UniFi U7 Pro (5-pack)

Yes get that unifi pack makes sense. I’d probably get a unifi  router too to get access to all the features.

Unifi is great. Complete control over your whole network.

Unifi will be the most reliable with the most features without getting into enterprise solutions.

Unifi is worth it if you can afford it

LOL if you have concerns about Google / Amazon, you may not be feeling much better w/ TP-Link (China). If you have an ethernet cable between the two, as you mentioned you do, I would go with a very simple Ubiquiti setup. 1. Unifi Express 7 ~ plug this in as your "main" node. 2. Some Ubiquiti WiFi7 Access Point ~ plug this in via ethernet + PoE injector. This setup should roughly cost $350, and you'll be on Ubiquiti, which is arguably the best platform out there.

I don't know why availability would be an issue. All the items are in stock. This is what you would need for a "complete" setup. 1. https://store.ui.com/us/en/products/ux7 -- That's your main unit. They are just as plug-and-play as most consumer routers these days. 2. https://store.ui.com/us/en/category/all-wifi/products/u7-pro-wall -- Ubiquiti has a LOT of access points. I'm not sure what your ethernet cable terminates. If it terminates into a wall plate, then you may want one of the nice wall mounted ones. If it terminates in the ceiling or in a cabinet, then maybe you choose a different one. 3. https://store.ui.com/us/en/category/accessories-poe-power/collections/pro-store-poe-and-power-adapters/products/u-poe-plus -- That's the PoE injector for your second access point. To your questions... Configuration and management: Honestly if you're even slightly network savvy, it's so much cleaner and nicer than the other systems. The Asus / TP-Link stuff is now either typically locked in an app or has a crappy web UI with infrequent updates. Google WiFi is fine. I have it for my parents, but you don't get much control. At least it "just works" most of the time. Range: In my experience, much more than the Google WiFi Nest Pro. Similar to you, I installed that at my parents' house. I upgraded them from the previous Google WiFi system, and I found the range got a bit worse, but if you're in range, the speeds are much better. PoE Injector -- Most Ubiquiti stuff is powered by what's called "power over ethernet." It atually sends a DC current over the cable. It provides both power and data to the access point. For homes / businesses that require multiple access points, it's so convenient to just drop an ethernet line where you want to add the access point, versus needing a separate power source. Most mid-range or high-end Ubiquiti stuff has ethernet ports that are already "PoE enabled." With the device I recommended to you, the ethernet port there doesn't have PoE, so you need an "injector" which takes wall power and sends it through the ethernet line. An alternative device is the Dream Router 7. https://store.ui.com/us/en/products/udr7 -- One of the ethernet ports on this device is a PoE port, so in this case, you wouldn't need the injector. BTW - I agree it's awkwardly hard to tell if wired backhaul is working w/ the Google Home app. As I mentioned, I have it set up for my parents w/ 3 nodes, all wired, and I find it so frustrating how NOT intuitive it is. Like, they really hide the visibility of it. That being said, it DOES pretty much "just work" for my parents. You said you "added" the Nest Pro. Google doesn't allow you to run mixed mode. I'm assuming you have swapped both old units out for the newer Nest Pro, right?

Get one of these. https://store.ui.com/us/en/category/cloud-gateways-compact Add this to power access points: https://store.ui.com/us/en/category/switching-utility/collections/pro-ultra/products/usw-ultra-60w Then add a U6 Pro or U7 Pro. https://store.ui.com/us/en/category/wifi-flagship No subscriptions needed. Beautiful interface to manage your entire network. Up to 8 different wifi SSIDs. You can keep your kids on one, iot on another, etc. Set different policies per network.

I recently upgraded my APs to ubiquity U7 pro, I can really recommend an UniFi setup

Unifi is great, but if you rely on wireless mesh backhaul, I think Eero performs better. If your home is wired for Ethernet and you can get the access points where you want them, then Unifi is the better overall system as long as you don’t mind tending to it. Unifi really seems designed for a setup with wired backhaul and ceiling mounted access points, which office buildings usually have and older homes may not. In my experience, Eero is better in terms of wireless performance, but Unifi was better as a router. I had two Unifi U7 Pros and a Cloud Gateway Ultra. My two Eero Max 7s perform much better with wireless backhaul than Unifi did in comparison. 6ghz performance was also vastly better. Unifi turned me off with their U7 Pros. They were flakey on launch day, then improved over the course of a year, but then very quickly they released a V2 U7 Pro with internal revisions (i.e., hardware fix) and then another newer variant (U7 XG Pro or something). They took forever to support MLO, and it was not available for mesh backhaul. This was my first Unifi system. Zero complaints about the gateway, features, etc., but wireless wasn’t great in my setup, even after setting up wired backhaul using MOCA adapters.

Not wired. But I have wireless mesh with another U7 PRO and U7 Long Range. Works great

switch to unifi from google mesh. Much happier

Yep I'll second the U7 Pro. I actually only have one as it covers my 1800sq ft split level great.
