Got my PSP back on the internet
The PSP can not do the new WPA2 or WPA3 encryption for wireless. Also the PSP does not have any way to connect to Ethernet. But I came up with a solution, I got an old WiFi bridge that can do WPA (the new WiFi mesh network does not support WPA, as it to old and considered less secure) So the old WiFi bride I put on low power (so it should not have much travel distance) and added MAC address filtering only accept MAC addresses I tell it about, and put the PSP’s MAC address into it. Then finally I turned of SSID broadcasting, to make it harder to find. So now my PSP can rejoin my home network.
