If you are using the b43 driver from linux-2.6.24, follow these instructions.
# cd /home/byte
# wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
# tar xjf b43-fwcutter-011.tar.bz2
# cd b43-fwcutter-011
# make
# export FIRMWARE_INSTALL_DIR=”/lib/firmware”
# wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
# tar xjf broadcom-wl-4.80.53.0.tar.bz2
# cd broadcom-wl-4.80.53.0/kmod
# sudo /home/byte/b43-fwcutter-011/b43-fwcutter -w “$FIRMWARE_INSTALL_DIR” wl_apsta.o
# reboot
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.
wah..laptop baru ya pak..
Biasa… laptop kantor…
Langkah diatas sebelum atau sesudah install driver pake ndiswrapper seperti di gutsy? saya uda ikutin tutorial diatas tapi malah engga ke kedetect wifinya.
bisa bantu? saya install di lenovo 400
Lakukan langkah2 diatas, sebelum menginstall ndiswrapper, klo sudah terlanjur, coba di remove dulu ndiswrappernya
Good luck
Can you post the result of the command “iwconfig”.
Just to get an idea of the speed and connection quality you get. (I got between 1 and 5mbit for that driver, that’s why I wrote an ndiswrapper howto here: http://nxadm.wordpress.com/2008/05/21/broadcom-wifi-bcm4312-speedup-on-ubuntu-804-on-a-hp-nc6320-laptop/ .

@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.
Yup, but i got intermittent connection after it
and i go back to my tutorial above…
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
I have try to use windows driver from cd (lenovo 3000 g4000) with the newest ndiswrapper, but not succesfully
again…. back to the my tutorial above
@invaleed
Ndiswrapper is now working on me. My reference is this page: http://tek4dpipol.blogspot.com/2008/04/ubuntu-hardy-on-lenovo-g400.html
Instead of downloading the Windows driver, i simply used the one with the CDs.
I also did some changes on the order of the steps.. actually i simply opted to reboot after the last step and ignored the reboot step on the middle of the instructions.
I hope this helps.
@ dave
Can you post output from command #iwconfig ?
@invaleed
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.
Great…. Bit Rate:54 Mb/s, ok thanks for dave, nice to meet you..
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.
Hi,
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 2.6.23.17-88.fc7, could this be the cause ?
Regards.
hi,
i followed ur instructions but got stuck in the “make” step. an error says something like “so such symbol: ‘flags’”
what could be wrong?
thanks
Hmm… sorry i have no idea…
hi, bro… sekalian numpang nanya, kalo untuk fedora10 cara peng-installan untuk G400 Lenovo gimana ya ?
thanks
very bizzar this I have an asus a6000 a6k with this crappy chip … i followed these steps and no result … during the boot on my ubuntu the wifi light was on but once in ubutu gnome desktop it just went out again … afther this i installed manually my Gforce graphics card (mobile cards not detected automatically) and rebooted … ET VOILA the wifi is working perfectly. Now idea why i needed to reboot 2 times.
When I set up lenovo 3000 G400 for Wireless, It message that” Limited and no connectivity? How can I Set up it?
