Luke, thank you for reporting this and helping make Ubuntu better. The
next step is to perform a kernel bisect to identify the offending
commit. Could you please do so following
https://wiki.ubuntu.com/Kernel/KernelBisection ?
** Description changed:
Binary package hint: linux-image-3.0-0-generic-pae
Beginning with the installation of the version 3.0 kernels, network-
manager-gnome's nm-applet began repeatedly connecting and disconnecting
- from wireless networks.The behavior is similar to what would be observed
- if all wireless connections were barely strong enough to connect and too
- weak to stay connected. Network-manager gnome's nm-applet still reports
- correct signal strengh, but fails to stay connected. This occurs without
- regard for rather Unity or gnome-shell is running at the time. At first
- I blamed network-manager-gnome, only to find that it hadn't changes, nor
- had the other networking programs. Suspecting new kernel drivers, I
- decided to try a reboot with the previous kernel, and was back online.
+ from wireless networks. Network-manager gnome's nm-applet still reports
+ correct signal strength, but fails to stay connected. This occurs in
+ both Unity and gnome-shell.
- Booting from kernel 2.6.39-3-generic-pae instead of a 3.0 kernel stops
- the problem and wireless networks then remain connected and behave
- normally. Either the wireless driver in the kernel has a problem or it's
- interface with network-manager-gnome changed enough to require changes
- in that package, no idea which. No problems with the wired connections
- used by my second video-editing computer downtown, both video editors
- being AMD Phenom II x4/785 chipset machines with 4GB ram, hence the pae
- kernels used all all copies of my OS install.
+ This occurs on my Acer Aspire 1 netbook with the Intel Atom N450 and
associated chipset.
+ This bug is still present with linux-image-3.0-1-generic-pae.
- This occurs on my Acer Aspire 1 netbook with the Intel Atom N450 and
- associated chipset. The pae kernels are used because this machine
- downloads all packages bound for the offline video editing comp0uter
- with 4GB of ram.
+ WORKAROUND: Booting from kernel 2.6.39-3-generic-pae.
+ WORKAROUND: With Linux 3.2.0-17 or 3.2.0-18, and with acer-wmi blacklisted.

- This bug is still present with linux-image-3.0-1-generic-pae, just tested it
today
