Running a 10GB LAN with the brains of the whole operation being a Netgear XS716T 10GB switch.
Netgear XS716T switch
Netgear ReadyNAS 626X, 10GB bonded (round robin) connection, stacked with 10TB x 6 WD Red Pros housing media (Plex server), backups, and general storage (including 4k video I am able to edit across the network to a 10GB-enabled PC in my office)
Netgear Nighthawk X10 (R9000), connected via SFP+ to the switch
Netgear EX8000 Extender (Orbi-based mesh)
Google Nest thermostats x 3
7 Smart TVs (6 Samsung) pulling media off the NAS via Plex
Samsung Smart Fridge (Family Hub model with the screen on the door that can show who's at the front door, among other things) and Samsung FlexWash washer and dryer that is accessible by all the TVs (you get notifications on the screen when the refrigerator door is left open or when the clothes have finished their was cycle, for instance)
Rachio 3 smart irrigation controller
Ring Pro doorbell
LTS 5-security camera hub, networked and accessible from anywhere, and Brinks security monitoring everything from the door locks to the garage door, with activity updates pushed to the phones
Pioneer mini-split AC system, wifi enabled, used to maintain and monitor temperature and humidity in a music room with wooden instruments
Amazon Echo Show x 4 (along with smartphones, used to monitor the Ring doorbell, irrigation controller, a split AC system in the music room, and the wall unit in the game room)
Weber Genesis LX II grill with bluetooth temperature probes I check with a tablet on the kitchen counter for monitoring my sweet sweet meats (but an even smarter grill, like some pellet variety, is probably in the near future)
I've been thinking about moving over to a Unifi backbone - The Netgear handles handoffs from the base router to the extender well enough, but I can't help but feel it could be faster. I do love, however, the Nighthawk X10 router, though it is getting long in the tooth. If Netgear, or anyone, made an updated router with SFP+ I'd probably jump on it (If the AX12 had SFP+ this would have been done yesterday, or do I just bite the bullet and upgrade to a 12-stream Wifi6 and aggregate a couple of CAT6's to the switch? Decisions, decisions). As it is, the Nighthawk X10 runs 802.11 ac/ad which still hums right the fuck along.
