EAP670

Unifi is no easier/harder than Omada. I'd steer clear of Mikrotik for Wifi unless you *really* know what you're doing.

While running cable/fiber is the "best" option, I do recognize it's not always an option. I have a different orientation, but similar needs and I'm using TP Link Omada. It's been great and going strong for about 3 years now. Setup was not that difficult, and it has more advanced features if you want them. You will need a router, a switch, at least one access point for each building, and a bridge kit. There are newer options now, but when I put my system together I went; - ER605 V2 router - OC200 controller. Not absolutely necessary, but makes it way easier as it basically plug-n-play instead of using the cloud version or installing it on my own machine. It's a little slow, but it gets the job done. - EAP610 access point in the house. - EAP225 outdoor access points, x2. These can be used in a wireless backhaul quite effectively. I did this for a while until I was able to trench in my fiber and backup Cat6A lines to my shop. - TL-SG108PE switch. It's an 8 port (4 POE, 4 Regular) switch that gets you up and running. - EAP215 wireless bridge kit, just added this as it can be used as a Ptp, PtMP, or AP and is managed through the Omada Controller. I just went to Amazon and this hardware listed above is currently $450. No if you add an AP(EAP610) each for buildings 2 and 3, and only one EAP225 for additional outdoor coverage you are at $642. Picking up some patch cables, Cat6A for the in house run to the bridge, maybe a mini-rack and shelves to keep it nice and tidy and you're right around $1000.

I have had both Unifi and Omada. You can't go wrong with either. I switched from Omada because Unifi had cheaper 2.5gb switches at the time. The Unifi controller is a little better than the Omada one.

If you're wiring, choose something better than consumer meshy stuff. I would second the UniFi recommendation, and TP-Link Omada is good also. Wire everything that *can* be wired and save the wifi for those things that can *only* use wifi. The UniFi Cloud Gateway Ultras as the router/controller and whatever switches you need, plus the APs of your choice U6+ or U7+ are good would be a great setup with fully unified management of the network and components.

In consumer world - Asus and TP-Link are the better choices. Eero is great hardware has a subscription model for some needed (IMO) features. I would avoid Netgear, D-Link and Linksys - they are not what they once were and have subscription models, sometimes poor support, and varying reliability and quality. You could also consider gl.Inet Flint devices if you're looking for an all-in-one router, they have gained a very good reputation. I agree that a better choice than any of the above would be Ubiquiti UniFi and TP-Link Omada is also decent - it's different than the consumer gear. Reliability is one of the major points of these prosumer setups. I've been running UniFi for 7 years, it's great.

Just get some real access points like tp-link Omada and run VLAN tagged SSIDs and do the parental controls in the Firewalla. You can also get Firewalla’s access points for even more fine grained control.

Omada, which is made by tp-link and it’s based out of the US has a good product line. It gives you enough to do a lot of stuff with a good price point. Very reliable as well.

I have longer distance at the cabin with just an Omada mesh and it works fine. I get about 150Mb stable, even gamed on it, and my 5G can only do 150-300Mb anyway since it gets a bit crowded there in the summers compared to the base station density. Point to point will do it without breaking a sweat. Would fiber be better? Sure, but I don’t feel like digging a trench and figuring out how to run it cleanly over bedrock either.

Yeah mine is used just for remote work and when my dad visits he streams sports in our guest cabin. Took me almost no time to set up and as a bonus I have WiFi in the whole yard instead of spotty cellular.
