Say I have an Ethernet cable running from router to wall port 1, from 1 to wall port 2, from 2 to wall port 3, and then finally to my computer from wall port 3. Does that affect the connection in any way or degrade it?
Yes… that is a series circuit and the last ethernet cabling that did that was thinnet. Unshielded twisted pairs has a length limit and should be home ran to the patch panel
That’s fine. I assume the router patches into a switch box, and the switch box patches into your room?
Better to just run more cables properly but technically no
Every connection takes 10 meters off the maximum run as a rule of thumb. If every cable is terminated perfectly, and every jack exactly to spec, and all the stars are aligned perfectly, it shouldn’t do anything.
What?
