Raw message 

Norberto,
thank you for answer.
I was using roaming between close APs all pluged at Grase LAN side. 
Never think that would be a problem in remote scenario.
Well, today I realized the truth.
As said before, it is not a problem if client temporary loose connection 
when walking from one AP to another when two APs are out of distance 
range between.

Need to find a solution now.
