Vincent,
If you are still running kernel 3.8, then there is nothing I can do. I made a
lot of changes that are included in the 3.11 kernel, and they fix a lot of
things, but they could not be backported to 3.8.
It turns out that ping also made no difference here. Since my last reboot, my
RTL8192CU device has been connected for 4 hours with no disconnections.
