I'm experiencing a similar bug after I did upgrade to 11.10 from 11.04 with `do-release-upgrade`. None of my connection profiles are missing, but Network Manager doesn't automatically connect to my Wifi network even though it worked perfectly in all previous versions of Ubuntu. Also, if I run "sudo iwlist scan" network manager connects almost instantly.
