[ubuntu] Samsung Laptop wireless stops connecting to access point after update

view story

http://ubuntuforums.org – I have a Samsung Chronos laptop... I had just installed the 12.04 Ubuntu distro onto the laptop and connected to a wireless access point (note it is an apple AP). It worked fine. After running several days my distro did an update and afterwards the wireless seems to be working but it can neither find, nor connect back to the same access point. This AP is NOT hidden and yes I have tried to manually connect, but it won't let me. It appears from all I can tell that the wireless card is running and sees other APs, but not the previous one. I also had this working on my home AP (not an ap (Hardware)
