If you are using the b43 driver from linux-2.6.24, follow these instructions.

Note that you must adjust the FIRMWARE_INSTALL_DIR path to your distribution. The standard place where firmware is installed to is /lib/firmware. However some distributions put firmware in a different place.

    @Sir Invaleed:

    I read from claudio’s blog that you did some editing on his script and voila a faster wireless connection.

    May I know please what were the modifications you did on his script as we both have the same Lenovo 3000 g400?

    Thank you, will wait.

    I see, the problem is that I can’t connect to some places.. probably perhaps the connection is too slow?

    Uhmmm.. I will stick to your tutorial for a while.

    Question: I have some CDs where the Windows driver for the wireless card is included. Don’t you think that would work better?

    @ dave asuncion, jr

    Yes, make me very difficult to connect Access Point πŸ™

    I have try to use windows driver from cd (lenovo 3000 g4000) with the newest ndiswrapper, but not succesfully πŸ™

    again…. back to the my tutorial above πŸ™‚

    As requested, here is the iwconfig result:

    wlan0 IEEE 802.11g ESSID:off/any
    Mode:Managed Frequency:2.462 GHz Access Point: Not-Associated
    Bit Rate:54 Mb/s Tx-Power:32 dBm
    RTS thr:2347 B Fragment thr:2346 B
    Power Management:off
    Link Quality:0 Signal level:0 Noise level:0
    Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
    Tx excessive retries:0 Invalid misc:0 Missed beacon:0

    I hope this helps. So far no on and off connections and I was able to connect to the AP at the Mall where I use not to be able to connect.

    And nice to meet you too. You’re actually the one who got me into the right direction. Keep it up!

    Just a newbie, and forever be one. πŸ™‚

    I’ve just installed Fedora 7 on Lenovo 3000 G400 and followed your instructions to install the Wireless driver, but it’s not working. FYI, currently the kernel version is, could this be the cause ?


  9. pablo ouano says:


    i followed ur instructions but got stuck in the “make” step. an error says something like “so such symbol: ‘flags'”

    what could be wrong?

Now idea why i needed to reboot 2 times.

    Just connect to internet using wired connection. Than install the hardware driver using Systemβ€”->Administration —–> Hardware Drivers.

    Than take a reboot and you will get the wifi is working in ubuntu.

    For pointing Device just press the Fn key and F8 and than just again press Fn+F8 to reenable it u will find the pointing device working
