So i have a Motorola sb6121. I also have an Tp-link Archer C7. I want to get Ethernet into my room, so i went into my my panel and saw something. A bunch of labeled hanging Ethernet cables hanging there, with one labeled "Living Room". The labeled "Living Room" is plugged into my modem, and my router is in the living room. So i installed a switch, and i got Ethernet in "Bedroom 2", and none to the router. So naturally, i googled it. When I googled it, i was told my configuration won't work. The issue is that i can't move these cables and plug them directly into my router, so i need a solution. Can anyone help? Thank you!
