[SOLVED] BCM43241 wireless card seems to not exist.

trusktr · 2013-11-10 18:51:58

Hey guys, I'm trying to install Arch on a Sony Vaio Duo 13. Unfortunately, it only has a wifi card and no ethernet port. Usually, installing wireless card drivers involves using lspci to detect what card I have, then finding the drivers and firmware for it. But this time the card (BCM43241) does not show up at all in Arch (it works in Windows). There's no trace of it with lspci or lsusb (fyi: it's a builtin card).

Here's my lspci and lsusb output:

lspci:

00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Controller )rev 09)
00:02.0 VGA Compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
00:03.0 Audio device: Intel Corporation Device 0a0c (rev 09)
00:14.0 USB controller: Intel Corporation Lynx Ppoint-LP USB xHCI HC (rev 04)
00:16/0 Communication controller: Intel Corporation Lynx Point-LP HECI #0 (rev 04)
00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04)
00:1f.0 ISA bridge: Intel Corporation Lynx Point-LP LPC Controller (rev 04)
00:1f.2 SATA controller: Intel Corporation Lynx Point-LP SATA Controller 1 [AHCI mode] (rev 04)
00:1f.3 SMBus: Intel Corporation Lynx Point-LP SMBus Controller (rev 04)

lsusb:

Bus 002 Device 002: ID 0bda:58df Realtek Semiconductor Corp.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0bda:5722 Realtek Semiconductor Corp.
Bus 001 Device 002: ID 0930:6545 Toshiba Corp. Kingston DataTraveler 102 Flash Drive / HEMA Flash Drive 2 GB / PNY Attache 4GB Stick
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Any thoughts on why the device doesn't show up? Is there any other output I can provide?

do you know how the device attaches in Windows? (USB, PCI, SDIO?)

I have the Asus T100, which apparently uses the same BCM43241 chip, but through the SDIO interface

inside dmseg, I can see brcmfac trying to init the chip 4324, but fails.

see this for more info on your vaio. looks like it does connect through SDIO

Does it show up in lshw?

paperwastage · 2013-11-10 21:24:18

looks like they added the firmware file for BCM43241 in the git repo...

http://git.kernel.org/cgit/linux/kernel … 83ecbb3493

//researching steps on actually loading this during bootup by brcmfmac, most likely copying the files to /lib/firmware/brcm and putting nvram there as well

@paperwastage. I'm not sure how to tell if connects through SDIO, but yeah, based on that link you posted seems like it does. But when I do dmesg | grep brcm is shows aboslutely nothing. There's no trace of my card anywhere. It just seems like Arch has no clue that the card exits (let alone that it's a wireless card). Does yours at least show up with lshw or lspci?

@COPE lshw shows no trace of any wireless card. I see some output at the bottom that looks ambiguous, but it's scuzzi.

  *-scsi
       physical id: 1
       bus info: scsi@4
       logical name: scsi4
       capabilities: scsi-host

nope, mine doesn't show up via lshw/lspci/lsusb, probably because it's not connected to the pci / usb bus (probably connected directly to SoC)

maybe your kernel doesn't have brcmfmac loaded. try this in root

#unload brcmfmac
modprobe -r brcmfmac
#reload brcmfmac
modprobe brcmfmac

note down the logs that should print on screen (and in dmesg)

also, go to windows, use some application to read your system (I've used http://rh-software.com/)

it showed my Broadcom 802.11abgn Wireless SD Adapter mounted on "SD\VID_.....", which is the SDIO port

@paperwastage demesge shows "usbcore: registered new interface driver brcmfmac" after `modprobe`ing brcmfmac. Nothing prints on screen. Hmmm... I think I'm going to go to walmart and try to get a wifi dongle instead of spending more time on this (so that's how I'm solving this).

Hi.

I can not boot the LiveUSB of Arch into my VAIO Duo 13 (blank scren).
Into nomodeset -> Error: conflicting fb hw usage inteldrmfb vs efi vga

You can help me?

Thnks,
Miguel.

Hi,

Finally somebody else got this laptop. I've been searching for weeks.

I managed to get a kind-of working nvram and firmware file from a broadcom employee. It feels rather sketchy to upload that stuff somewhere because it might brick something (maybe?).

So I'll just post the mailing list post which was answered by the employee in question and maybe you guys get the files from him. He said they wanted to publish them if they worked. However, I have not heard back after my last feedback.

Most of the time I have to do modprobe brcmfmac, try to connect, get no dhcp response, modprobe -r brcmfmac, modprobe brcmfmac and then I usually get a connection. So if you get the files, keep that in mind.

@LeugimSan, You need to create your a custom install media with GRUB. The default Install Media doesn't work on these Duos.

@janno, That's cool! Please do post back on how that goes. I don't currently have the Duo anymore (gave it to my little sister with Windows 8 restored onto it), but it might come in handy for others.
