Do I need to change settings when I plug in an Ethernet cable?

Yes. The PS5 does not switch to a LAN connection automatically. You must go into network settings and select LAN cable.

What should I check if my PS5 does not detect the Ethernet cable?

Make sure the cable is properly seated, try a different cable to rule out faults, and check your router configuration to ensure the port is not reserved for another device.

How do I stop my PS5 from defaulting back to Wi-Fi?

Go into the network settings and disable the Wi-Fi card entirely, then remove your saved Wi-Fi login information.

Why does my wired connection keep dropping after I turn on the console?

Some users report brief disconnections shortly after booting. This might be a software glitch, or the physical LAN port on the console could be loose.

Why Your PS5 Won't Recognize an Ethernet Cable

Your PS5 will not automatically switch to a wired connection when you plug in an Ethernet cable. You have to open network settings and manually select the LAN cable option.

If the console is not detecting the cable, check that it is seated properly in the port and try a different cable to rule out a defect. A loose fitting port on the console itself can cause connection drops, and your router settings might have the port reserved for something like IPTV.

For persistent disconnections, try rebooting the console. Adding a cheap LAN switch between your router and console can fix ongoing dropouts. To ensure the system uses the wired connection, disable the Wi-Fi card entirely and delete your saved network login info.

Why Your PS5 Won't Recognize an Ethernet Cable — infographic

The PS5 typically does not automatically switch to an Ethernet connection when a cable is plugged in, and requires manual selection in the console's settings.

Initial Setup and Troubleshooting

Manual Selection Required: The PS5 does not automatically switch to LAN, even when an Ethernet cable is connected; you must select "LAN cable" in the PS5's network settings. "If she merely plugged it in with ethernet and turned it on, it will still be using wifi. The PS5 does not switch to lan connection automatically."

Check Cable and Port: If the PS5 isn't acknowledging the LAN cable, ensure the cable is properly seated and try a different cable to rule out a faulty one. "Faulty LAN cable?nnFaulty LAN port / socket on the console?nnFaulty LAN port / socket on router?nnRouter not turned on? nnLAN cable not seated properly?"

Router Configuration: Sometimes a router might block the connection or have specific ports reserved, which can prevent the PS5 from recognizing the Ethernet. "This happened to me when I switched to a wired connection. Turns out my router reserve one of its lan port for iptv connection. So, check your router setting."

Common Connectivity Issues

Intermittent Disconnections: Some Users experience LAN disconnections that appear randomly or after turning on the console, even with secure cables. "I don’t think that’s the only possible reason.nFor me, it always happens about 1–2 minutes after turning the ps5 on. It blinks 2–3 times, and after that everything works fine, no matter how long I’m playingnSo it doesnt looks like overheating something"

Loose Port Connections: A loose-fitting LAN port on the PS5 can cause connection issues, sometimes leading to users trying to tape the cable in place. "If your cable is moving 'a centimeter each way', it sounds like your port is fcuked."

PS5 Firmware/Software Glitches: Some Users suspect that firmware or software issues within the PS5 itself can lead to Ethernet recognition problems. "Ultimately I have never found an answer or fix. I can only assume there is either a fault in some Ethernet ports (my PS5 is a first gen model), the firmware or the PS software itself that has never been resolved."

Solutions and Workarounds

Reboot the Console: A simple reboot can sometimes resolve issues where the PS5 fails to detect the Ethernet cable, especially after the router or switch has been turned off. "Reboot the console and it get fixed"

Use a LAN Switch: Introducing a LAN switch between the router and the PS5 has helped some users resolve persistent disconnection problems. "I had it for months and it drove me nuts and caused my portal streams to be WONKY af. Then I bought a TP link LAN switch (kind of a splitter for LAN) for like 10 bucks, hooked it up and BOOM. Disconnects gone."

Disable Wi-Fi: To prevent the PS5 from defaulting to Wi-Fi, disable the Wi-Fi card in the settings and remove any saved Wi-Fi login information. "Make sure you disable the WiFi card in the Ps5 settings and remove log in information for the WiFi network."
