I have some problem in my wireless link. The signal is strenght, CCQ RX is 98/100% and low CCQ in tx rates ( 37, 44%). I tried anything, change channel, modulation, etc. I need help

Thank you

Do you have more radios near by? It looks like interference to me.

There is some radios, but not in same channel. The frequency usage show me that don't have used channels.

It doesn't matter, interference can exist..

Don't forget that you're using a 40mhz channel which is more susceptible to interference.

Suppose that your receiver is located near another receiver on a similar channel - did you do your spectrum analysis at the client site?

Yes I did. I''ll try change to 20mhz channel. I think this really is interference.


thanks all

On both sides what other signal levels present when a frequency scan is done?

In other side there is no interference, because it is in the jungle, no radios, no wifi.

is it clear line of site as it can be water in a tree

Have you good Fresnel clearance on this link?

Yes.

Has this been resolved?

I have a similar problem; I would like to know what the issue was.

on AP and Station:
- what antenna do you use ? (gain)
- what are Tx Power? (default?)
- what rf-cable you use?
- how many km are the link?

Pull spectrum from the side that has the low rx ccq, if there are ANY signals over roughly -50db this will happen no matter what you do. To the best of my knowledge this is due to mikrotik and almost all other wifi based manufacturers using very wideband receivers with fairly poor selectivity, active filtering like cambiums 450i platform or a superheterodyne receiver would go a long way towards resolving this but that adds to the cost.

I had a pair of SXTs that were doing this and it drove me up the wall, it finally clicked and I moved the problematic SXT about 4 feet from its closest 5ghz neighbor and just like that 99-100% ccq on both sides.

If you look around you can find stuff that's similar to rf armor for the sxt units, it helps keep them isolated and also keeps their fairly dirty radiation pattern from impacting other devices.
