for 30 seconds and it should clear all the cache and reset properly. Check if your router is updated to the latest firmware too. This can also cause the error.
If these router fixes still don’t work, see if the problem is on the ISP side. Check on your ISP’s status and ask your friends using the same ISP if they are able to connect.
You can definitely phone your ISP ask them for help. There is yet another reason too if a lot of people in your home are connected and using the internet, this problem can occur. The congestion of the network is a huge problem for the PS4.
If you are using the Ethernet cable, try using another port on the router to see what happens. Also, try changing the cable itself. Maybe the problem lies there. There is no single reason for this error and no single fix so, you need to try a lot of methods at once!
Fix 3: Service Center
Yes, guys, we have got some bad news for you. If the fixes above do not work then you have no options but to go to a PS4 Service center and ask for a repair. If you have a warranty, claim it. The error can occur because of that hardware failure. Even if you don’t have a warranty, do not worry. It will not cost that much to fix the network card or replace it.
