2 SXT ppp - one way signal is bad

RouterOS Wireless Networking
1

Hello.

I recently changed ubnt nanos to mikrotiks SXT on one link 'cause I need more bandwidth.
Ubnt worked perfectly but with STX I got a problem.

One way signal is worse then the other. 98% and 25-33% respectively.
About 64 and 67 dBm requency signal strenth. Clear LOS. About 600 m distance.

I tried to change frequency several times - no result.

Any suggestions ?

  1. Install RouterOS 6.7 on both SXT
  2. in 1st SXT in terminal digit: /interface wireless export compact file=device1
  3. Put the file device1.rsc from SXT in PC
  4. in 2st SXT in terminal digit: /interface wireless export compact file=device2
  5. Put the file device2.rsc from SXT in PC
  6. open each file with notepad, or similar, remove sensible data (password), and post both code in the forum.
  7. Wait for users help (also my).

Thank you this is what I needed.
One thing though
It seems that I always loose all contact with the units as soon as the bridge comes up, is that avidable ?
