I’m pretty new with networking but I have Frontier Fiber, they installed a Moca adapter in my living room that is then connected to a wireless router. I want to get a wired connection to my room to my PC. Can I just connect another MOCA adapter to a coax jack in my room and then connect an ethernet cable to my PC? Will this cause my bandwidth to be cut in half? or would I still be able to get full down and up speeds? If I wanted to connected to both my xbox and my PC am I able to connect the moca adapter to a network switch and then connect both my xbox and PC that way?

Any help is appreciated!
