I made several test changing the configuration of the AP (I am not able to change de wlan profile of the machines), but none of them was successfull.
Then I made last two successful tests:
The firts thing I tried (as a suggestion by googling and TAC) was to use encryption AES (just AES, NOT AES+TKIP) and it worked good. I didnt get desconnected and anything, but the issue was that the AP is going to work with clients that have to use TKIP becuase the wlan profile on the machine cant be changed that easily for different reasons.
The last one was to go to another room where there is very few wlan signal noise around (where I was originaly testing the AP, there are a lot of SSIDs flying around).
And that was it, using TKIP on this new room work just perfect.
