I have the following problem and I have the most massive Internet problems on the PS4

Tomorrow & lunchtime but in the evening it is really bad in Fifa I have a 23 latency but in-game it is completely lying and in COD on YT etc

I play in the basement but the LAN connection of my PS4 is broken

We have a 150K line

Is there a way to create your own IP address or Wi-Fi space where only I have access?

You have the two options, of course, but they will most likely not solve your problem.
