Explanation
What this error means
NW-31295-0 is documented as “cannot connect to a Wi-Fi network. Wi-Fi signal strength may be too weak.” The console couldn’t establish a stable wireless link, usually because of distance, interference, or an overloaded router. It’s a signal issue, addressed by strengthening the connection.

Diagnosis
Most likely causes
| Cause | How likely | Fixable at home? |
|---|---|---|
| Weak Wi-Fi signal or distance from router | Very likely | Yes — move closer / wired |
| Interference from walls or other devices | Likely | Yes — reduce obstructions |
| Router needs a restart | Possible | Yes — power-cycle |
| Too many devices on the band | Possible | Yes — switch band / offload |
Repair
How to fix it
Ordered easiest-first. Try the next step only if the error comes back.
-
Move the console closer to the router
Reduce the distance and clear obstructions — the PS4’s wireless antenna is more sensitive to weak signal than many devices.
-
Use a wired connection
A LAN cable removes signal strength from the equation entirely and is the most reliable fix.
-
Power-cycle the router
Unplug it for a few minutes and restart; a congested router often regains a usable signal after a reboot.
-
Reduce interference
Keep the console and router away from microwaves, cordless phones, and thick walls; try the 5 GHz band if both are close.
-
Offload other devices
Too many devices on the same band weaken throughput — disconnect idle ones or move some to a different band.
Escalation
When it's not your fault
Signs the problem is on Sony's side — or in the hardware — rather than anything you can change:
- Other devices in the same spot also show weak Wi-Fi.
- It improves dramatically when you move the console near the router.
- The router covers the rest of the house poorly too.
Questions
FAQ
Why does my PS4 struggle when my phone is fine?
Consoles tolerate weak Wi-Fi worse than phones. A signal that browses on a phone can still be too weak for the PS4’s stricter connection — moving closer or going wired usually settles it.
Is a Wi-Fi extender or powerline worth it?
An extender or powerline adapter can help where the router is far away; a direct cable is best of all for stability.
2.4 GHz or 5 GHz?
5 GHz is faster but shorter-range; 2.4 GHz reaches further but is more congested. If the console is near the router, 5 GHz often gives a stronger, cleaner link.
