He is talking about trying to get 200mbps on the 5ghz band. Not 2.4ghz.
There is plenty of space on 5ghz. 2.4ghz should be used as a secondary radio nowadays anyway.
EDIT:Also, if anyone had looked at the channel the OP is using, they would have already known that he is using 5ghz.
No it is not irrelevant and yes I knew he was on 5Ghz and everything I said applies to 5Ghz also.
Not yet 2 days ago I was testing on a r7000 and "auto" on 5Ghz set the 5Ghz channel up right on top of another 5Ghz wifi AP that was advertising. And it wasn't exactly on top either it was disjoint. This was with gobs of other completely unused spectrum available on the 5Ghz band.
I think the idea some people have is "auto" causes the AP radio to seek out the best band, that is the band that no other wifi AP is using. But in the real world not in this fantasy of how things are supposed to work, in the world of how things ACTUALLY work, "auto" basically tells the wifi radio to do whatever the heck it wants to do, and what it often wants to do is the stupid thing.

I'm not sure if you guys read my 2nd post correctly.
When I pick any channel on the 5Ghz Wi-Fi frequency band (channel width 20mhz), I don't get my full internet speeds. I only get my full internet speeds when I set the channel to auto and auto always selects channel 52.

Auto channel ignores channel width settings, so either set width, channel and extension properly or just use Auto.
What were the results on 5GHz band with 40MHz or 80MHz channel selected? _________________ "The woods are lovely, dark and deep,

However I'm making lots of assumptions about wireless basic, advanced settings and client capabilities (1x1/2x2/3x3).
It is best to keep it simple for now. Since Auto always picks 52 use this channel as reference for manual settings tests.
What I mean to say is 40 MHz channel width choose 52 Upper (select Lower) or 80 MHz choose 52+UU (select 52+LL).
Then you can compare the results to previous tests without going into the gritty details about wireless understandings.

"auto" is the router scanning the area and finding whats the best channel to use. Otherwise, it would not be there. In fact, if the router truly did the opposite of what I just said it does, may as well pull it then and have everyone set their frequency to manually!
And where exactly was the interference coming from? if the router showed something like -87, I honestly would not worry about it.
WiFi analyzer apps are only useful for 2.4ghz. If its 5ghz, then it most likely may be in an area where this is TONS of 5ghz interference. otherwise, its a waste of time and energy to wave your phone around while the WiFi analyzer app spams advertisements at you until you actually buy the app itself.
No, you did not know he was using 5ghz because at the end of your post you said this

When possible for highest throughput use 5Ghz, and set the channels you use to ones that nobody else is using, run 80Mhz channel widths, and move the AP as close as you can to your wifi client. You should have 5 bars on your client for best throughput.

Ontopic, you also want to play with airtime fairness (understand what it does to the signal -- google it) and keep TPC mitigation factor off as its default, unless you live in the airport right next to a relevant radar (there are a dozen or more radar types if youre interested you can google that too).
You also may consider your clients capabilities and in addition look at Implicit/explicit Beamforming also.
Re: TPC Mitigation; I live near a military airbase, less than 800 meters away as the crow flies, and even blasting at max 1 watt on the radios and TPC mitigation OFF, at the distance I am from the radars they have around it doesn't affect them not even when using the same frequency ranges and its irrelevant as their radar types around are military (and several different types) and thus not susceptible to interference for POS consumer router.

You dont know every users environmental factors, its impossible unless the user knows whats going on around them.
The wifi analyzer I recommend, is good, opensource (so you can audit the code), does not collect ANY data and is free as in free beer.
Ultimately getting to know your specific environment to pick the best channel when you are surrounded by wireless networks is NOT a waste of time, to simply see what the environment is like, how the signal travels around the house and how much is lost and where are the areas that have poor reception is not a good practice to plan your network and is like you say a waste of time, well maybe for you. I think its time well spent in order to make informed decisions for best result and good network planning for the average lay person.
And in that process less experienced people hopefully get to move up 1 level and gain knowledge/understanding.
Auto-Channel makes a short channel analysis and selects a channel with less activity and good quality.
However, it does not have to be the best channel because, as I said, it is only a very short analysis.
and what is good in one moment can be bad 10min later
moreover, auto-channel does not take into account the clients' requirements
There are clients that do not support all channels.
For example, there are firetv sticks that are not DFS certified and only support the lower channels.
If you have such clients then you can't use auto-channel because auto-channel can also select channels that are not supported by the clients.
there are also routers where auto-channel sometimes is stuck and the radio does not start
Therefore, here in the forum is the general consensus that if possible no auto-channel is to use.

If auto-channel could show a report of its analysis in the system log, it would be more useful. Right now, you don't even whether if there was any channel analysis...

I switched from specific channel to "Auto" in Wireless->Basic Settings->Channel, hit "Apply", no such entries in system log. After a while, the following entry was found. No quality and noise results.

I believe that after installing internet connections at customers houses for about 3+ years, I think its safe to say that I already have a good idea of whats going on at the customers house. I never bothered having to set the channel manually because I always got max capacity and good latency.
The only manual change I did make was channel width. But what was on rare occasions. Some devices in the customers house prefer working with 40mhz channel width instead of 80mhz. even when the device was up close, it still will not want to connect to the 5ghz radio running in 80mhz channel width. I meant, it was the customers iphone that had issues with 80mhz channel width, but I am still going to use the word "devices" here. I only recall witnessing this sort of thing twice though hence why I say "on rare occasions"

If you are referring to external 5ghz interference then the same will go for manually setting the channel.
I have told my customers that if a device in their network does not want to connect to the 5ghz radio, have it connect to 2.4ghz instead. In much simpler terms for the customers sake. And it would make sense to do that given that it may be a streaming device like a roku or fire stick that cannot consume more than 100mbps anyway. For devices that can, it would be a nintendo switch, your high end PC, high end laptop and so on.
only on consumer routers running factory stock firmware or mikrotik, I never had auto-channel hang on me. dd-wrt would probably be the only firmware I know of that would have these issues. However, I never really seen it since I do NOT and NEVER WILL install dd-wrt routers at customers houses unless otherwise specified nor have I seen that happen at my house. _________________ For people who are new to the dd-wrt forums >> http://www.catb.org/~esr/faqs/smart-questions.html#rtfm
