    Can't solve Broadcom BCM4313 wireless problem on Ubuntu 12.04

    Hello,

    I've just installed Ubuntu 12.04 32bit on my HP dm1, and the wireless doesn't work. The wireless card is the Broadcom BCM4313. I tried many solutions from many forums, but nothing works. Can someone help me to solve this problem ?

    Thanks a lot !

    The first rfkill list is done without pushing the wifi button and the second one, after pushing it.

    Thank you !

    Please do:
    Code:
    sudo modprobe -r hp-wmi
    sudo rfkill unblock all
    rfkill list all
    Any improvement? If so, we'll write a file and make it persistent.

    Now please try an additional step:
    Code:
    sudo modprobe -r wl
    sudo modprobe brcmsmac
    sudo rfkill unblock all
    rfkill list all

    Thanks a lot ! Pushing the button, it works !
    However, even if I'm closed to the wifi router, the signal is very low. Do you know how I can solve this problem ?
