It really really really depends on the situation. How big is the home, how fast is the internet, future plans, coverage needs, etc. And budget.

IMO, most people don't spend an appropriate amount on their internet network. They'll spend hundreds per month for internet service from an ISP, but refuse to spend more than $60 on a router to get it from the ISP modem to their $1000 phone. It doesn't make sense, especially when you consider that it's a one-time cost that will serve you for many years; the per month cost of owning it is less than a cup of coffee a month, even if you buy something that's 10x more expensive. People are so resistant to it that is crazy.

Even at $100, you're going to get what you pay for, better than the $60 router, but it's going to fall short of anything that's worth keeping for extended periods of time.

Right now my blind go to, when I don't know anything about someone's situation, is the ubiquiti UDR. It's an all in one device, around $200, with a WiFi 6 access point built in, and four ethernet ports, all 1Gb and two of them have PoE. The limitation is the 1Gbps internet link so anyone with an ISP connection faster than 1Gbps should go with something else. Most don't, so this is my recommendation.

The reason I recommend it is that you can add additional access points to it as needed with basically no additional spend (beyond the ap itself). With two PoE ports, you can add two aps without worrying about whether or not you have power injectors or anything. Adding a small network switch is easy on any of the other two ports if four isn't enough for you, and ubiquiti has some pretty cheap, small switches for that.

The UDR comes with a built in network management device (otherwise known as a "cloud key" in unifi) which puts everything into a single interface. So the access points (both internal and add on), switches, etc are all managed from a single system that's local, and has local sign in, and has a convenient cloud interface which is free to use, and has all the same functionality.

As a starting point, this is excellent. Because having just the UDR you can service a small apartment without any add-ons. If your needs grow, you can build out as needed. If your needs grow beyond the UDR, you can upgrade to the UDM/UDM pro (or similar) and keep using all the add-ons you've purchased. There's room for growth, and ubiquiti has proven themselves to be rather adequate at providing networking for the home. Unless you get into some very advanced features, it should serve whatever needs you have both now and in the future.

My recommendations obviously change depending on the situation. One person I worked with recently, I recommended the UDM pro and a pair of access points, because his ISP connection was in his furnace room. The UDM doesn't have any WiFi built in, and the furnace room is usually a nightmare to get wireless into or out of. The connection will suck. So being able to move his access points (of which he got a couple), out of that area and into more open spaces, was critical. In that case I gifted him a Dell power connect switch and used PoE injectors to power the access points. I was able to provide a very good, very reliable network for him without ongoing difficulty or issues (which was his primary concern). Before this he struggled with the wireless from his ISP modem, and it disconnected and had very poor signal throughout his home.

Since the initial set up, I've heard nothing but good things about it. He's very happy with the system. His situation had some unique challenges, and we even ran ethernet vertically up to his second floor office through what used to be a chimney stack and that had been used to install a forced air duct for the second floor. So the space was only that forced air duct from the furnace. The cable(s) share that space with the air handling duct (but are run outside of the duct for safety), and he has gigabit ethernet jacks in his office to get a reliable connection for his professional systems in the office. He probably doesn't need the Dell switch in the mix, but it gave him extra ports for use for later.

I've done dozens of custom recommendations for people. At this point I'm thinking of making a website to point people to that has all the information about home networking you could need, generalized enough to always be correct. I want to include sections on different manufacturers and why wifi kind of sucks, explanations of different technologies, their benefits, pros and cons, that kind of thing. Etc.... All in one place so I can link people to it and they can learn as much or as little as they want; with pages like recommendations, all time stamped so you know what's current or recent, and deep explainer pages of different technologies and how they work and what benefits and stuff that they have if you want to know more.

It's a huge plan, and it will take me weeks or months to write it all out. I will need to find cheap web hosting for it and get some kind of UI/UX design going for it, and build the whole thing so I can update it without having to work too hard to start the new page entry. Maybe a wiki style? Idk. I'm thinking of calling it something along the lines of "WiFi sucks" or something related... Like wifisucks (dot) com or whatever. I'm sure I'll need help with it, mainly in the UI/UX, but it's something I've been considering doing for a while, just to handle these kinds of questions continually.

I have a blog about it, called untangle the tubes, IIRC, and I go on long, in-depth rants about stuff. But it's highly disorganized and random.
