PS5 “LAN Cable disconnected - LAN Cable connected”

Does anyone know if this is happening because of a PS5 software issue or what, I replaced my router and the ethernet cable and it still seems to do this, it will really only mainly do it sometimes after the boot up screen when you log into the system. But doesn’t happen if I play a game for hours on end. The Ethernet cord is a good quality one CAT 8 nylon braided (flat)
