PS5 Error CE-109801-9: network connection failed (fixes)

CE-109801-9 means the PS5 couldn't complete a network connection — it got partway and the handshake failed. It's a connection problem, not a broken console, and the usual culprits are a flaky DNS, a router that needs a reboot, or a momentary PlayStation Network hiccup. Work it in order and it clears fast.

Check PSN status first

Look at the PlayStation Network status page (status.playstation.com). If PSN is down, stop — no setting on your end will fix a server-side outage. Wait it out. This check saves a lot of wasted effort.

Fix it

1. Reboot the console and router. Power the PS5 fully off (hold for the second beep, unplug 30+ seconds), and power-cycle the router (off ~30 seconds, let it fully reconnect). Clears the stale handshake behind most cases.
2. Set a public DNS. Settings → Network → Settings → Set Up Internet Connection → your network → Custom: IP Automatic, DHCP Host Name Do Not Specify, DNS Settings Manual → Primary 8.8.8.8, Secondary 8.8.4.4 (or Cloudflare 1.1.1.1 / 1.0.0.1), MTU Automatic, Proxy Do Not Use. A bad ISP DNS is a top cause of this code — the same custom-DNS path that clears the PS5 Wi-Fi NW-102307-3 DNS error.
3. Go wired. A Wi-Fi console that keeps failing the handshake is the common pattern — an Ethernet cable to the router fixes CE-109801-9 outright in a lot of cases, and is the core fix when the PS5 won't connect to the internet at all.
4. Move closer / reduce congestion if you must stay on Wi-Fi. Walls and a far router cause partial connections that fail this way; a stronger signal where the PS5 sits helps.

If it still won't connect

• Try the 5 GHz band (or 2.4 GHz if you're on 5 GHz) — one band may be congested.
• Set MTU manually to 1500 in the Custom setup if your network needs it.
• Disable any VPN on the router — it breaks the PSN handshake.
• Test the connection (Settings → Network → Connection Status → Test Internet Connection) and note where it fails: if it gets internet but fails "PlayStation Network Sign-In," that points at PSN/account; if it fails earlier, it's your local network.

FAQ

What does CE-109801-9 mean? The PS5 couldn't complete a network connection — a DNS or router handshake failure. Check PSN status, then set a public DNS.

What's the fastest fix? Reboot the console and router, then set DNS to 8.8.8.8. Going wired clinches it for most people.

It connects to the internet but still fails. Run the connection test — if it fails at "PlayStation Network Sign-In," it's PSN or your account, not your home network. Check PSN status.

Could it be Sony's servers? Yes — always check the PSN status page first. If PSN is down, nothing local will help.
