I had multiple wired access points in a rental apartment with high wife approval factor by running cables in cup hooks along the ceiling lines. They self-tap into the wall and leave little more damage than would be caused by hanging a picture. I put a hook every 18 or so inches for support, and ran a cable under a door, up the door frame, down a hallway and into the living room (from a bedroom where we had the network gear). From there, I only had to mount the access point and connect everything. The cables were always out of the way, and I used white cables to help hide them against the walls. It wasn't perfect, but the limits of renting are a bit limiting.

I only had two in that place, which was plenty, and we never had bandwidth issues accessing the internet from the wifi.

The fact is, nobody is building homes with wireless access points in mind. Whether rentals, condos, or new homes, they don't have access point hookups. Many are now being wired with Ethernet in the walls, but nothing in the ceiling. A skilled wireless engineer can easily take a floorplan and build a wireless design with access points in ideal locations for maximum coverage and speed. Simply doing this pre-work and installing ethernet in the ceiling at these locations, is all that is required, yet, I have yet to see any builder do it. The same can be done to retrofit rentals as people vacate units and updates/renovations are done, yet, nobody is doing it.

Those that own their home need only to find placements and pay someone to wire them in. The whole thing only needs to be done once, ever, and the locations should be fine for use for the long term.

Fact is, neither builders, nor property owners, nor homeowners seem to have any interest in the practice. The only time I have personally seen or known of any location that is properly wired for wifi, is when someone has hired such wires to be custom installed. If it was done by default, rather than as an afterthought, retrofit or renovation, then it may be more common that people pursue such solutions. The price problem is another major hurdle, though I stand by the analysis of people paying literally several thousand dollars on internet access from an ISP, compared to a few hundred at most for a router during the same timespan (usually 1-3 years). IMO, that's a bit like paying $50,000 over 10 years for access to the highway, but never buying a car worth more than $1000. It's silly.

My main point is, solutions to these problems exist, but people simply won't pay more than a few months worth of ISP fees for their wifi hardware, then they expect it to perform well and last for many years. They will turn a blind eye to the environmental issues that plague them and instead blame everything on lackluster devices that underperform that they will continue to refuse to pay a reasonable amount to actually get quality access equipment.
