Ha Ha that's funny!

Anyway. if you have UBNT as CPE, monitor their signal level and noise floor to start with
PS: there would be many many reason. you want to ask, what has changed?

I guess you need to elaboratemore on what do you meen by disconnects?? Like really disconencting to the wifi signal meaning they are kick out and would need to reconnect? Or is the signal streng bad? Or maybe they are connected to wifi and have a good signal strength but they cant get internet?

-68,-74 are not good signals, what is CPE device's distance, also good to know noise floor, are all devices disconnecting or just CPEs with signal >-65

what about -63s? All the devices are with in 2km distances. Most of all devices are disconnected which are <-65 as well.

In your log I can see only CPEs with bad signals disconnecting.
LHG->MantBox15 2km >-63 signal dude probably LOS is not so good, theoretical signal level should be in range of -50, -58
if you are sure you have good LOS maybe your mantBox angle is not adjust well
MantBox is 120 degree (Horizontal Elevation) sector antenna you should be aware of that, also you can try adjusting little up and down (Vertical Elevation) see if you have any signal improvement
You are using 802.11 protocol theoretically CPEs with bad signals may be the "trigger" to this problem with nv2,airmax protocols (TDMA) you don't have that.
Thats why connecting UBQ and Mikrotik CPEs on same AP is not wrong but bad idea.

We have tried almost everything that you said its not with only some customer its with most of all my wireless customers.

Dude just told you, your clients signal level is very very bad for 2km distance.

As others have pointed your signal levels are terribly low for such short distances. This means that your links are misaligned, not to mention also potentially riddled with LOS, fresnel, intererference and frequency problems.

If you don't take care to make a good job at the physical layer, then nothing you do after that is going to help you much.

Have you got any photos or video that shows best way to align mANT 19s.
