A PS5 that won't connect over a wired LAN (Ethernet) cable is almost always a bad cable or port, a DNS hiccup, or a router setting — not a broken console. Wired troubleshooting is different from the general Wi-Fi and PSN connection fix: you're checking the physical link and the router's wired side. Here's the order.
Fix it
- Swap the Ethernet cable — the #1 wired cause. A kinked, cheap, or damaged cable fails silently. Use a known-good Cat 5e/Cat 6 cable and confirm both ends click into the PS5 and router.
- Try a different router/switch port. A dead LAN port on the router looks like a PS5 fault. Move to another port; check its link light comes on.
- Power-cycle the chain. Unplug the router/modem for 30+ seconds and the PS5 (full shutdown, not Rest Mode). Bring the router up first, let it fully boot, then the PS5 — a stale DHCP lease blocks the connection.
- Set up the wired connection fresh. Settings > Network > Settings > Set Up Internet Connection > Set Up Wired LAN. Let it run Easy first.
- Set DNS manually if it connects but fails the internet step. Re-run setup > Custom > IP Automatic > DHCP None > DNS Manual > 8.8.8.8 / 8.8.4.4 > MTU Automatic. A DNS failure passes the LAN step but fails the internet test.
Read the test result
Test Internet Connection tells you where it breaks:
- Fails at "Obtain IP Address" → physical/router side: cable, port, or DHCP. Swap cable/port and reboot the router.
- Gets IP but fails "Internet Connection" → DNS or the router's WAN/ISP side. Set DNS manually (above); check other devices have internet. A persistent DNS failure that throws a code is covered in the NW-102307-3 DNS error fix.
- Gets internet but fails "PSN" → not your LAN. Check the PSN status page for an outage.
If wired still won't work but Wi-Fi does
That isolates it to the wired path — the cable, the PS5's Ethernet port, or that router port. Test the same cable+port with a laptop: if the laptop gets internet wired, the PS5's LAN port may be at fault (Sony repair); if the laptop also fails, it's the cable/router port.
FAQ
My PS5 won't connect with an Ethernet cable. Swap the cable and try a different router port first — those are the top wired causes. Then power-cycle the router, and set up the wired LAN again.
It gets an IP but says no internet. That's DNS or your router's WAN side. Set DNS manually to 8.8.8.8 / 8.8.4.4 and confirm other devices have internet.
Wi-Fi works but wired doesn't. The problem is the wired path — cable, PS5 LAN port, or router port. Test that cable and port with a laptop to find which.
Should I use wired over Wi-Fi? Yes for gaming — wired is faster and more stable. Once the cable/port issue is fixed, keep it on LAN.
