Comment 5 for bug 415472

Using lenovo s10 netbook. Has Broadcom Corporation BCM4312 802.11b/g (rev 01) hardware for wifi.

Install karmic-netbook-remix iso for today oct 18, 2009 dated 03:05
o passed disc test on thumb drive
o runs live without showing wifi
o do an install

tried each of the following as recommended by several Internet finds using google.com

1. sudo apt-get install bcmwl-kernel-source
    shutdown system
    reboot still shows no wifi interface
    sudo apt-get install --reinstall-kernel-source (this recommended at one site as a fix)
    reboot and still no wifi

2. went to http://www.broadcom.com/support/802.11/linux_sta.php
     downloaded README.txt and tarball for 32-bit drivers

     a. first ran lsmod | grep "b43\|ssb\}wl" and got several listings with b43 and ssb (no wl)
          did the rmmod b43 and rmmod ssb

     b. sudo echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf (BTW I had to sudo chmod 777 to get this to work)
                               was getting permission denied even though rwx for root allowed --- strange IMHO
          sudo echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf

       upon rebooting system later ssb is still shown by lsmod and check shows that PPID of init (PID 1) uses it.

     c. sudo apt-get install build-essential (via eth0)

     d. make
          sudo make install

          these two steps for broadcom source using Makefile they provide

     e. shutdown

     f. reboot and still not wifi

     g. sudo depmod
          sudo modprobe wl

      still no wifi

I am sorry that I can not provide more info as this is not my area of expertise, but I do follow
instructions. I think. :-)

FYI
