So, you can go:
- all in one gateway (modem+router+switch+wifi all in one box)
- all in one modem+router (modem in one box, router+switch+wifi in other box)
- discrete (all separate boxes)
- mesh (mostly separate boxes but instead of cat5/cat6 wired, they use wifi for their own interconnectedness).
Discrete category of solutions gives you most performance and most flexibility, but requires Ethernet/cat5/cat5e/cat6/cat6a backbone, which you have. You can mix and match vendors and companies usually to no performance detriment, but keeping things with the same vendor will make things easier to manage (either because they offer the ability to configure more devices from a single UI, or because itâs helpful to have one marketing department inventing terminology over having multiple marketing departments inventing different terminology).
Hereâs a starter setup with discrete:
- Arris 8200 modem (you buy it and own it physically, ISP owns the config)
- Ubiquiti USG https://www.ubnt.com/unifi-routing/usg/
- Ubiquiti Unifi 8 150w switch https://www.ubnt.com/unifi-switching/unifi-switch-8-150w/
- n x Ubiquiti Unifi AP-AC-Pro https://www.ubnt.com/unifi/unifi-ap-ac-pro/
You can add accesspoints as needed.
Youâll also need either a small patch panel or you could crimp the connectors directly onto those couple of cables.
Hereâs an alternative discrete setup:
- Arris 8200
- n x Mikrotik hAP ac² https://mikrotik.com/product/hap_ac2
Both of these are super flexible, Mikrotik is insanely flexibile (those boxes are great routers and switches and good wifi APs). Ubiquiti accesspoints have higher raw wifi performance and slightly better range (less slowdown with distance) and you can get one mesh-like networking hop with Ubiquiti and you can set it up using a phone app, or you can install a controller software on a computer for configuration and 24/7 monitoring.
Mikrotik has better wired performance, but somewhat worse wireless performance. Mikrotik can do multiple hops, doesnât need a centralized controller or an app but you can use an app or a controller or ssh if you want to, or a weird Ethernet only protocol, or a combination, it has so many knobs itâs confusing to a lot of people. Most people still just use them for basic routing or as basic APs as above since thatâs all they need. I like using them as travel routers and repeaters and to setup guest networks and to extend wifi, but they work at home too. Theyâre my goto spare routers, but with lots of features comes great complexity - if youâre not enthusiastic about network and need something that you want to get it over with and forget about, but want a discrete setup get the Ubiquiti setup above.
If youâre an enthusiast get the Mikrotik and the Ubiquiti and a Netgear x4s / R7800 or a Linksys wrt3200acm for use with OpenWRT, and try DDWRT, pfSense, pfSense in a VM, VyOS, OpenWRT in a VM, and try rolling your own Linux router or accesspoint using e.g. Debian or Arch.
