PlayStation 4 error code NW-31484-0 means your PS4 is unable to obtain an IP address from your router or network, so it cannot connect to the internet or PlayStation Network. This typically happens because of a DHCP conflict, a router misconfiguration, or a temporary glitch in your home network. The good news is that this is almost always fixable at home without any special tools or technical expertise.

When to Call a Professional

If you have tried all steps above and the PS4 still cannot obtain an IP address, the issue may lie with your Internet Service Provider (ISP) or router hardware. Contact your ISP if no devices on your network can connect, or if your router's DHCP service cannot be enabled. If the PS4's network card hardware is suspected to be faulty — for example, the LAN port is physically damaged or the Wi-Fi adapter is broken — contact PlayStation Support at support.playstation.com or take the console to an authorized Sony repair center. Do not attempt to open or repair the PS4's internal hardware yourself, as this will void your warranty.

Frequently Asked Questions

What does PS4 error NW-31484-0 mean?
Error NW-31484-0 means your PlayStation 4 failed to obtain an IP address from your router or network. Without an IP address, the PS4 cannot communicate on your local network or connect to the internet and PlayStation Network. It is usually caused by a DHCP issue, a router glitch, or a network configuration problem.
Why does my PS4 keep getting NW-31484-0 even after restarting?
If the error keeps coming back after a restart, it is likely caused by a persistent DHCP conflict (two devices fighting over the same IP address), DHCP being disabled on your router, or the DHCP address pool being full. Try assigning a manual static IP address to your PS4 in the network settings, or log into your router and check the DHCP settings to make sure there are available addresses.
Can I fix NW-31484-0 without accessing my router?
Yes, you can try assigning a manual static IP address directly on the PS4 through Settings > Network > Set Up Internet Connection > Custom. Use a manual IP address in the range your router uses (e.g., 192.168.1.150), set the subnet mask to 255.255.255.0, and use the router's IP as the default gateway. This bypasses the automatic DHCP process entirely and often resolves the error without needing to access your router.
Does NW-31484-0 mean my PS4's Wi-Fi is broken?
Not necessarily. NW-31484-0 is a network configuration error, not a hardware failure indicator. In most cases it is caused by a router or DHCP issue rather than a broken Wi-Fi adapter. To rule out hardware, try connecting with an Ethernet cable — if that works fine, your Wi-Fi hardware is likely okay and the problem is related to wireless signal or router settings. If neither Wi-Fi nor a wired connection can get an IP address, contact PlayStation Support.
Will I lose my saved games if I reset PS4 network settings?
No. Restoring default settings on the PS4 (Settings > Initialization > Restore Default Settings) only resets system and network settings — it does not delete your saved games, downloaded games, trophies, or user accounts. Your data stays intact. However, if you perform a full 'Initialize PS4' option, that will erase everything, so make sure to only use 'Restore Default Settings' for fixing this network error.
