Title: Wireless Issues: Broadcom BCM43xx
Post by: idoit on August 20, 2012, 12:33:25 AM

Hi all,
I use CorePlus 4.5.4 in my HP DV9000 series laptop and the wireless doesn't work out of box. dmesg indicates that a firmware is missing (please look at my attachment for the log).

Finally I found the correct driver for my Wireless. Following http://ubuntuforums.org/showthread.php?t=781747 (http://ubuntuforums.org/showthread.php?t=781747), I downloaded these:

Code: [Select]

http://downloads.openwrt.org/sources/wl_apsta-3.130.20.0.o
http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
and extracted the needed firmwares with b43-fwcutter (v0.12 NOT v0.15) using http://linuxwireless.org/en/users/Drivers/b43/#Other_distributions_not_mentioned_above (http://linuxwireless.org/en/users/Drivers/b43/#Other_distributions_not_mentioned_above) as instruction. (The Broadcom files mentioned in this article didn't do it for me.)

Then, I copied 3 files to /usr/local/lib/firmware/b43 :

Code: [Select]

b0g0bsinitvals13.fw
b0g0initvals13.fw
ucode13.fw
Now, when I use Wifi app to connect to my WLAN, it scans and detects it... I connect to it, it shows that an IP is assigned by dhcpd (please look at first screenshot, bottom) but I don't have internet access! (second screenshot, 3rd line shows my Wireless IP but hostname is unknown whereas my Ethernet connection [that I used to post this message] correctly has the hostname box.)

Please take a look at (first screenshot, top) to know specification of my HP laptop.

Thanks.


P.S. -1.My router is SpeedStream 6520 Series and it supports 802.11g protocol, so that shouldn't be issue!
P.S. 0. I connet to internet with WiFi of this laptop in Windows and Ubuntu, no problem there.
P.S. 1. With every restart (Reboot + Backup Option), /usr/local/lib/firmware/b43 loses my 3 files and I have to copy! How can it be done so they'll stay there?!
P.S. 2. Hopefully this thread can be a place to report all issues regarding B43xx wireless cards.
P.S. 3. When I disconnect my Ethernet cable, I can't even ping or access 192.168.2.1!
P.S. 4. ifconfig shows packages are dropped?!!!

Please read through this thread

to find pointers regarding the configuration of multiple network interfaces on same host.

Brilliant tinypoodle! Thanks aloud! :) Work like a charm.
How can I make it persistent, because when I reboot (with backup), /usr/local/lib/firmware/b43 deletes my firmware!

Did  you try firmware-openfwwf.tcz and wireless-tools.tcz ?
Works for my bcm4311.

Did you remember to add the line:

Code: [Select]

usr/local/lib/firmware/b43to your  /opt/.filetool.lst  file?

Also, you could use boot code "nodhcp" to prevent udhcpc from being started for eth0.

@gerald_clark and @tinypoodle: Thanks!
As the issue is resolved I think I'm good for now, and I won't load more extensions.

@Rich: I love you!!!  ;D
