Problem expanding network
I am using a sky q hub so only has 2 Ethernet ports one going to tv one going main pc. I am trying to use a switch to add another pc to network. The main pc is constant and strong but the second pc connects, identifies then cuts out after showing as identified. I have tried 2 switch’s one brand new and one borrowed and I have connection to both pcs fine when they are connected direct and all wires are working as have connected directly with them. Have also tried a static ip as well.
If any on could help me would be amazing as I am at a loss thank you
