Note that I had a problem with the same symptom, and in the end, what solved it was killing wpa_supplicant, as suggested in this bug comment: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1294044/comments/9

For a while, the connection will just die, then it will be detected and NetworkManager will re-authenticate and re-associate. In Lucid Lynx, this problem is now much more frequent (often exactly every two or four minutes) and now Ubuntu does not report that the connection has dropped. Instead, it re-associates in the background, eventually connecting to the access point again, all behind the scenes. Thus, the only thing that has changed, aside from the greater frequency, is that Ubuntu now doesn't report that it has dropped the connection, which seems deceptive from previous versions. This may be the same bug as bug 429035, but my dmesg output is a bit different. This problem occurs primarily on a WPA2 Enterprise network, but the problem has occurred on other network security configurations as well. dmesg output after many instances of disconnects: [
