You're welcome!I like the way you explain things! Excellent!
"But instead you can do smart thing with how you design your network. If you know for example a NAS unit in the basement is what will get hit with this traffic."
This is exactly what I'm working towards (in baby steps)!!! So ... 2 wires from the cave to the 2nd floor switch ... maybe a 3rd in case I ever run into problems with either of the 2 I'll be using ... I wouldn't even have to crimp connectors on the end of this 3rd 'backup' wire ... just having the wire in place with a few extra feet on each end would be like 'emergency money in the bank' should anything come up.
Thinking of the 'Wife Factor' in all of this I received some very good news indeed. She is going to go visit her mother (assuming the covid restrictions lift by then) for a week to 10 days when I start her planned mini renovations. That'll save me endless discussions about 'why are you running wires here, there and everywhere' and let me get on with things with no distractions. If she comes back to the installed crown mouldings and a bunch of other stuff she wants me to do ... as long as there's no wires visable all will be good. I'm sure she'll be skype calling in the evenings for updates but ... a little tape on both front and back cameras on my phone for a few days ... and a 'sorry, I can't seem to get the video working on this lousy phone' will take care of that. lol
Yep, and to be honest you can run a few more if you want just for kicks because even if you have runs to the upstairs switch, you can always use a cat5 coupler and connect them directly downstairs. This might come in handy for whatever reason.
LOL!! Your wife sounds like my wife!!! hahahaha!!! I can't do anything without her micromanaging the process and it's easier to just do it when she's not there and she only nit picks the final result. Like my recent UPS installation--why do you need UPSes? Ummm...we have power outages? Like long ones? And I don't want to bug you about resetting all my gear when I'm out in the field since you'll get frustrated? "Oh okay." LOL!
