Is it possible to reduce the effect of "overlay" WI-FI signals from the two routers?

Problem. There are two points wi-fi. Are two feet away from each other. Both 2.4 Ghz. Through observation found that when you work two at the same time, the signal from one of them deteriorates as the distance and near. Often lost the connection or the speed is very slow.
Is it possible to reduce this effect, if not to push them from each other?
Tried to change channels to 6 one 11 the other - no effect.

Sad situation.

Of course, as it should be. Only the signal is not getting worse, deteriorating the ratio of signal/noise.

Is it possible to reduce this effect, if not to push them from each other?
It is theoretically possible, but extremely difficult and completely will not solve the problem.
Options - spread in frequency, moving one of the points on 5GHz, or by placing between them radioprotecao partition, or to choose the antenna to the radiation pattern minimally overlap.

Tried to change channels to 6 one 11 the other - no effect
. And where to take it?

So you can dilute spherical horses in a vacuum, but in a room where more people paleotragus, much worse.) - Benedict_Shiel commented on June 8th 19 at 17:16
Well I told you-it is theoretically possible.
But practically extremely difficult. - earl.Weissnat commented on June 8th 19 at 17:19
uh, on 2.4 GHz I see 3 non-overlapping channels. 1-6-11. - Noemy49 commented on June 8th 19 at 17:22
Actually , different channels, different frequency still, so this should help. 6 and 11 do not overlap with 20MHz band. - Guiseppe commented on June 8th 19 at 17:25
Not intersecting the channels not in principle.
All the channels intersect, just some less than others are more.

,
In fact, different channels, different frequency still, so this should help.
The channel is a small shift of frequency to hold the signal only within a given frequency it is impossible, therefore work on any channel interferes with another channel.

Therefore the diversity channels is only effective when the signal of a single point is fairly weak.
In this situation the points are close, so the effect of flow channels will not be absolutely.
Attempted transfer on the same channel will cause conflicts on the other, in the end, a long line - and as a consequence high pings and reduced speed.

And if you move the access point at a sufficient distance - then transfer on 6 and 11 channel practically do not interfere with each other.

So first of all you need to spread the points so that their coverage area as small as possible overlap, and secondly to post them on different channels. - earl.Weissnat commented on June 8th 19 at 17:28
You can still try the first and last channels to deliver. You can also remove the encryption, it's got a little speed increase. There is still MIMO. And the main method is to replace two router on one. - Alize_Moen commented on June 8th 19 at 17:31

Doesn't work, encryption does not increase the traffic, just more CPU of the router. And here the problem is clearly not in the performance of the processor.

There is still MIMO.
Nothing in this situation will not help.

Not too effective, though a bit can increase performance by minimizing collisions. - earl.Weissnat commented on June 8th 19 at 17:34
your one router ineffective? And how many routers effectively set at one point? Can be 5?

Why is MIMO help? Moreover, mimo can on clients to use. But even if you do not use, MIMO can enhance the snr in 2-8 times. However, still the speed is determined by aplicom, usually. But purely for the web or video/music will do.

Encryption requires very very very little data to establish connections, but still requires. So in case of emergency...

By the way, the beacon frequency can be reduced. - Alize_Moen commented on June 8th 19 at 17:37

At one point one is enough, more makes no sense.
Just one router will use the air completely, the two will share with each other - so two router at one point will work a little less efficiently than one.

Why is MIMO help?
Well, as far as I understand this problem is the congestion of the ether. MIMO to provide higher quality communication with the client, but ether is not appreciably relieve. And from the client depends. - earl.Weissnat commented on June 8th 19 at 17:40

If you have wifi n, and strip selected 40MHz, then you need to post frequency more than 6 and 11 channels, e.g. 1 and 11 channels, or switch to 20MHz band.
And even better to put some inSSIDer, and see what is happening in the air and choose the least loaded channels.
to choose the least loaded channels.

"Least loaded" does not mean that. The next "empty neighbors" channels would be great to score each other.

I do not propose to select the neighboring channels, on the contrary, if it comes to that. And in the same inSSIDer is very well presented visually overlaying adjacent channels... - earl.Weissnat commented on June 8th 19 at 17:21
feel free to ask , but can you imagine how does a receiving radio channel of the access point? Regardless of which channels are selected within the same range, the receiver is overloaded, leading to the inability to "hear" clients, if there is another transmitter. Because hardware tunable preselector (a bandpass filter) with a width in the channel at the receiver, but there is a diagram of the AGC, which adjusts to the strongest signal (from the neighboring access point, not from the weak of the client). So do not care what inSSIDer in this situation will show. - Noemy49 commented on June 8th 19 at 17:24
