hey guys i have a wireless link ptp by LHG XL Ax i did it in more disances about 16KM but now in 4KM i have a problem about connection, the signal is great about -51, -55, but the connection dropped?!
Has anyone ever had this problem?
You.
This is just a riddle.
How many questions do we need to ask before we know what you know
and how your devices are configured, the exact model, and the exact RouterOS and RouterBOOT versions?
Did you use a professional spectrum analyzer to check if the frequency you're using is free of interference?
Did you use a professional wattmeter to verify that the expected power was actually being radiated?
How many questions are needed? And that's another question.
For me the solution is: You have not mounted the antennas correctly in the "right position".
Both places are so noisy, freq range is 5170-5875, channel width is 20/40mhz destination is 7km and the country is Superchannel , we just have one freq free it was 5660 but when i set it doesnt work also
1 freq. free = 20MHz
5660 free...
So, why 20/40 if only "space" for 20MHz?
Well, pardon the pun, but I guessed right... 
You mounted antenna not on right position... in that place is full of interference!
A little help:
If someone has always helped you and inspired trust, and you've relied on them,
well,
in case they betray you, trust in someone who has the gift of omnipresence...
Look up what omnipresence synonyms have... (on incorrect English)
Then it's up to you to do the math.
Do you prefer to pay less and hope to find a way to make the device work,
or pay more and significantly increase the certainty that the device will work?
(there are absolute certainly only on taxes and death)
its not about paying some money its about work , i could pay more but for something to work, i have tested 20mhz also but reasult was same everything looks great, but the bandwidth is terrible .
i hope MikroTik makes another update to solve this issue .
@rextended you write like a politician talks. Do you want to make OP freak out?
Sorry, but what is there to fix? If the spectrum is so noisy, software can't fix that.
thank you for replay , but LHG XL AC (the older version) was working at least at this 7km , Mikrotik was always great im reseller for about 12 years i have a lot of returned AX devices for this issue .
my config list is below:
SSID : B1
Sec prof: wpsk2
freq : 54560-5850 MHz
channel width : 20/40mhz (i have tested 20mhz also) 5AX
if possible i could upload all configuration
Did you configure distance property in the wifi settings? Default settings only apply for 2km according to manual.
yes , it was 6.8km and i have set 7km in distance
Exactly...

Do not use WinBox 3 on 7.2x, produce this.
Remove that config.
Paste this on terminal (also on WinBox 3... if needed):
/int wifi
set [find] !interworking.realms-raw
/int wifi configuration
set [find] !interworking.realms-raw
EDIT:
frequency can not go arbitrarly from 5170 to 5895:
This is a problem (still using Winbox 3?):
interworking.realms-raw=""
At least unset this value.
Why no fixed channel?
this place is so noisy so i didnt fix channel , it could be a problem also?
@normis clearly answered your question...
Aside from that configuration issue...
Sorry, but what is there to fix? If the spectrum is so noisy, software can't fix that.
And if you see 5660 only free, with 20MHz, why do you try to use any frequencies at 20/40mhz?
We're going in a loop with the same questions already asked.
Buy a 60GHz product from another vendor[1], and God willing, that will be fine.
Since MikroTik stop development of 60GHz long-range devices (2+ Km) ↩︎
mimosa c6x solved the problem , but its long time we are waiting for mikrotik PtP devices we missed some product like DynaDish...
Since MikroTik has switched to using only default drivers,
without developing custom protocols like everyone else,
it has automatically cut itself off from any outdoor development.
Ax performance in the lab is fantastic, but outside there's the real world...
Whatever happens, MikroTik as a router is irreplaceable in a customer's home...
Even if there's a CPE from another manufacturer outside,
the customer's home will still have the MikroTik device.
I'm not going to change them...
Hello, try to remove parameter interworking.realms-raw="" , It shows up when you are configuring wifi from Winbox 3...
/interface wifi set [find] !interworking.realms-raw
/interface wifi configuration set [find] !interworking.realms-raw
Already posted twice, and by two users. What was the point of the third?
