The power of signal is good. After the time my client change AP and choose che other AP (and the signal became less).
i define this feature with roaming.
This is a general problem (not only my client e AP).
i TRIED to power off the AP1 , but the roaming there is always from other AP.
LATELY , there are more ROGUE AP in this area. There is a solution for to exclude this ROGUE AP. I think that the clients view this rogue AP with excellent signal and try to connect to it.In this operation the client disconnect him with the AP.
