    And, as you suggest before, it doesn't work when I restart the computer.

    Let's get the driver fixed first:
    Code:
    sudo su
    apt-get remove --purge brcmwl-kernel-source
    echo brcmsmac >> /etc/modules
    exit
    Now reboot and let me have a report.

    I've done commands that you told me to reactivate wifi after doing last commands and reboot, but the signal is still quite low. In "Connection informations", the speed indicated is 28Mb/s at 40cm of the router.

    I am not aware of any method in the driver to affect signal strength. You might look around in the router's configuration pages. Make sure if there is a transmit power setting, that it's at the maximum. Experiment with channels. Most routers are set, by default, at channel 6. I have the best luck with channel 11. Finally, many routers have a selection for antennae; left, right, both or automatic. Experiment with each.

    Re: Can't solve Broadcom BCM4313 wireless problem on Ubuntu 12.04

    Thank you chili555, but nothing changes. On other forums, it seems that installing the driver from the Broadcom website (http://www.broadcom.com/support/802.11/linux_sta.php) it works. I tried, following the Readme instructions, but I have a problem when I try to do the make function. This is what happens :
    Code:
    baptiste@baptiste-HP-Pavilion-dm1-Notebook-PC:~/drivers/hybrid_wl$ sudo make
    KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`
    make[1]: entrant dans le répertoire « /usr/src/linux-headers-3.2.0-31-generic-pae »
    Wireless Extension is the only possible API for this kernel version
    Using Wireless Extension API

    make[1]: quittant le répertoire « /usr/src/linux-headers-3.2.0-31-generic-pae »
    make: *** [all] Erreur 2
    Do you know how I can solve this problem ?

    Thank you !

    Thank you for the link, it works now, with the full signal !!
    However, I have to do that in the terminal at each boot :
    Code:
    baptiste@baptiste-HP-Pavilion-dm1-Notebook-PC:~$ sudo modprobe lib80211
    [sudo] password for baptiste: 
    baptiste@baptiste-HP-Pavilion-dm1-Notebook-PC:~$ sudo modprobe cfg80211
    baptiste@baptiste-HP-Pavilion-dm1-Notebook-PC:~$ sudo rfkill unblock all
    baptiste@baptiste-HP-Pavilion-dm1-Notebook-PC:~$ sudo rmmod brcmsmac
    baptiste@baptiste-HP-Pavilion-dm1-Notebook-PC:~$ cd drivers/hybrid_wl/
    baptiste@baptiste-HP-Pavilion-dm1-Notebook-PC:~/drivers/hybrid_wl$ sudo insmod wl.ko
    Do you know what I can do ?

    Thank you again !!

    Re: Can't solve Broadcom BCM4313 wireless problem on Ubuntu 12.04

    Please try just this and tell me the result. We'll fix it easily:
    Code:
    sudo modprobe -r brcmsmac
    sudo modprobe wl

    I've just tried this after rebooting, but nothing happens. It just shows me "Network disconnected"

    Re: Can't solve Broadcom BCM4313 wireless problem on Ubuntu 12.04

    Please do:
    Code:
    sudo gedit /etc/modules
    Where brcmsmac appears, remove it and replace it with wl. Proofread, save and close gedit. Now do:
    Code:
    sudo gedit /etc/modprobe.d/blacklist.conf
    Is there any mention of wl in there? If so, remove it. Add:
    Code:
    blacklist brcmsmac
    Proofread, save and close gedit.

    Reboot. Now check to see which module is and isn't loaded:
    Code:
    lsmod | grep -e brcmsmac -e wl
    Hopefully wl and its dependent lib80211 only are loaded. Check rfkill:
    Code:
    rfkill list all
    Any improvement?
