    Broadcom BCM4366 PCI-e driver won't load

    Hi All, I've recently purchased an Asus PCE-AC88 dualband wifi card. Things haven't been going to well. I'll get right to it. (Yes I looked at the "How to install a driver for the Broadcom series of PCI wireless cards" sticky post).

    dmesg reports this:
    Code:
    [ 2755.750897] brcmfmac 0000:07:00.0: Direct firmware load for brcm/brcmfmac4366b-pcie.txt failed with error -2
    [ 2758.086255] brcmf_pcie_download_fw_nvram: FW failed to initialize
    That file doesn't exist on my system. I've looked everywhere and the "NVRAM from EFI" section from https://wireless.wiki.kernel.org/en/...vers/brcm80211 doesn't help. I do not see that nvram file anywhere. Is there a special way to generate this?

    So I looked online and tried to use a hack where you can specify just the macaddr=<mac_addr_of_card>. Still didn't work as I still see in dmesg.
    Code:
    [ 2758.086255] brcmf_pcie_download_fw_nvram: FW failed to initialize
    Linux kernel and ubuntu are updated as of today.

    Unsure as to how I should continue. Any help is greatly appreciated!!

    Code:

    You need to see my connected wifi information in order to help?

    What information do you need, I'll post it.

    Just run the wireless script and post the complete file it creates in your home folder, the directions how to do it are in the link in my signature.
    Thanks

    Re: Broadcom BCM4366 PCI-e driver won't load

    I think we have more issues than that with this card. It is misidentified in the 4.4 kernel as a 4366b device when it is a 4366c device, see kernel commit
    It seems that the commit is part of backports-20160324 but the firmware file bcrmfmac4366c-pcie.bin is not in linux-firmware-next, see comment but it seems that they found something on Fedora forums http://forums.fedoraforum.org/showth...99#post1769999

    Re: Broadcom BCM4366 PCI-e driver won't load

    I'm not sure if I should start a new thread or not, but I also am in the same situation. I'm trying to get my Asus PCI AC-88 wireless adapter to work, and I've had no luck. I just upgraded to the latest kernel (4.9) in the hopes that this would work, but no luck.

    Anyone have luck with this card?

    Re: Broadcom BCM4366 PCI-e driver won't load

    Hi,

    I am also interested in a solution. I have updated to the 4.8 kernel. I can find the firmware files in the /lib/firmware folder.
    dmesg shows: brcmfmac 0000:02:00.0: Direct firmware load for brcm/brcmfmac4366c-pcie.bin failed with error -2

    Any solution to this?

    Unfortunately it seems that no progress has been made for this chipset

    Re: Broadcom BCM4366 PCI-e driver won't load

    What can we do? Its my first time I have a problem with hardware under Linux. I can live with the cable connection for some time but it would be great if we could achieve something since the firmware stuff seems to be there and the device is recognized. Some people made it (googled it) but I either could not understand and reproduce what they did or it did not work for me.
    E.g. extracting the FW from an Asus router firmware file.
    Found this: https://wireless.wiki.kernel.org/en/...vers/brcm80211 but the provided files seem to be alredy in the designated folders, at least with the 4.8 kernel, did not check 4.4.

    Any ideas?

    Re: Broadcom BCM4366 PCI-e driver won't load

    So I (original poster) figured this one out. It might help people in the future. I included steps for the latest firmware as of 03/10/17.

    1.) Go to the Asus support page and download the "other" firmware for RT-AC88U. (https://www.asus.com/us/Networking/R...Desk_Download/)
    - I'm using Version3.0.0.4.380.7266
    2.) Extract the firmware using binwalk: binwalk -e RT-AC88U_3.0.0.4_380_7266-g6439257.trx
    3.) Enter the _RT-AC88U_3.0.0.4_380_7266-g6439257.trx.extracted/squashfs-root/lib/modules/2.6.36.4brcmarm/kernel/drivers/net/dhd/ directory
    - You should see dhd.ko
    4.) Use read elf and search for 4366c0:
    readelf -s dhd.ko | grep 4366c0

    219: 000fe818 4 OBJECT GLOBAL DEFAULT 35 active_cons_4366c0
    228: 000fe7ec 18 OBJECT GLOBAL DEFAULT 35 dlimagever_4366c0
    248: 000fe73c 175 OBJECT GLOBAL DEFAULT 35 dlimagename_4366c0
    348: 000fe814 1 OBJECT GLOBAL DEFAULT 35 dlimagetag_4366c0
    479: 000fe800 20 OBJECT GLOBAL DEFAULT 35 dlimagedate_4366c0
    518: 000fe81c 0xe6450 OBJECT GLOBAL DEFAULT 35 dlarray_4366c0
    625: 000022e4 4 OBJECT GLOBAL DEFAULT 45 debug_params_4366c0

    5.) 0xe6450 is 943184 in decimal (this is the bin file size)
    6.) Open up another brcmfmacXXXX.bin in bless to compare the start and stop tags for another firmware (I'm using brcmfmac4366b-pcie.bin)
    7.) We see a start hex of "
    00 F2 3E B8" as a starting point and "FWID: 01-c47a91a4...." as ending (4 bytes past the denoted as periods
    8.) Search in dhd.ko using bless for "00 F2 3E B8"; Address at 0x137bbc which is 1276860 in decimal
    9.) Copy out the firmware using dd: dd if=dhd.ko skip=1276860 ibs=1 count=943184 of=brcmfmac4366c-pcie.bin
    10.) Open up the new brcmfmac4366c-pcie.bin file in Bless to check it out and ensure that we start with "00 F2 3E B8" and end with the FWID: "FWID: 01-fed440e1...."
    - sha1sum is "9f97ebaf661631d6aa303d5e74a528cf1d95a016 brcmfmac4366c-pcie.bin"
    11.) Put that in /lib/firmware/brcm and reaload the module.
    12.) Check dmesg on your system and grep for errors.

    This worked on my system and I now have perfect wi-fi using the
    ASUS PCE-AC88 4x4 Wireless AC3100 PCIe Adapter.
