Wow, it's better "in all aspects but mobility"? You're kidding. You may as well complain that batteries suck because the only advantage they have over just plugging something in is portability.
I mean, isn't that true and why almost all of our electronics plug in?

I suppose the difference is that I don't expect my television to run on batteries, but I do expect it to work on wifi.
I build public Wi-Fi networks, you've probably used one of them. AMA if you have Wi-Fi questions. To say it "sucks" is a bit harsh. It's delivering multiple hundreds of Mbps to you via an unlicensed contention-based medium. The air interface is like sending packets over a noisy Ethernet hub; it's impressive it works as well as it does. That said, this article's a good primer on some of the protocol's fundamental chal…

You mean lte-u ,right ? Why is there a difference between the interference of LTE-u to the interference of paid wifi,like wifi-offload ? And.how big is that difference ?
The biggest issue is that we would be the company that is providing the WiFi offload and the paid WiFi so we have control over most of the frequency and can channel plan and all that stuff. With LTE-u its going to be a lot harder to channel plan with the cell phone carriers. A lot of the LTE-u installs I bet are going to be contracted out. So to get to the right people to channel plan is going to be a lot of layers.…
You can't add more users to a frequency without the existing users losing something, regardless of how much the LTE-U people sugar coat it.
My loved one went for a junior sysadmin job. They'd decided to remove all the wiring and use wifi for everything because of just the sorta hype mentioned here. Loved one pulled out a Palm Tungsten C and proceeded to crack all their WEP passwords there in the interview. Got the job too ... and the task of putting quite a bit of wiring back.
WEP passwords? What year is it again?

Yes it absolutely does, but it is dependent on the station (the client) doing so. One of my gripes about Wi-Fi is that it delegates too much to the station - your experience is thus dictated by whoever wrote your phone/computer's Wi-Fi chipset driver, and how they interpret the standard. Any Wi-Fi network supports roaming on the network side, you just need all of your access points to use the same SSID, and to dump u…
So on that note, do you have any brands/manufacturers/chipsets that you see as particularly good in terms of being a client? Its always a gamble when I get a new phone/laptop/device if it will work with the multi-AP setup I have in my house, and I'm really tired of getting something and bringing it home only to find it hangs on to the furthest AP for dear life.

I used to live about 1/4 mile away from any other houses, and I never got why people always complained about wifi. In my experience it always worked well, was fairly fullproof, and had fast enough speeds that it was never an issue. 2 years ago I moved into a condo that has 25 wifi APs within range of me right now. Now I get it. Getting one of the high-end tri-band routers as you said did help, but it's still a diffic…
I never heard of a tri-band router before. It's a misnomer because there is no third band, it just means it can handle 2.4GHz but will use two channels of 5GHz at once. There have been other routers in the past that used more than one channel but it sounds very selfish to use in a dense apartment/condo living situation.
But just the fact that the higher end routers handle the extra congestion much better was more the point.
Earlier quoted context omitted.
I splurged on one of the expensive tri-band routers and honestly now the wireless is good enough that I don't care.
What is triband. Can you recommend one?

Read more (page 2) - there is a considerable discussion of channel congestion and interference due to over powered zones and large number of devices.
I did. It's still fairly superficial, and not the focus of the article. What I'm looking for is e.g. an explanation of how MIMO works, or why explicit timeslots were considered useful for 802.11n but not 11b.
If you want a very simplistic explanation, it's like giving you multiple Ethernet cables to improve throughput. (To gloss over all the details about RF and boil it down to the practical benefit: more bandwidth)
Per the article, not everything with MIMO is advertised as 1x1, 2x2, etc. You frequently find WiFi routers mentioning 1T1R (1x1), or 2T2R (2x2). Or maybe just the Chinese routers I look at.
This article is mostly on about interference, which is definitely a big issue in populated areas. But there are definitely issues with Linux and the drivers used by AP manufacturers. There's a project: Make Wi-Fi fast [1] which aims to address these issues.
They're making good progress, especially in environments with a lot of clients. Just having one 802.11b or g client can really ruin throughput for newer devices due to the timesharing algorithm used by default.

Which router do you recommend? Is the 5G band consistently worse than the default (i.e. constant connection drops) or is that just my experience?
