tx/rx signal strength is -89 -92 (Please help )

RouterOS Wireless Networking

Guy we have big problems. The second week we are steel not able to make work our RB532 routers .Porblem that Omnidirectional antenna not working in one kilometer.I tryed to direct routers each other with directional antenna in one kilometer. The Result is terrible .Please take a moment and look at the ping times. Somebody must know what is happening.

From directional client router I tryed to ping directional main router.

PLEASE HELP !!!

tx/rx signal strength is -89 -92 is very week you need beter signal to work, check cable, antena, card. You can try to change data rate use a fixed data rate. Select posible 9Mbps or 12Mbps or lower try it work beter but for 1km signal is very week.
I have link 2km with signal -72 /-72 fixed data rate to 36Mbps very low ping and transfer rate TCP 16Mbps in bandwitch test.

3

I already tryed to lower data rates to 12 mbps. But It is not affected.
What is rong with this routers I don’t know ?

Why omnidirectional antenna not working ? Where is our mistake ?
Even with directional antenna we got very high ping times .
:unamused:

4

By the way which cable you mean ?

5

Cable between miniPCI card and antena.
You can try to change antena a or antena b and watch the signal.
Please write what equipment your are using cable, antena, board. Then someone on forum can help you.

6

I suggest, don’t change settings, that you don’t understand.
Use default-settings for wireless interface configuration.
-Run ‘/system reset’,
-Enable wireless interface,
-set ssid, band frequency.
Connect antenna to the correct wireless card connector.
Than everything should work fine.

7

You need to tell us more about your setup if we are going to be able to help you… just posting ping times and yelling help doesn’t accomplice much.

Start by giving you hardware setup, start at one card and described every single part that is in the path until we reach the next card… including the cards themself

Also, have you done a link path budget? That is the FIRST thing to do when you are going to set up a new link… even before ordering the gear!

Best regards

hi, friend

waoooooo :astonished: :astonished:
my Apple slow slow connection…cos too many PINGING REPORT

nothing way to make help, [maybe your RouterOS and Wireless Confuse], better you can start from begining by reseting your routerOS and make sure after reset, IP address, SSID, Band, Frequency [AP and Client must be same SSID, Band, Freq]. Don’t make change if your are not understand, leave everything config as default is better. here our wireless without LOS around 4,5km work fine.

You may be to high with the omni. It could be shooting over your customers.
But, then again if you can’t get it with two directional antennas I would say that you need to try changing the channels and if thats a bust then try the 5 and 10 mhz channels. (Only if you are using Mikrotik at both ends.)
Try the first link to see if you are in line with the other antennas your trying to hit.

http://www.wisp-router.com/calculators/fresnel.php
http://www.wisp-router.com/calculators/simple_som.php

There are other calculators but I have to plug Eje any chance I get. LOL

Please answer some of these questions so we can try to help you the best that we can.

Can you tell us what antennas you are using, omni and directional(dbi, brand, model# )?

What miniPCI radios are you using in the AP and CPE?

How high is the AP antenna?

How high is the CPE antenna?

Do you have full line of sight?

Is there anything blocking the line of sight?

Have you ran the Frequency Usage tester in MT to see if there are cleaner channels to use?

10

to sergejs:

I did it almost one hundred times.It didn’t help us.



Sorry guys I can’t unswer all of you.But I ll try to describe everything as I can.
And thank you for your support.


I am going to write everything again detailly.
We have four RB532 Wireless routers.Two of them is directional router other two is omnidirectional router.

All antennas are in dbi mode.

wireless card R52
FCC ID:TVR52


2.4 (18 dbi mode)

there is no any obstacle between routers.

the last test has been between directional and omnidirectional routers in 50 meters.
From the Two main routers we got the same signal level.Also from the client side we took both directional routers for test .But the
same signal level.Everything terrible .It is my first Wireless MAN project.
But I didn’t expected everything will be so terrible.

The same signal level we got from directional antennas in distance 600 meters.Unfortunatelly in such distance we can’t get signal
from omnidirectional antenna.


Please look at the website provided bellow for locatiot one the main routers and signal levels:

I guess you have R52 wireless card (You have to connect pigtail to ‘outside’ secondary connector of the card).

Try to use another frequency for the AP (use ‘snooper’ to find another possibly less overloaded channel).

13

Signal level is very low, check cable from antena to router and check antena. Check every connector.
Try to change antena a or antena b and check signal.
On picture signal is very very week. Your problem is signal you must have better signal and then everthing work.

to sergejs;

I tired every time to change inside motherboard pigtail place (main and aux) .I also cganged from configruration mode antenna mode to B and to A.

And also it is not so simple just to direct dicectional router to omnidirectional router and to get signal.Sometimes we can’t get signal .

to npero;

What you mean when you saing ,check the cable. What must I do ? I think everyting ok.

15

to Jober;

Our director not allowed to use 5 or 10 ghz .In our country this frequency licenzed and most compnies using it.

16

Rauf,
once again don’t change configuration you don’t understand.
For ‘antenna-mode=ant-b’ use aux connector.
Are you able to get normal signal, when routers are placed near to each other ?

17

He didn’t write to use 5 or 10 Ghz frequencies, but 5 or 10 MHz channel bandwidth!

Best regards,
Christian Meis

to cmit ; You are right !



to sergejs;

Router each other working ; - 64 - 68 signal strengh

But when I again got router a way for 50 meters signal level a gain was
-90 -96 range.

I also removed extention cabel from Antenna.I connect it without it.

I again want to note on our area there area some d-link routers for indoor. Ther area also visble outdoor. Is it possible that interference to Mikrotik routers.

Please some suggestion.

It is not possible that you don’t a have suggestion.

Guys where area you all ?

King Regards

  1. First check that you use correct antenna connector (if you get bad signal over 50 m, it means annena connected to the wrong connector).
    for antenna-mode=ant-b aux (secondary).

  2. Check previous posts above, I said try to change a channel (snooper feature will show network load over all channels on used band).

2.4ghz u need signal better than -70, and -50 is ideal
this is different from 5ghz signal strength -50 up to -80 still okay to pass through 6mbps data
