One Network Cable Two Network Connections

I know ethernet only needs 4 wires so that would not be a problem but would the connections interfere with each other or work without issues.
One network cable two network connections. You must first connect the ethernet adapter s to your mac if you don t have more than one ethernet port. Connect one end of the ethernet cable into to the ethernet port of the primary router and the other end into the ethernet port of the secondary router. Superuser reader ravenix wants to know if it is possible to run two ethernet connections over the same cable. Attach one end of the cable to the port available on pc or ethernet device.
Right click or tap and hold the connection you want to enable and choose enable. Check the back or the bottom of your router for the address. I would like to connect two lans from one pc. The address might either be a link or a series of numbers.
Using an ethernet cable for each of the two routers plug one end of each cable into the lan or similar port on the back of each router then plug each of the cables into your mac s ethernet ports. If prompted enter an admin password or confirm the action. Go to secondary router s settings page and login with credentials. Repeat steps 1 2 and 3 from above to access the network connections screen.
Now connect the rest of the ethernet devices with the switch by making use of ethernet cables. The first network will be used for application software and the second for internet and e mail.
