I have a Broadcom Wireless card, which was obvious enough not to work just like that.
root@noor:/home/althaf# lspci -vnn | grep 14e4
12:00.0 Network controller [0280]: Broadcom Corporation BCM4313
02.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)Kernel configuration for (2.6.37 slackware 13.37 default)
Make sure you have enabled
Location: -> Device Drivers
-> Staging drivers
-> Exclude Staging drivers from being built
-> Broadcom IEEE802.11n WLAN drivers
-> Broadcom IEEE802.11n driver styleDownload the firmware
I was luck enough to have this card, well the broadcom guys had the mercy to open up their driver code, any way as usual it required firmware to be loaded.
[Firmware link]
We just need *bcm43xx-0.fw* and *bcm43xx_hdr-0.fw*, when downloaded make sure you have the same file name as given, the drivers have hard coded the path and firmware name in them, so it should be the same to work.
Copy them to /lib/firmware/brcm
Reboot
I highly recommend rebooting the system, though theoretically we could load the firmware on the go, however it didn't work for me.Once rebooted you will find wlan0 or similar interface.

Hi Althaf, I need your help.
ReplyDeleteI have a wireless device like his.
I did the following steps:
make menuconfig
Location: -> Device Drivers
-> Staging drivers
-> Exclude Staging drivers from being built
-> Broadcom IEEE802.11n WLAN drivers
-> Broadcom IEEE802.11n driver style
(X) broadcom IEEE802.11n embedded FullMac WLAN driver
make
make modules_install
cp arch/x86/boot/bzImage /boot/vmlinuz
download firmware and
but in my system don't have brcm in /lib/firmware
so I have created the dir and copy the firmware to inside.
After the reboot don't show my device.
What did I do wrong?
root@darkstar:/# cat /etc/slackware-version
Slackware 13.37.0
root@darkstar:/# lspci -vnn | grep 14e4

Are sure about the module being loaded?
ReplyDeletelsmod?
if you didnt have bcrm directory its fine, just make one and copy the fw as mentioned. Let me know if the module were loaded.

These are the modules that were loaded.
ReplyDeleteSorry for the late reply, i was busy.
ReplyDeleteWell seems like you haven't loaded the modules.Correct modules loaded will include.
1) brcm80211
2) mac80211
3) cfg80211
First lets bring the system to a known state, checklist the following
1) Do not overwrite the stock kernel image /boot/vmlinuz, it seems you have overwritten
2) From what you have done i came to understand the you haven't changed the kernel version string in the menuconfig, if you don't change, and use the same .config file from slackware, you will end up overwriting stock kernel modules in /lib/ , it seems you have done so.
3) First, i highly recommend restoring back the kernel image, reinstall the kernel from the slackware dvd you have, before that delete the /lib/modules/2.xxx ,then install it, reason i suggest reinstalling is, if at all you mess up the custom kernel, you need a back door to enter right ?
4) From the assumption of you have a stock kernel working, and installed, then rebooted.Do the next step.
5) Check the config file from /proc/config.gz, you can do the following 'zcat /proc/config.gz ~/default.config'
6) cd /usr/src/linux && 'make mrproper'
i assume you are using the kernel source from the slackware 13.37 DVD.
7) cp ~/default.config /usr/src/linux/.config
8) enable what i have said in my blog, do enable 2) mac80211 3) cfg80211 modules if you haven't done so.
Thanks, I will go to try again.
ReplyDeleteVery, very Thanks.
