[SOLVED] Broadcom BCM4313 not working

[alpage2]

I have recently installed gentoo on an old 32-bit netbook: Aspire One D-260A.

I seem to have succeeded - it is error free when I do deep world updates, and I have xorg and an xfce interface working, using the 'desktop' profile.

The sole exception is the broadcom wifi adapter - I just don't seem to have the kernel configured right, despite following the details in the gentoo wifi and kernel wikis. I couldn't find anything to help further on the gentoo forum.

The broadcom wifi adapter works fine when the system is booted with the minimum install disk, so I know it is working. As will be obvious from the outputs below, after booting, the wifi adapter is not detected.

I am not using an initramfs file - could that be the problem?

Can someone more experienced guide me to a working system? I expect it is something obvious, but I just can't see it.

Some hardware details:

The tail end of dmesg was the first sign of the problem:

So it seems the firmware for regulatory.db failed. I had followed the advice to make the b43xx driver a module to avoid this problem - so I am uncertain where this went wrong.

I see the Broadcom 43xx driver loaded, after various errors associated with 43 were reported - but the significance of that is lost on me.

I did try to emerge the broadcom-sta package, for good measure, but emerge reported that it was masked by the ~x86 keyword, I presume for good reason.

My list of modules is pretty small - I was trying to compile everything but the wifi modules into the kernel.
The ralink drivers are included because I was trying to get a ralink usb wifi adapter working as an alternative - again without success.

I think that for BCM4313 you need to install net-wireless/broadcom-sta

[alamahant]

You need firmware also.
Maybe.

[mustafasalih1993]

some useful tips for you:

- enable "Broadcom 43xx wireless support" as a module in your kernel
- install net-wireless/broadcom-sta
- blacklist b43/bcma, add the following in your /etc/modprobe.d/blacklist.conf

Code: Select all

blacklist b43
blacklist bcma

Direct firmware load for regulatory.db failed with error -2

From memory -2 is ENOENT or "no such directory entry"; do you have net-wireless/wireless-regdb installed, it should be pulled in by wpa-supplicant, that's what supplies the two /lib/firmware/regulatory.db* files?

You'll need sys-firmware/b43-firmware installed (along with sys-kernel/linux-firmware for brcm/bcm43xx*.fw I think). The list of firmware referenced in /usr/src/linux-5.10.27-gentoo/drivers/net/wireless/broadcom/b43/main.c is massive, so it's not as easy to dissect as graphics drivers to give you a list of needed fw from a device ID.

Seeing as it works on the livecd you can check what is blacklisted, though I suspect nothing. Searching through the livecd's dmesg should let you see a full list of firmware files loaded too.

Once you know what firmware files are needed, you can add them as

Code: Select all

CONFIG_EXTRA_FIRMWARE="regulatory.db regulatory.db.p7s some/broadcom/ucode-1.fw ... some/broadcom/ucode-n.fw"

in your .config and set your modules back to yes if you like.

[alpage2]

Many thanks to everyone for the detailed feedback. Due to limited access to this machine, and limited time, it may take some time to work through all the checks and changes, but I will post back here on progress, as time goes by.

So far, net-wireless/broadcom-sta has been unmasked and emerged, and b43 and bcma drivers blacklisted. I'll amend my .config file next, and recompile the kernel.

Thanks again.

[alpage2]

Making use of all the hints above, I modified the kernel configuration and recompiled the kernel, and the broadcom adapter is now working fine. In the end I did not need to do any blacklisting, or the listing of individual firmware files. With the right kernel modules, and the simplest example of handling WPA-PSK in wpa_supplicant.conf from the Gentoo Handbook, I was online by the end of booting up.

Thanks again for all the help.
