What conditions should I create in order to get 800 Mbps in the local network over the air?

Question

WiFi

There is a TP-Link C80 (AC1900) router, a server and 2 clients. The server and one of the clients are connected to the router by wire, and the second client is connected via 5G, where the connection status of the client indicates the speed of 867Mbps. Although the router can work at 1300, but that's not the point, even if it gives real 867.
In fact, connecting a client via a local network to a server via a gigabit wire takes 7 seconds, and connecting another client via wi-fi takes 25 seconds. Further work with the base is also 3-4 times slower over the air. And all this takes place in an "office" of 6 square meters, where one PC is on the bedside table, the other is on the window, the third is on the floor.

Here I would like to know: what conditions need to be created so that I can get rid of the wire at short distances?

Answer 1

TP Link C80 (AC1900)

good router, and inexpensive (c)

Although the router can work at 1300,

sell stickers ABS, CBC, EBD, etc. for your Zhiguli (c)
advice: go to the Mikrotik website
https://mikrotik.com/products/group/ethernet-routers
look at prices and specifications ( testresults ), for example https://mikrotik.com/product/RB750r2#fndtn -testresults
and you think why is it so
. than $99
https://mikrotik.com/product/RB2011iL-IN
differs from $199

and others
, you can exclude your water gun (c) "Big jackpot" for $49 from comparison

Answer 2

buy a good wifi point and wifi card for PC
1300 is the total speed of the router for all wifi channels apparently, so your 867 is good.
How much speed is issued when copying a large file?

Answer 3

867Mbps is the total channel speed of two 5Ghz radio modules of your router, provided that you use a channel with a width of 80Mhz.
The maximum that you will get is something within 400Mbps +/-.
And this is under the conditions that: 1. No one else will load your wifi, and the network as a whole. 2. The air is quite free and there is no interference.
3. Client must support mimo 2x2.
1300 declared on this router is because it supposedly has 3 radio modules (433Mbps * 3).
Well, again, the client device must also have three transceivers to implement past 3x3, and this, in theory, will be something around 600Mbps under the same conditions as described above.
