I created a question before: Wifi is fine on Ubuntu but very slow on window 7
And I found a solution by running this command:
sudo modprobe -r b44 b43 b43legacy ssb brcmsmac wl || sudo modprobe brcmsmac
But everytime I restart my computer, I must run it again. If not, other computer in my network will have slow connection. And my questions are:
wl mode is the reason?
2. How to set permanently this configuration?
Thank for your attention :-)
