Ethernet runs slower than my wifi?

[Vincen1]

Hi all, so my ps5 wired connection is limited to 93mpbs. WiFi is over 400mpbs. 

my internet is 1GB. I've done every reset opened ports changed the cables reset the lot. Nothing seems to work. 

would any body have any idea why this has happened? 

many thanks

@Vincen1 Have you checked the cable between the PS5 and the sky Hub, one bad core and it will drop back to the 100Mb/s level!
