There are only two of us now. We have VM 1Gb and I use a Draytek 2927 to connect the router to one of the switches. I do quite a bit of video editing and all my data is on a NAS, so speed is vital when editing files that are 10GB plus, a fast LAN is needed.
Our property has solid walls, so Wi-Fi does not travel well, so I had to add multiple APs for phones and iPads.
I had to put an Access Point into the garage for the Tesla, and the 4 ports are connected to the Gateway, two inverters and the 10Gb Switch.
I think us techies like things to be just right be it PWs, networks or computers.
