We put two CURWB APs on a single desk and connected them with MESH.

Then we connected a PC to the DC injector and measured the network with PC to PC and iperf.

But we are not satisfied with the speed.

I need some advice to improve the speed.

What speed are you getting?
What firmware are the two APs on?
How far (distance-wise) are the two APs situation from each other?

There is an APs on my desk. The distance to the AP is within 1 meter.

The speed is sometimes 100 Mbps and on average 200 Mbps.

The distance between the APs with a Tx power of 20 dBm is too short, which can cause overmodulation. Set the Tx power to the minimum for testing purposes.
Ensure that the antenna gain is configured correctly (7 dBi for 5 GHz).
Make sure the distance between antennas connected to the same AP is at least 20 cm
