CAT8 Ethernet port help

So I tried installing some CAT8 Ethernet port socket things so I do not need a long Ethernet cable going through multiple rooms to connect my pc to the router, but after having installed them and testing out the internet speeds, I have seen that it is 10X slower than when it was connected directly to the router and my provider had also changed. I have community fibre 1gb internet but when I connect through the wall sockets it is ~90mb and from a provider called No One Internet. Any help??
