Mikrotik radio bridge, frame loss, clients only ip cameras?

Question

WiFi

Good evening.
There is a problem with streaming from ip cameras.
Bridge on RBSXTG-2HnD (AP) and SXTsq Lite2 (clients, 2 pcs.)
Clients only ip cameras, no other devices, traffic only for return.
From one point 6 Mbps, from the other about 20 Mbps.
The distance from the AP is 300 m.
The problem is that not all packets (frame loss) reach the main stream. As I understand it, this is due to the bitrate (on the additional stream it is quite low and there are no problems with it). In the main stream, the bitrate from the camera is 4-6 Mbps.
Protocol nv2 (on 802.11 the same problem)
Everything is ok with the fresnel zone, there are no obstacles. object in the field. From the radio of the neighbors, there is a link from the provider, the channels with it are different.
Actually how to get rid of frame loss? How to correctly set the priority on the return of traffic on microte (there is no rx on clients, only tx)? And does it make sense to change the default values ​​in Queues for the wireless interface?
Maybe there is some article or discussion on the forum on setting up a bridge with clients in the form of ip cameras?

If you need configs, I'll send all the screenshots, now there is no access to the points.
PS: Disabling AMSDU Limit or AMSDU Threshold may "fix" data transmission. I set both of these parameters to 0 and it became much more stable. The default was 8192, but in all the manuals that I came across they advise not to touch these parameters.

Answer 1

We need an ap layout with the distance to each client and the angle between them. Are the equipment properly connected to each other? What is the ccq on each device? Why did they kill amsdu (did you read the description of this setting?)?
But in general, most likely your cameras work on UDP and transferring to tcp will turn out to be the very magic crutch that you are looking for, instead of step-by-step setting up bridges according to the manual, of which there are hundreds.
