How To Fix Error NW-31201-7
As i mentioned above network issues can be very hard to fix without knowing the individuals specific problem. I will attempt to give my best possible answers on what you can do as a checklist to see what is wrong.
- It is unlikely that PSN is down, but it is worth checking the website or Twitter page to see if they have announced any network outages.
- Check your home network. Are you able to access the internet using other devices? For example, can you access a website on your laptop that is connected to the home wifi?
- If the wifi is working fine for other devices, try restarting the PS4.
- If restarting the PS4 didnt work, check to see if there is something else in the house that is using a lot of the bandwidth on your network. Someone who is downloading games or streaming HD video could cause a slow network connection to fall down.
- Restart your router. The PS4 seems a little more sensitive to network issues compared to other devices. A router restart might resolve the issue. Restarting the PS4 might also be a good idea when the router has restarted.
