I notify the problem to the maintainer of the kernel, larry finger and he said the following:
"There are a lot of changes in this driver in the wireless-testing tree that will not be in the mainline tree until 3.14. Please generate a kernel from that repo."
actually there were changes affecting the kernel wifi drivers, but I'm currently be using the most current kernel that appears on the website of ubuntu mainline kernel.
the problem persists. this problem appeared in the kernel v.3.9
