Sep 20, 2020 at 10:55 comment added Scott You are correct that I have a cat5 (4 pair) wire, which is connected to a wall plate that terminates to a female RJ11 connector. If I read your answer correctly, I need to leave the incoming cat5 wire connected as it was originally (upstairs) and then run another line from my router back downstairs to the switch?
Sep 17, 2020 at 3:34 comment added Criggie @Ecnerwal see the image in Home Improvement Chat recently for an example of the fun inherent in running new cable. It worked though.
Sep 16, 2020 at 15:45 comment added Ecnerwal @Criggie I'll let the Flying Spaghetti Monster and Cthulhu tear you apart (sharing is caring even when it's Elder Gods and Brand-Spanking New Gods sharing sacrifices, right?) if I come across this sort of abomination. Ewww.
Sep 16, 2020 at 4:36 comment added Criggie @Ecnerwal you're right - cable(wire) is cheap. The hard work (time is money) is in getting it up and down walls in a way that looks undisturbed. If there's a wire in place that goes the right way, I can see the attraction of reusing that, somehow.

Sep 16, 2020 at 2:07 comment added Ecnerwal I would strongly suggest NOT. Cable just isn't that expensive (run a whole new hunk with gig capabilities) and it makes it painful for the next poor schlub to figure out what in the name of Cthulhu you were even thinking...
Sep 16, 2020 at 2:03 comment added ThreePhaseEel They could use the unused pairs of the RJ-45 for 100Base-TX, but that might confuse modern GigE gear that's trying to autonegotiate....
