I have differences between 2 EAPs 610  with different Versions

V2 (1.1.7 Build 20240313 Rel. 74955)

V3 (1.4.4 Build 20240312 Rel. 38091)

the V2 has better coverage. Placing it in the same position and scanning the network from a network scanner I can see differences of 20dbm... Is this possible? ia have reset the units and put one by one in the same position using the same settings (channel).

Whats is really the difference between the two models?

Thanks.

Pablo.
