one CM9 , with direct dish antenaa.
antenna make link on 3km.
on this cm9 I have connect one more user, on 60 degree from left on 1km
link have -50 tx/rx
user have -56 tx/rx
link have 4/4mbps 800/800pps , ping are 1-5ms
when user have 1/1mbps 100/100pps … ping on link go to 1-150ms
with 1mbps/256kbps ping are 1-30ms
btw, when link have 8/8mbps , 1500/1500pps, ping are 1-5ms
only when this user have 1mbps traffic , we have problem.
I think maybe degree of user can cause this , but signal are ok …
, what can cause this problem?
AP side have default seting,
link have defult seting and connect on 48-54mbps, ccq 88-100
user have set 6Mbps only (fix rate) , for support and basic
and have 6Mbps about 20ccq,
on AP side:
user are limit on 1mbps in queue
link is not limit, only user on the and of this link
mt(with queue for this user 1mbps) --------1km-------- user with (1mbps)

CCQ of 20 is your problem. For whatever reason you have a bad link - might be noise, self interference, bad los, etc
I think , CCQ (client connection quality), is only info of maximum bandwidth …
If I have -40dB , if I set bandwidth on 54mbps , CCQ will be 100, if I set on 6Mbps CCQ will be 20
if I need only 1mbps, I set user on 6Mbps, and CCQ are 20, … , this can’t be problem, but, I am not sure.
is this right for CCQ?

Not at all. CCQ has to do with the quality of the connection. A CCQ of 20 most likely barely works.
