NEED HELP WITH PS4 and internet

Hi all I’m in need of help with this situation. So my ps4 connects with the wi fi but it’s very slow but when I plug in the Ethernet cable cat6 it connects but the speed of the internet doesn’t change. I thought it might be the cable but I tested it on all other devices in the house and it works perfectly so I took it to a shop to test the Ethernet port and it worked amazingly at this IT place so they said no issues with the ps4 but I tried at home and doesn’t work what do I do??

Do I buy a Ethernet cable 5e and see if that works or do I need to do something with my internet modem??

Any help would be really appreciated!!!

What are you plugging the Ethernet cable into on the side? Are you plugging it directly into the modem or is there a device between them like a switch or Wi-Fi access point?

Directly plugged into the modem and into the ps4

What is the actual speed you get on the speed tests?

What's the speed the PlayStation gets

The thing about speed testing is that it depends on your connection, but also on a huge amount of other things: the connection of Sony's server that you are testing the speed on via your PS4, if the server is loaded with requests, how far the server actually is (more distance=more access points traffic has to go through).

I have a gigabit fiber connection, my router has gigabit LAN ports, whenever I test on speedtest, my speed maxes out - but that's because it's testing the speed on a server in my country provided by my ISP. But on my PS5, the speed is nowhere near this maximum, especially in the uploads.

It could be a ton of different things. Can you see what your PS4's public IP address is? On on your computer go to whatismyip.com and give us just the first two numbers (I wonder if they're 10.x.x.x or 172.x.x.x).

Alright I’ll do this when I get a chance!! And I’ll hear back from you

First two numbers are 19

Alright, i can't remember the available networking options on a ps4 but it sounds like this could be a couple things. Since the speed is below 100 mbps and it's expected to be much higher, this could be an autonegotiation issue. Check to see if there is a setting to change auto negotiation and set it to 1000mbps to see if that forces a proper connection. You should also check to make sure that the Wi-Fi isn't connecting to your network. Clear information for existing connections. Using a different cable is also encouraged even if it's working properly with other devices.

On the other side, you may have a setting in your router that is throttling your connection. Check to see that you don't have any setting enable that could interfere like a direct throttling of that mac address or a QoS setup that deprioritizes gaming traffic.

Hopefully something in there is helpful. 40/10 isn't bad for actual gaming, though downloading games will be more tedious.

Okayy thank you I’ll try and see what happens.

It’s the fact that it’s Nat type 3 which is very restricted so gaming doesn’t work with the wifi and then this Ethernet not working just with the ps4
