    Can't setup wireless...

    Hi, my laptop Specs:
    -Dell Inspiron 1545
    -Ubuntu 12.4
    -Dell Wireless 1397 WLAN Mini-card


    I have tried installing various wireless drivers, I've had people try to set it up for me....I've tried to install Broadcom and I didn't really know what I was doing, I tried to install a driver and I just got errors, I type my details of my wireless network in the network manager and just nothing happens...I don't know if it scans for it automatically or what, I don't know how to connect to it, I also tried WifiRadar after someone suggested it, I type my details of my network into that and click connect, and it simply does nothing, I can only connect to my network via wired with an Ethernet.

    Could someone who knows what they are doing give me some help and try and sort this out for me, step-by-step would be much appreciated as I'm new to Ubuntu, thanks.

    Re: Can't setup wireless...

    Dear Sam18,

    I'm not an expert but think I had the same problem and managed to make some workaround.
    Just in case get rid of old drivers:

    Code:
    sudo apt-get remove --purge bcmwl-kernel-source
    Block your sky2 driver:
    Code:
    echo "blacklist sky2" >> /etc/modprobe.d/blacklist.conf
    Then check if b43 drivers are not blacklister in /etc/modprobe.d/blacklist.conf

    Code:
    grep -e "blacklist b43"  /etc/modprobe.d/blacklist.conf
    If you get blacklist b43, then it is blacklisted. Put # in front of the line

    Code:
    sudo gedit /etc/modprobe.d/blacklist.conf
    Then install the drivers (if you have already installed lpphy driver skip it and install just b43-fwcutter:

    Code:
    sudo apt-get install firmware-b43-lpphy-installer
    sudo apt-get install b43-fwcutter
    And you can also do this, I don't know if it's neccessary:

    Code:
    echo "b43" >>/etc/modules
    Restart the computer and try my miserable trick:

    Code:
    sudo iwlist scan
    several times.

    This should not be needed -

    Why do you think it needs to be blacklisted?
    It is an ethernet driver and does not conflict with b43 as far as I know (and modinfo tells). Blacklisting it would disable the Ethernet interface.

    Hi sam18, I am a little confused by this..
    "Hi, I did this and I have copied the last lines of code after it connected."
    "after it conncted"
    is the wireless now working?
    these lines of code should be entered with the wired connection..connected to the internet.
    Code:
    sudo apt-get update
    sudo apt-get upgrade
    thanks.

    It seems a gateway error occurred while downloading the packages (was the connection interrupted?) -

    Ok I did

    Code:
    sudo apt-get update
    sudo apt-get upgrade
    and both came back succesful I think, here's the final code

    Code:
    Reading package lists... Done
    sam@sam-Inspiron-1545:~$ sudo apt-get upgrade
    Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

    EDIT: Available wireless networks in range now show on the dropdown list, they did not before, so i think it's fixed, I'll post back if it's not.
