Network switch problem

[zolyomibarna]

Hy everybody.
I have a difficult problem on my home network. I have a TP link archer c9 router in my home, to witch i connected my samsung tv and xbox one through a tplink network swich and my pc wich is connected directly to the router. Both the tv and xbox have internet and maximum speed, but they're undiscoverable on the pc (windows 10) and other way around also. But if i remove the switch and connect them directly to the router they're working fine. I tried different switches and all with the same result... any ideas what could i do? I don't want to have so many cables in the house.

Presumably the TV and xbox work along the lines of DHCP for an IP address, but with a switch they will need to work at the data-link level (mac addresses and ARP broadcasts). Look into making their mac addresses discoverable, or look at any mac address filtering being applied.
