Hello, I have a very long Ethernet cable going from my router in my office to my bedroom (gaming computer) that frequently cuts out a lot for short periods of time, and I was thinking to move my modem and router to my bedroom because I would have shorter/better Ethernet cables that wouldn't cut out. The long cable would stay (that would go into a bunch of splitters), it would just have little to no effect to my work computers and printers in my office. My bedroom already has a coax outlet.
