Query : wireless service in ubuntu9.10

[raste ashish]

Hi friends,
Recently I have installed Ubuntu9.10 with a separate partition for it.
The problem I faced is that it wasn't able to detect the wireless service provided here at SASTRA (student network) eventhough having support for driver.
The essential details of my laptop are as :
1.Model : HP Pavilion
2.Wireless driver : Broadcom
               I hope that this problem will be soon solved with your valuable suggestions.

This problem is with those laptop having Broadcom wireless card.
You can solve this problem by following these steps.
1)  First download the archive with drivers here:
     http://www.broadcom.com/support/802.11/linux_sta.php
2)  Then if you installing it for first time then
       a) First extract the hybrid-portsrc-x86_32-v5.10.91.9.3.tar.gz in home directory.
       b)# cd hybrid-portsrc-x86_32-v5.10.91.9.3
       c) Build the driver as a Linux loadable kernel module (LKM):

           # make clean   (optional)
           # make

        When the build completes, it will produce a wl.ko file in the top level
          directory.
     d) Remove any other drivers for the Broadcom wireless.

           There are several open source drivers that are used to drive Broadcom 802.11
       chips such as b43 and ssb. If any of these are present they need to be removed
       before this driver can be installed.  Any previous revisions of the wl driver also need to
       be removed.

       # lsmod  | grep "b43\|ssb\|wl"

       If any of these are installed, remove them:
          # rmmod b43
          # rmmod ssb
          # rmmod wl
      e) To blacklist these drivers and prevent them from loading in the future:
         # echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
         # echo "blacklist b43" >>f /etc/modprobe.d/blacklist.conf
      f)The path to previous driver is usually
         /lib/modules/<kernel-version>/kernel/net/wireless
       Here kernel version is 2.6.31-14 for ubuntu 9.10 and 2.6.28-11 for ubuntu 9.04.

        # cd '/lib/modules/2.6.31-14-generic/kernel/net/wireless'
        # mv wl.ko wl.ko.orig
        # cp /home/shailesh/hybrid-portsrc-x86_32-v5.10.91.9.3/wl.ko /lib/modules/2.6.31-14-generic/kernel/net/wireless/wl.ko
        
         Here shailesh is home directory in my laptop.Change it according to your login name.
      g) Now your terminal should look like this:
           root@shailesh-laptop:/lib/modules/2.6.31-14-generic/kernel/net/wireless#
           Now execute these commands.
           # depmod
           # modprobe wl
           # modprobe lib80211
           # insmod wl.ko

 wl.ko is now operational.  It may take several seconds for the Network Manager
to notice a new network driver has been installed and show the surrounding
wireless networks.
      h) Now you have to update your ubuntu 9.10 for proper functioning of wireless driver
          otherwise you may have to repeat the a different  procedure.
3)  So if you have followed all previous steps and after reboot , still wireless service not
   detected then Follow these steps.

    # echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
    # echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
    # lsmod  | grep "b43\|ssb\|wl"
If any of these are installed, remove them:
    # rmmod b43
    # rmmod ssb
    # rmmod wl
    # cd '/lib/modules/2.6.31-14-generic/kernel/net/wireless'
    # depmod
    # modprobe wl
    # modprobe lib80211
    # insmod wl.ko
