    Wireless networks not showing up / Lenovo Thinkpad with Ubuntu

    Hi, I recently installed Ubuntu 12.04 alongside Windows 8 on my Lenovo Thinkpad. Everything works fine except for the wireless networks, which don't show up at all (wireless still works fine on Windows 8). I've tried troubleshooting from other threads with this same issue but so far nothing has worked.

    I've activated my wireless driver in the System Settings, but the wlan0 doesn't show up when I run the following commands:

    Code:
    $ lspci -nn | grep 0280

    It doesn't look like the required driver was installed. Please post the outputs of the following commands -
    Code:
    uname -mr
    lspci -nnk | grep -iA2 net
    dpkg -l | grep bcmwl
    apt-cache show bcmwl* | grep Version
    lsmod | egrep 'b43|brcm|wl'

    I had the wireless halfway working at one point (the available networks were showing up, but I couldn't connect to any of them). In the process of trying to fix that, I made the wireless networks not show up again. So there's really no telling what all I've done.. I thought about just reinstalling Ubuntu so I could start fresh.

    Re: Wireless networks not showing up / Lenovo Thinkpad with Ubuntu

    Please try this (while being connected via Ethernet) -
    Code:
    sudo apt-get purge bcmwl-kernel-source
    sudo apt-get install bcmwl-kernel-source=5.100.82.38+bdcom-0ubuntu6
    You may need to reboot after this for the change to take effect. Does wireless work any better? If not, we may have to try manually installing a newer version than what is available by default for you.

    Re: Wireless networks not showing up / Lenovo Thinkpad with Ubuntu

    Ok, so I tried the codes you posted and I got an error when running the second one. My wireless driver was deactivated and when I tried to reactivate it, it said there was an error. So I ran this:

    Code:
    $ sudo apt-get install --reinstall bcmwl-kernel-source
    $ sudo modprobe wl
    Wireless driver is activated and I actually have wireless networks showing up. But when I try to connect to one, it just continuously says connecting. It will ask for my username and password then open a window that says "No Certificate Authority certificate chosen". If I click "Choose CA Certificate" it takes me right back to the window where I type my username and password, if I click "Ignore" it tries to connect again and does the same thing.

    EDIT: After rebooting, the wireless networks don't show up. I have to re-run the codes above a couple times (why it doesn't work the first time, I have no idea). But eventually the wireless networks show up again.

    Re: Wireless networks not showing up / Lenovo Thinkpad with Ubuntu

    Do you have a working wired connection? Have you tried 'Updating' the system while being connected? Please do if you haven't -
    Code:
    sudo apt-get update
    sudo apt-get dist-upgrade
    And it would have helped a lot if you could tell exactly WHAT error occurred while running the second command I suggested. I can assume what it might be, but I don't want to rely on assumptions when we can have confirmations.

    Also, let's get a complete picture of your network configuration in one go instead of running individual commands. Please follow the "Wireless Script" link in my signature, download and run the script as per instructions there, and post back the report it generates.

    When I ran the codes you posted earlier, I got this when running the second one:

    Re: Wireless networks not showing up / Lenovo Thinkpad with Ubuntu

    Assuming you had not updated before, and this last one completed successfully, please check again which versions of the driver are available now -
    Code:
    apt-cache show bcmwl-kernel-source | grep Version
    If you see the version 5.100.... again, please try re-installing it -
    Code:
    sudo apt-get purge bcmwl-kernel-source
    sudo apt-get clean
    sudo apt-get autoremove
    sudo apt-get install bcmwl-kernel-source=5.100.82.38+bdcom-0ubuntu6
    ..and when (if) it returns the same error, post back the log file it referred to -
    Code:
    /var/lib/dkms/bcmwl/5.100.82.38+bdcom/build/make.log
    On the other hand, if you see a newer version (I'm expecting 6.30..), please report that also.

    There are lots of Access-Points with same name, which may sometimes confuse Network Manager. So which is the one (or which are the ones) that you are trying to connect?

    Re: Wireless networks not showing up / Lenovo Thinkpad with Ubuntu

    This is what I got for the version:
    Code:
    Version: 6.20.155.1+bdcom-0ubuntu0.0.2Version: 5.100.82.38+bdcom-0ubuntu6
    I'm not really sure why there's two.. or if it's supposed to be like that.

    I tried reinstalling again anyway and got the same error. So this is the contents of that file:
    Code:
    DKMS make.log for bcmwl-5.100.82.38+bdcom for kernel 3.8.0-36-generic (x86_64)Wed Feb 26 22:15:43 EST 2014

    make: Leaving directory `/usr/src/linux-headers-3.8.0-36-generic'
    After running all of that I checked the version again and it was the same as what I posted above.

    And I'm only trying to connect to the GTwifi.

    It is normal to have multiple versions available. They are just 'Available', and usually (but not always) the latest one is installed.

    Yeah, a known problem with that version of the driver, I thought it was patched in the repository versions, but apparently it is not. Used to be easily fixable but probably not worth the trouble. We'll try a newer version first, and see if it works better.

    Please manually download the file "bcmwl-kernel-source_6.30.223.141+bdcom-0ubuntu2_amd64.deb" from here : http://archive.ubuntu.com/ubuntu/poo...icted/b/bcmwl/

    Double-click to install it. If the Software Center does not let you install it (the install button remains inactive), install it with 'dpkg' command.

    Assuming you have copied the file onto your Desktop, this command will install it with dpkg -
    Code:
    sudo dpkg -i Desktop/bcmwl*.deb
    Watch out for errors and report back if there are any.

    Once it is installed, you would probably need another modification in your Network Manager connection file. Please check -
    Code:
    sudo cat /etc/NetworkManager/system-connections/GTwifi
    (assuming your connection is saved with the name "GTwifi". If not, please change it accordingly)

    The above command will just show the contents of you connection's "Key File". DO NOT POST its contents here as it also contains sensitive information like your security password (or remove the password before posting here).

    Do you see a line "system-ca-certs=true" in it? If yes, change its value to "false" with following command -
    Code:
    sudo sed -i '/system-ca-cert/ s/true/false/' /etc/NetworkManager/system-connections/GTwifi
    (again, change the name "GTwifi" if you have saved the connection with a different name)

    Then disable / re-enable wifi and retry to connect. Can you now?

    If still not, try deleting the line altogether -
    Code:
    sudo sed -i '/system-ca-cert/ d' /etc/NetworkManager/system-connections/GTwifi
    Any improvement?

    Lastly, if the newer driver fails to install (although I *believe* it shouldn't), is a fresh install an option for you? If not, we may try upgrading only your kernel so that it supports the newer driver properly.
    (as a last resort, we can also try to compile the same older driver 5.100... with the patch I mentioned, but that is a messy solution).
