4. Some tips to improve internet connection and fix nw-31205-1 error

The nw-31205-1 error error in PS4 occurs when the PS4 fails to connect to the internet. Here are some tips or simple checks you can perform to improve existing internet connection.

  • Use a 2.4 Ghz wifi : You might have heard 2.4 Ghz and 5 Ghz wifi bands. Well the 5 Ghz band is for higher speeds but over a smaller coverage area. And conversely, the 2,4 Ghz band is for slower connection but covers wider area. By switching to 2.4 Ghz wifi, you can be sure that your PS4 is in good range of the wifi coverage.
  • Check if a lot of devices are connected on the network : If a lot of devices are connected on the same network, chances are they will slow down the network. Because each device uses a fixed amount of band-width, the PS4 might not be able to get the working band-width it needs. If that is the case around you, just try again later when there are no active users.
  • Use Ethernet or wired internet : We have mentioned this before. Wired internet is extremely fast and reliable than wireless internet.
