I have already laid cables at home to which I have now connected the LAN sockets myself. On my PS4, every time it starts, it shows that no LAN cable is connected. Nevertheless, I always have an Internet connection and between 60 and 85 MBits arrive.
Now I wanted to connect my PC with this cable. If I was lucky, the PC would briefly recognize the cable. After about a second the connection was gone again.
Why couldn't my PC recognize the connection and why does the PS4 always show at the beginning that no LAN cable is connected? (With a different LAN cable everything on the PC and PS4 worked without any problems and I use extra new cables at the beginning and at the end) Thank you in advance!
You have probably swapped 2 wires in the permanently installed LAN cable. The cable consists of 4 wire pairs, each pair is twisted. The LAN connection already works with 2 wire pairs. One in the sending direction (Tx), the 2nd in the receiving direction (Rx). This is sufficient for a "slow" LAN. The best thing to do is to buy a LAN checker, available for less than 10 euro. With this you send voltage to your wires 1-8 in a slow cycle, the LEDs at the other end light up simultaneously. Then if the order is wrong, you are at fault. If everything is displayed correctly and it still doesn't work, then you have an intersection of 2 wire pairs.

Thank you so much I will have to look again. I'm just surprised that 80mbits still mostly reach the ps4. When I connected it, I knew there were two ways to lay the wires. Could that also be a reason or are these assignments both equally fast?
