Lars, thank for the answer. Yes, I am looking at getting rid of the IHC Net Basic box, and if possible to get 10 Gb/s transfer speeds using upgraded plugs and sockets. While opening the IHC box to remove the cables is probably easy, the wall sockets is a total mystery for me. I have invited an electrician to help me with that. But I feel I need to tell him what components I want to use instead, to get the proper results. And here I would very much appreciate some input from you guys.
What would you put instead of the IHC box? Just male sockets directly to the switch, or something link this (https://www.av-cables.dk/patch-panel/skaermet-patch-panel-cat6a-sort-8-port.html) and then patch cables to the switch?
What about the wall sockets? The insides most probably need replacement. I found these, but not sure if this is correct.

I really need suggestion on these.
As for the switches there is a new 2 port ASUS with 10 Gb. For 8 ports, there is a bigger option from Netgear. This part I will take later on when hopefully prices drop to more reasonable level. A small disadvantage right now is that I will not be able to test 10 Gb transfer after upgrading the sockets, and before buying new switches and network card.
