Hello everyone,
I am tested my project to building capsman server with caps so after finished all config and caps worked as well and lock capsman key with caps and its all worked as good,
I saw the problem when tested the signal i believe caps signal maybe the weakest signal in a broadcast "cap" when compared to the usual wireless from the same device "cap" so I used the cap RB "951 2n" And the Capsman server RB "2011 uias-2hnd -in" , And I used channel 1 frequency "2412" and TX power (-12), control channel width (20 Mhz) , Band (2ghz-g/n) channel 6 frequency " 2437" and TX power (-12), control channel width (20 Mhz) , Band (2ghz-g/n),
All devices upgrade to last version (6.46.5),
I saw the wireless interface of the same device "cap" without capsman i think the best covering distance is much more farther distances, Do anyone have tips to solve my problem?
Or is there anyone who has encountered the same problem!
Any advice?
Thank you

Any Advice

The signal strength will be the same as long as your configuration is correct....

The signal strength will be the same as long as your configuration is correct....

I am need to active capsman inside of building so whats the TX power should i set in capsman"channels configuration" because the signal strength depend on TX power?

You don't need to put anything in there, the max allowed is used by default.

If under Capsman -> Configurations -> Wireless you did set your Country (as you should) then the Tx Power will be the maximum allowed for you Country...
Only in case you want to lower the Tx Power you do use the Tx Power paramater field...

Which one you mean that?
My tested putting the TX power in channel of capsman server = 20 its good one the signal strength best of when using -10 for example!

In my cause my country Not Found with list, So i selected the Installation "indoor" And if set in channels of capsman I think if set to +20 maybe good, And if set empty maybe not good because signal is reduced, How i know the Maximum of TX power of mikrotik devices?

Your question is already answered...
If you leave the Tx Power empty, the MAX allowed by interface is used...!
However, you must use the Tx Power allowed in your Country... That is why we select the Country...

In my cause my country Not Found with list, So i selected the Installation "indoor"

Those two (country and installation type) are complementary, meaning that installation type does not work at all without country being specified. I guess when running your AP without CAPsMAN your obvious choice was "no_country_set". That setting (while illegal in many parts of the world) does allow you to use whatever frequencies and TX power your hardware is capable of. This option, however, is not available for CAPsMAN, and so when no country is specified CAPsMAN will enforce a rather conservative limitations. The best thing you can do is to specify some other country whose regulations are the same or very close to what's allowed in your own country.

Therefore, I did not know what is the correct value chosen because my country is not in the list, and now I will leave TX power it blank to work MAX allowed by interface as per your note ,
Whats the true select if i need to enable those "1 and 2" ?
Extension channel
Control channel width

Set control channel width to 20Mhz and extention channel either disabled, in case you only want to use 20Mhz as channel width, or Ce, eC, XX in case you want to support 40 Mhz channel width as well...

Set control channel width to 20Mhz and extention channel either disabled, in case you only want to use 20Mhz as channel width, or Ce, eC, XX in case you want to support 40 Mhz channel width as well...

Thank you, After tested when i selected the 40 Mhz and tried Ce, eC, XX but in log show failed to select and tried to change the frequency to 2462 or 2457 the same not worked!, Maybe working on 20Mhz so my cap its RB 951 2n , And the CapSman RB 2011 Uias 2h...

I am tried to set "no_country_set" and "Indoor" but the same Signal strength, And tried to select country maybe Close to my country the same, I tried without set anythink and empty and in channels of capsman the TX power empty maybe It could be better, Or set the TX power equal 17 and without in configuration that mean no "country and indoor" could be better also.

Be carefull with the frequencies. The selected channels are 20 MHz wide, the frequency slots are 5 MHz wide. Normally you use channel 1, 6 or 11 (2412,2437,2462).for no interference.
With Ce you use double the number of 5 MHz slots, so 2412 will use 2404-2408-2412-2417-2422 for C, and 2427,2432,2437,2442,2447 for e, and that's OK.
2462 Ce will be out of band, because the 20 Mhz e band is above the 20 Mhz C band at 2462. Even "2457 Ce" will not fit in the 2.4 GHz band. (European (ETSI) countries are allowed up to channel 13, but even that's not enough. No_country is limited to channel 11). 2412 eC is not possible for the same reason.

edit: ooops 2402-2407-2412-2417-2422 for channel 1 802.11b (22 MHz wide), not 2404-2408 ... (txs Zacharias)

TX power is normally given in positive numbers, but you know that already.
20 dBm = 100mW (milliwatt)
10 dBm= 10 mW
1 dBm = 1 mW
-10 dBm = 0.1 mW or 100 µW (microwatt)

2404-2408-2412-2417-2422 for C

It is 2402-2407-2412 ...etc...

2404-2408-2412-2417-2422 for C

Yes 5 MHz delta. Counting without multiple choice answers . Confused with 5 GHz channel delta

Thank you for all your information,
Normally I am used channel 1, 6 or 11 (2412,2437,2462), My notes here if have for example 30 Ap as Caps. Is it permissible to re-use the frequency channel 1, 6 or 11 (2412,2437,2462) distribution for the same floor? without interference or confusion and you can see below the example of distribution "Caps", The diagram is simple, illustrative :

My country Not available with countries so i tested to selected "no_country_set" and selected "indoor" but the same Signal strength, In this case i go to tried in Channel in capsman In order to write an appropriate value by TX power and tried equal 17 by normal maybe increase to 20, Can we say the signal got better but howerver how i know the routerboard how max. TX power can be working before damage the device? Or if i need to know How TX power it is determin to cover a specific area so that we distribute the rest of the devices "caps" in order to cover the spaces correctly?

You are at the holy grail of 2.4 GHZ wifi deployment. Many have tried and studied this deeply. There are numerous MUM presentations on this. But this is not a Mikrotik issue, it is the basics of 802.11 design and standard.

And those basics are good, bad and ugly. And they will frustrate and disappoint you (like anyone else in this wifi realm)

They are good because they deliver a wifi that always works, by slowing down until it works. There are slower speeds with lesser signal that goes further distance. And it goes very low, so the coverage is great. The whole design is based on a very polite rule, " only one talks at a time" (co-channel interference)

They are bad, because the usefull range for a decent speed is till -72 dB (see the sensitiviry of the hAP specs). The waiting for your turn goes down till a level of -96 dBm. So the usefull area around the AP is much smaller than the "wait your turn" area. Early on this was no problem, few AP's , low speed requirements. Now we have many AP's and need speed. The speed-span has risen from 1 to 11 Mbps to 6 to 300 Mbps. Those high speeds requiring higher signal levels (minimum -61 dBm) .

The ugly. Anyone in the lower signal range (-72dBm till -96dBm), can still communicate, but they talk slower, s l o w e r and s l o w e r . Worse yet they don't get the same share of time to talk , they get their turn to talk. And that 6 Mbps guy, takes 50 times more time to do its say. (If you still enable b mode, its 300 times slower). So the fast guy only gets 2% of the time to communicate, the slow one gets 98% of the time, giving them equal low speed.

The problem with 802.11 2.4 GHz is that the difference between usefull range and co-channel interference is too big.
In an open field, with a transmitter at 20 dBm, a receiver at 8 meter will typically receive -60 dBm.
In open field the signal drops 6 dB for double the distance.
4m= -54dBm
2m= -48 dBm
1m= -42dBm
0.5m= -36 dBm

16m= -66dBm
32m= -72dBm (the usefull speedy range)
64m= -78dBm
128m= -84dBm (stops usefull working)
256m= -90 dBm
512m= -96dBm (end of co-channel interference)

The ugliest part, are the cheaters that pump up the TX power above legal limits and add a strong antenna without compensating. 18 dBm more, 8 times the distance = 4 km disturbance.

For your channel reuse, which is a very good idea, please read this, and understand why walls might save the idea.: http://divdyn.com/docs/2.4-GHz-is-Dead-v1.00.pdf
