Upgrading home network

[ArvoX]

Right now I have a crapy internet connection over the phone line and is only using the wifi router from my ISP.

 

But I am about to get a new fiber line in the house so I want to upgrade my home network to get more stable and better corvages.

The new connection will go in in the basement.

I thougth about gette a UniFi® Security Gateway as a router but is not shure if it is powerful enough for the 1 GB fiber connection.
I like it for its small size and that it can be mounted on the wall.

In the route i plan to use a UniFi® Switch Lite 8 PoE that splits up to a UniFi® Flex Mini Switch used for the office (gaming + nas) in the basement
and a single line to the upstares where I plan to use a UniFi® Flex Switch to power 2 UniFi® 6 Lite Access Point.

Does this setup make sense or should I go in a different direction?

I have to share the connection with the upstares neighbor so I thougth about gette an EdgeRouter X to place in front of my setup to make the shared (to enshure that each apartment is getting atleast ½ GB net)
but it is out of stock rigth now os is there a better alternative?

I hobe some of you could help my get greate home network setup.

1. The USG should be able to handle a 1Gbps internet connection on the latest firmware with no issues.
2. You’ll need to decide where you’ll host the UniFi controller: on a LAN-connected device and/or in the cloud. For local, there’s the UniFi Cloud Key (gen 2) if you want to keep everything integrated with UniFi, but you can just as well install it on a PC or Raspberry Pi. The only problem with PC is that if your PC loses the file or it gets corrupt, you lose your configuration and have to start over.
3. You don’t need an ER-X for this application. The ER-X is basically its own firewall/router and can possibly be subsituted for the USG. Anyway, for the upstairs neighbour, all you need to do is create a separate VLAN through the UniFi Controller on one of the UniFi Switch Lite PoE ports, then run an ethernet cable from that port to them. They can terminate in their own switch/AP, but your controller will handle DHCP.
4. Look here for a guide on traffic control.
