Brand new home has the cheapest and slowest LAN cabling possible (from 30 years ago)

We bought a home, it’s just 2 years old, brand new.

It came wired up with internal LAN network cables, so every room has a LAN port, useful to put access points (APs) to distribute the WiFi over the house.

So I installed a Ubiquiti router and APs recently, amazing product and through that I discovered the network cables they installed are a standard from 30 years called CAT5, and they cap out at 100mbps (!!!).

Meanwhile the internet you get these days is gigabit fiber from 1gpbs to 10gbps. So you’ll be able to use 1-10% of your max speed inside your home.

Why? Because of course Portuguese every single time will cheap out and use the lowest cheapest of anything.

FE here means Fast Ethernet, which is CAT5 @ 100mbps.
