Tim, I know that hide SSID is far away from be efficient against 
attacks. This is not what I intend. I have problems in some clients with 
specific WLAN cards. The software from the card associates to the SSID 
with stronger SNR, even if I place the correct SSID in the 
configuration. But only happens if the SSID is open. I have 3 different 
wireless networks, and if the client of one of them associates with the 
wrong AP, his connection don't work.

So, to hide the SSID would be important to me...

Any suggestion?

Thanks!
Denilson
