I. What is the NW-31297-2 error? What are the reasons for this problem?

Some PS4 gamers may experience the NW-31297-2 error code if their console fails to connect to a wireless network. The PS4 cannot communicate with the modem/router, which means that all the console’s online features will not be available, access to the PS Store (PlayStation Store), online transactions or online multiplayer games. While there are a number of reasons why this type of failure could occur, one of the common causes is entering the wrong WiFi password, especially if you are using the WPA security protocol.

When this error occurs, in addition to the incorrect WiFi password just mentioned, it may also be caused by the following reasons.
●The modem/router has become unresponsive
Routers may freeze or become unresponsive from working for long periods of time. At this time, you need to turn off the router, let it rest, and then restart the router after a few minutes of shutdown to ensure that the device is in the best working condition.
●Incompatible wireless security mode
Some PS4 gamers are experiencing WiFi connection issues when using security modes other than WPA, resulting in this error code. At this time, you can try to switch to WPA to check whether the problem is solved.
Note: The full name of WPA is Wi-Fi Protected Access, that is, Wi-Fi network security access. There are three standards: WPA, WPA2 and WPA3. It is a system to protect the security of wireless computer networks (Wi-Fi).
●The wireless network is busy
If your modem/router is handling too many devices at the same time, it may block new connections. You can disconnect other devices from the router to avoid a busy network.
●PS4 software is damaged
In some cases, the PS4 may display the NW-31297-2 error message due to issues with the console software. If you have recently downloaded new PS4 software, it is recommended to restore the device to the time before the software was downloaded.
The above are some possible reasons for the PS4 NW-31297-2 error. When encountering this kind of problem, you can initially solve it by checking whether the WiFi password is correct, restarting the router device, and reconnecting to the network. If the problem still exists, you can solve it by the following methods. We continue to learn.
