Hmm, I don't know it coz I am not a network security guru. One of my 
friends told me to hide the SSID to make my wireless AP safer since 
hackers can not see it. It must be an illusion,
 isn't it? Can you tell me why?

BTW, I try again in the weekend to broadcast my SSID, it only works when 
I didn't set any security mechanisms(WEP or WPA). When I set 128-bit WEP 
again, the wireless failed. Should I try iwconfig something manually? I 
am running Fedora 9 live from a 4GB USB stick.
