    Re: broadcom wireless problem

    Hi thepisu,

    no, you can't use the old bcm43xx drivers any longer, something to do with the kernel, I think.

    Your output seems to be okay, just reboot if you haven't already done so and then use the network icon in the toolbar as per the pic on my previous post to configure the network, it should all work fine then.

    The iwconfig output indicates that you haven't configured a network as yet and that means that it won't authenticate with any, so this is the easiest way to configure a network in roaming mode, which you can check through SYSTEM > ADMINISTRATION > NETWORK...
    Let me know if there is anything else that I can do...

    My problem is strange in that way that wireless card is working (as you can see) but nm-applet does not work! I just extracted Broadcom firmware using b43-fwcutter and put it into /lib/firmware directory. I succeeded to establish wireless connection to my AP but nm-applet does not show list of available wireless networks around.

    lshw -C network

    I have one ethernet and one wireless card in my notebook but according to this output here is "network" and "network:1" for wireless!? It seems to me that "network" works since it received dynamic IP address from AP, and that nm-applet is assigned to "network:1". How's that I have "network" and "network:1". On my other notebook having the same Broadcom card with Fedora 8 there is modprobe.conf file where I define "alias wlan0 b43" to assign wlan0 to b43 driver but how it works here on Uuntu 8.04?

    I was in "roaming mode", autodiscovery, and it worked in 7.10...
    However, I tried to manually configure. New this is iwconfig result:
    Code:
    stefano@pisulinux:~$ iwconfig 
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    wmaster0  no wireless extensions.

              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    But, still doesn not work, and still there are lot of timeout messages in "dmesg"...

    (i tried also using ndiswrapper, but without luck..)

    It looks like you are not associated with a wireless network, you can do this through iwconfig if you like, manually, but I would recommend using nm-applet to do it, see my post with the pic and then authenticate. If it doesn't show it, then check your SYSTEM > ADMINISTRATION > NETWORK to make sure that your wireless card is set up to roam.

    If you can't do it that way and you can e-mail me your wireless settings and I'll send you back the bash commands to set up the network

    Good luck

    Re: broadcom wireless problem

    Did you set up the IP address manually? If you are using DHCP then you have a network connection, which would be a good thing.

    Let me know...

    Re: broadcom wireless problem

    You don't have a network connection as yet, your output should look similar to the one that is shown below.
    Code:
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
    
    wmaster0  no wireless extensions.
    
    wlan0     IEEE 802.11g  ESSID:"Home"  
              Mode:Managed  Frequency:2.437 GHz  Access Point: 00:1B:11:90:8C:52   
              Bit Rate=54 Mb/s   Tx-Power=27 dBm   
              Retry min limit:7   RTS thr:off   Fragment thr=2346 B   
              Link Quality=69/100  Signal level=-72 dBm  Noise level=-68 dBm
              Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
              Tx excessive retries:0  Invalid misc:0   Missed beacon:0
    If you are still having problems, I would suggest that you remove b43-fwcutter and also the file in b43 in /lib/firmware/2.6.24-16-generic and reboot and then start again, as it seems likely that there problems with the installation.

    You could also try doing the following in your second attempt, after you have installed the firmware and see if that helps:
    Code:
    sudo modprobe -r b43
    sudo modprobe b43

    Re: broadcom wireless problem

    still no luck in my end .. did notice a couple of things
    like this

    denarced@ubulap:/lib/firmware$ ls -a
    . .. 2.6.24-16-rt b43 b43legacy

    that's why your suggestion didn't work originally
    so I tried it with the 2.6.24-16-rt
    no luck

    any more tips ?
    thanks for all the help so far

    If you can't the b43 driver working reliably with your Broadcom card, and you would like to get ndiswrapper working with Ubuntu 8.04, check out the end of my earlier post:

    Re: broadcom wireless problem

    Hi mate,

    what does your restricted driver's manager have to tell us? SYSTEM > ADMINISTRATION > HARDWARE DRIVERS

    Are you getting any errors when you reboot in regards to your wireless card? If so, what are they?
