    Ubuntu 12.04 32bit Lenovo s10 e Ideapad Cannot connect to wireless (BCM4312)

    Hi everyone,

    I am trying to connect to my home wireless network on a Lenovo s10 e Ideapad. I tried using the Broadcom STA drivers through jockey and bcmwl-kernel-source but had no luck. Installing b43-fwcutter and firmware-b43-lpphy-installer through terminal allowed me to connect but upon reboot the wireless just keeps attempting to connect and fails.

    If anyone can help, I will be very grateful.

    I will provide the following information in case it is useful :

    Re: Ubuntu 12.04 32bit Lenovo s10 e Ideapad Cannot connect to wireless (BCM4312)

    Hi, to calrify you said..
    "firmware-b43-lpphy-installer through terminal allowed me to connect but upon reboot the wireless just keeps attempting to connect and fails."
    so it looks like all was well untill you booted..is this correct?
    if so..please do...
    Code:
    sudo modprobe b43
    *IF it connects then do..
    Code:
    sudo su
    echo b43 >> /etc/modules
    exit
    this will load the module every time you boot.
    thanks.

    Hi Hadaka,

    Yes, it seemed to be working fine until I rebooted.

    I tried :

    sudo modprobe b43

    But it doesn't work.

    Thanks.

    Re: Ubuntu 12.04 32bit Lenovo s10 e Ideapad Cannot connect to wireless (BCM4312)

    Did this :

    Code:
    sudo apt-get remove --purge firmware-b43-lpphy-installer
    sudo modprobe -r b43
    rebooted, then did this :

    Code:
    sudo apt-get install linux-firmware-nonfree
    sudo modprobe b43
    Didn't work, just kept on trying to connect, fail, trying to connect again...

    So I rebooted again but still no luck.

    Ok after shutting down and booting, the wireless works but a wired connection has to be present during boot up.

    Otherwise during boot up, it says "Waiting for network configuration...Waiting for network configuration for 60 more seconds..."

    Then it boots up without networking.

    If a wired connection is plugged in, the wireless connects as well. The ethernet cable can then be removed.

    Re: Ubuntu 12.04 32bit Lenovo s10 e Ideapad Cannot connect to wireless (BCM4312)

    It sort of works after I do this :
    Code:
    sudo mousepad /etc/network/interfaces
    and removed this from interfaces :

    # The primary network interface
    auto eth0
    iface eth0 inet dhcp

    but it stops working after a while until next reboot.

    Re: Ubuntu 12.04 32bit Lenovo s10 e Ideapad Cannot connect to wireless (BCM4312)

    Hi your /etc/network/interfaces should look like this..
    Code:
    auto lo
    iface lo inet loopback

    Huh,
    my s10 gave me no troubles with Ubuntu. It only gave me troubles when re-loading windows, because the WI-FI is part of the power management utilities. And I made the classic error of not having the external WI-FI switch turned on. I realize this is no help, but possibly may lead to a fix to your problem.

    Hi Hadaka,

    Yes, mine looks like that.

    But it was still timing out when I downloaded a lot of files or large files.

    So after editing interfaces, I did this :

    Code:
    sudo mousepad /etc/modprobe.d/b43-pci-bridge.conf
    and added the line :
    options b43-pci-bridge.conf nohwcrypt=1

    Also in network-manager, under IPv6 settings, I changed "Method" to Ignore.

    So far it seems to be working, except that downloads via synaptic,terminal and websites like ubuntuforums.org seem a bit slow. Normal web browsing,streaming and http downloads seem fine. I will test for a few more days.

    Thank you
