    Wireless Configuration

    Hello, I am trying to set-up my wireless card. I am running Kubuntu 9.04 (kernel The card I have, according to the lspci command I am using Broadcom BCM4313 Network Card. I went to this site to locate drivers because I am able to see my wireless device, connect, but I cannot do anything on any websites. Here is my driver: broadcom.c_m / support/802.11/linux_sta.php

    I burned the disk with my other 64-Bit computer in mind, so my distro is 64-bit.

    I ran lsmod and dmesg, but I didn't see anything related to my wireless device.

    I believe this is all the information that the post asked, but if you need more, please feel free to ask. I have attached my LSPCI file.

    Thanks for any help.

    That's why I linked to it. The text file that had instructions on how to run the driver didn't work for me. When created the directory I ran the install on that directory and it said error because the directory didn't exist or something like that. Maybe you can explain the steps involved better to create the LKM?

    I was using this site - h__p://linuxwireless.o_g/en/users/Drivers/b43#firmwareinstallation (.org), and I can see that I am connected to my wireless router, BUT I cannot visit any websites. Can someone help?

    I believe 9.04 comes with the driver you linked to installed. I know you said dmesg and lsmod didn't contain anything useful, but please do post them. Enclose the output is [code] tags as described in that link.

    One option is to remove the Broadcom STA driver, and use the open source b43 driver. Ubuntu will have the driver already installed, but you need to the firmware as well. If you have a wired connection, download the b43-fwcutter package to get the firmware. More info here.

    Note that the b43 driver should be blacklisted, so it won't interefere with the current driver; if you decide to use it, you'll need to remove it from the list at /etc/modprobe.d/blacklist

    Maybe I can explain this in detail.

    There are actually two Linux drivers for Broadcom wireless chips. One is developed as a completely open-source driver, and includes the b43/b43legacy drivers. The other was developed by Broadcom, and is not open-source. It contains the wl driver. They cover different wireless chips, so there really isn't much overlapping, except for one card. That wireless is the 4312 wireless.

    Your wireless card (4312) seems to be one of the overlapping ones. There is no predicting which driver Ubuntu is loading for the card, so we need the outputs of lsmod and dmesg. It may even be loading both drivers, so that would keep it from working.

    I would suggest using the Broadcom STA driver (wl) for this card, and removing and blacklisting the b43 driver.

    Can you tell me how to copy my output? I'm a bit new to Linux, so I am not sure of the commands.

    Another board suggested I run this:

    echo 'deb h__p://apt.wicd.n_t hardy extras' | sudo tee -a /etc/apt/sources.list
    wget -q h__p://apt.wicd.n_t/wicd.gpg -O- | sudo apt-key add -
    sudo apt-get update
    sudo apt-get install wicd
    And, I got the wicd manager, but when I try to connect, I type in the router password and press connect. It works fine, then it gets stuck on "Obtaining IP address" Any idea why? I know the wireless works because I am on it now. Maybe there is a manual way I can do this?

    I tried to do a static IP, but it stopped at "Validating Authenticity." I thought that may have solved it, but no go.

    I'll look get the outputs of lsmod and dmesg. Thanks for the help and suggestions.

    Here are lspci.txt, dmesg.txt, and lsmod.txt.

    If you need me to get anything else, please say so.

    You have eth0 running b44 driver, (that would be wired internet) and wl driver for the wireless, according to dmesg and modprobe.. Maybe disable wl and enable b43 driver to see if that allows it to work.
