With Apple no longer in this space, I looked at Ubiquiti and its offerings are too enterprisey for my use. Its HD line is five years old. Its Alien isn't available on Amazon, even from UI's own "Buy at Amazon" link, which makes me wonder about it. I read nothing but bad news on HN about Linksys, Netgear, and Cisco, but am keeping an open mind. I can find almost no objective information about TP-Link.
Are there brands or models I'm overlooking?
For your purposes, I would highly recommend checking out the Unifi Dream Machine (https://store.ui.com/collections/routing-switching/products/... -- not the Pro unless you already have a network rack). It's as close to an AirPort as you can reasonably get these days. You can also get additional Unifi APs if you need more coverage (including any of their outdoor stuff) or use Unifi LTE as a backup conneciton (https://unifi-lte.ui.com/)
I've installed just the Dream Machine in several family members' homes and it's a huge improvement over the nonsense that the ISPs provide them with. Personally, I run a Unifi Security Gateway, Cloud key (Gen 1), and the AC AP PRO and I've been very happy with it. I like that I can selectively upgrade equipment when needed (for example, I upgraded my AP for better range and speed a couple years ago, but I'm still using the same USG that I got back in 2014 or something).
If you're having trouble figuring out what you need and you want to go the Ubiquiti route, feel free to email me (see profile) and I can get you pointed in the right direction.
Manufacturers I think you should consider would be MikroTik, and Netgear's business and SOHO ranges (one step up from the normal consumer stuff).
If you're set on a consumer WiFi router device, Unifi is your best bet. Other than that, Linksys and Asus aren't that horrible, relatively speaking, and you can pick a device with good Open/DDWRT support if you retire it or change your mind down the line.
How important the above is also depends a lot on your requirements in terms of # connections, throughout, and consistency.
The biggest requirement I have is CAKE [1] support as I think it’s an absolutely incredible feature that makes non gigabit/upload limited connections with multiple users much more usable.
Unfortunately, this limits us to a few routers. OpenWRT does it wonderfully, but OpenWRT is only a great choice if you’re a rather technical user and can be around to upgrade it/futz with it as needed. Ubiquiti doesn’t have support yet (I think the edge router has some custom packages you can install, but these aren’t official last I checked).
Eero does support this, and is my current recommendation, but it is worth noting that Eero is locking features behind a subscription plan that costs up to 10$ a month. Want adblocking, a feature that other routers are now adding for free? You have to pay. I seriously doubt this plan is ever going to work for them, but keep it in mind. I’m guessing it’ll eventually morph into a “sign in with your Amazon Prime account” style thing for bonus features/selling your DNS/tracking data to Amazon, but who knows.
Thus, I think Eero is a great stopgap for the next 1-2 years until Ubiquiti stabilizes their Amplifi line and/or finally adds CAKE to the Unifi stuff.
Every once in a while I have to power cycle the bunch, but it’s getting longer between each time (presumably because the firmware updates are working).
Overall they work pretty well for a consumer product and I think they meet all your requirements.
I upgraded my range by adding a couple of Unifi AP's to my existing ISP router. It was less of a commitment than a UDM, and I originally just set them up in standalone mode with no account or cloud presence.
Try this guide. Focussed on Uk, but should work elsewhere. :)
