The hardware evolution came as a perfect storm over the last 2 years. Started with Bell increasing speeds in my area to 400 Mbps (upgraded to USG-Pro), and wanting to play with the Unifi ecosystem (read rack mount). Then Bell offered Gigabit with the HH3K, from which the Pro evolved into the UDMP. And since early last year with working from home, gf and I, kids (3) home-schooled, all with tablets, cellphones and Team/Zoom meetings at the same time… I must say the network is quite robust. Not a single downtime, great wifi stability (which I prefer over raw speed).
Costly? Sure. Stable? Heck yeah.
Backbone is the US-16-XG (thanks again zoob) which I use as an aggregation switch, while also has UDMP, server and NAS connected at 10Gbps through DAC cables.
