Public bug reported:
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.
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. The pae kernels are used because this machine
downloads all packages bound for the offline video editing comp0uter
with 4GB of ram.
This bug is still present with linux-image-3.0-1-generic-pae, just tested it
today
