    Broadcom bcm43228 disconnect/slow

    Hi,

    My laptop (HP probook 6475b) has a Broadcom bcm43228 chip. The wireless does work, but it keeps disconnecting/slowing down all the time when I'm running Ubuntu. When working in Windows everything is faster and stable.

    I installed the kernel source thingy, the STA driver, and tried a lot of the other suggestions a quick google brings up. Did anyone else experience similar connectivity problems? If someone has advice it would be greatly appreciated

    cheers,
    Bram

    I'm always on the same campus network. Could it be that I somehow badly configured this specific network in Ubuntu and that it is not a driver thing? I'm running Ubuntu 12.10 Btw

    Hi, copy and paste this command in the terminal (ctrl+alt+t) please:
    Code:
    wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script
    It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
    Thanks

    Thanks Wild Man,

    I ran the script and attached the result here.

    (P.S. I had to put it in an archive since the max text file size I could upload here was 19.5kb(

    Hi, we are limited in what we can try because of the driver that you have to use with this card.

    Please try:
    Code:
    sudo apt-get install linux-headers-generic
    sudo apt-get install --reinstall bcmwl-kernel-source
    Reboot

    I believe the issue is because of the encryption being used and because there are so many networks in your area that network manager keeps trying to get to each one every few seconds.

    Also the signal strength and quality of link is not very good.
    Thanks
