How and where did you upgrade the kernel and did you include linux-image-extras?

BCM4313 needs the firmware for the respective module:

wget http://media.cdn.ubuntu-de.org/forum/attachments/39/45/5007272-Broadcom_Firmware_fae7121.tar.gz
sudo tar xvf 5007272-Broadcom_Firmware_fae7121.tar.gz -C /lib/firmware

I wasn't aware that brcmsmac required firmware.

I update my kernel from upubuntu.com, do you know the latest linux kernel that works with b4313 ?

As far as i know, every kernel since 3.0.xx works fine. Let's identify your device first:

lspci -nnd 14e4:

And let's look at some diagnostics:

dmesg | grep wlan

It's strange, i reinstalled my ubuntu, and do what i do before. And then, it's working with the old driver

I'll take it! I'm glad it's working by whatever method. Have fun and post back if we can help you again.
