I saw one disconnect due to reason 4 (disassociation due to inactivity). There were many changes in the rtl8192cu driver for kernel 3.11, and you need to run it, or a backports version of the wireless code. Your 3.8.0 kernel is too old. I have been running rtl8192cu for the past 24 hours without a permanent disconnect. Under NetworkManager, I see some reason 7 deauthentications, but running under ifup, there have been no disassociations or deauthentications in over 6 hours. I am using openSUSE KDE. There may be a problem with the Ubuntu user code as it seems to operate differently. Larry
