Rebranding Broadcom 802.11a/b/g/n Cards as Airport

In this guide, I’ll be showing you on how to rebrand a Broadcom card which OSX detects as a Third Party Wireless card to Apple’s genuine Airport card. There are few reasons on why you should rebrand. Well , I would quote what BuildSmart and chrand have said about it :-

Basically I purchased the Linksys WMP300N wireless card with the hopes that it would work seamlessly in OSX. After fiddling with it for a while I was able to get it to work, but not at N speeds. I started doing some research and found that it would not work because its vendor and product IDs were not on Apple’s whitelist. One way to get it to work is to change the card’s IDs so that is on the whitelist.

Chrand of Insanelymac

Knowing me. So I tested out this hypothesis and its indeed true. For instance I’ve noticed that my BCM4321 (non apple branded) preformed kinda slow as in internet surfing , connection dropouts. I thought I am the only one. After checking out forums such as InsanelyMac,  I found out that I am not the only one. Thankfully BuildSmart found a solution on how to rebrand these cards so that OSX would see them as genuine apple airport cards thus giving us full N speed. Anyhow , I got my hands dirty and did that. The guide written by Chrand was simple but then it was out of date and it did not include pictures to help folks who are new to Linux. I thought of blogging about it and sharing on how to do it. So you may ask what are the advantages of doing so. Let me list em all for you :-

  • Makes it more vanilla (since everyone is talking about going retail and want to be as close to a real mac as possible)
  • Immunity against system upgrades (yes its true if you use a generic card however knowing how Apple works. They could simply blacklist non-Apple Broadcom cards so that they would not work at all). Its just possible
  • Increases your confidence level so you’ve finally managed to do something that is related to low-level hardware stuff
  • increases resale value of the card (in case if you want to sell it back. Suppose if you bought it for $10 , now you can sell it for $20 or so and you can say that its 100% genuine apple card instead of third party wireless)

Before you do this , be warned that there is a risk involved here. If you did something wrong here , it could render your wifi card useless. Don’t tell me I’ve warned you. I’ve already tested this method with couple of my friends over @ #snowleopard and found out that it did work and it did not ruin their laptops and desktops. Thanks Galaxy and apoc 😛

Basically , you’ll be needing the following stuffs ;-

  • Broadcom Wireless Card (such as Dell 1505, 1510 , 1490 , 1390 , etc) (which OSX sees as a third party wireless)
  • Ubuntu 9.10 Live Disc (no we will not be installing Linux) (if you dont have a CD Drive , for instance a netbook then you can Google yourself on how to run Ubuntu 9.10 on a usb disk. For instance I used this software. I used my 2GB flash drive and just pointed out where is my ISO and it did work. Oh yeah it requires Windows) – Ubuntu 9.04 would work as well
  • An Active Internet Connection via Ethernet or by other means (i.e 3G Wireless) (as Wireless will not work during this time) . So I recommend you to plug in ethernet cable !

1. Firstly run Ubuntu in Live Mode. We would not be installing ubuntu to our PC. If you have linux installed (any variant) then you may want to use that. But I’ll be solely focusing on how to do it in ubuntu and if you’ve a linux of another distribution (i.e SuSe)

2. Fire up Terminal. Its located in Applications -> Accessories –> Terminal

3. Be sure to test if there is any Internet connectivity (i.e if the cable is plugged in and such) , to do so type ping If you get responses , voila you’re on the Internet. If not check your cable  (I’m assuming that you’ll be connecting the PC via ethernet). Again let me tell you this , WiFi Will not work at this time !

4. Once that is done , type lspci in Terminal and you should see something like this ;-

Be sure that you see something like Broadcom Wireless . Okay so if you see Broadcom Wireless , you’re good to go

5. Next up is for us to grab the needed tools which are :-

sudo apt-get install build-essential
sudo apt-get install curl
sudo apt-get install git-core

Notice I use type sudo -s and apt-get install build-essential curl git-core as it saves me time. i prefer to do this way . Do wait for a while as it could take some time for it to download.( as you can see in the image above) :-

6. We’ll be installing this driver. Type apt-get install b43-fwcutter && modprobe b43 (make sure that you’re running it as root otherwise add the sudo command). If you are not sure , check the picture below :-

7. It will prompt you to extract the firmware , in this case just hit yes. The process would once again continue , and it would fetch several files for it to work. Again this is relatively fast if you’re on a high-speed broadband connection but it certainly took me a long time to get these files

8. Once that is done , we’ll be getting the latest ssbsprom tool which is used to extract our wireless card’s firmware in order for us to change its device subids to match of an apple’s wifi card.

git clone && cd b43-tools/ssb_sprom && make

You can just copy and paste the above command. Once you’ve done that. Type

cp ssb-sprom /usr/sbin/

chmod 755 /usr/sbin/ssb-sprom && chown root:root /usr/sbin/ssb-sprom

Once everything is ready , now here comes the crucial part , type

SSB_SPROM=$(find /sys/devices -name ssb_sprom)

and then followed by echo $SSB_SPROM

If you see something like /sys/device/pci/<numbers>/ssb_sprom. Then you’re in luck. But when you type echo $SSB_SPROM and you get nothing. You should stop now as ubuntu does not see your wireless card. However if you see more then 1 entry , you should consider reading this

Suppose if you see something like as above , then type

cd && cat $SSB_SPROM > ssb_sprom_copy


sudo ssb-sprom -i ssb_sprom_copy -P

What this does is that it dumps the ROM from the device to a file. You’ll see something like this. Take note of Subsystem Product and Vendor ID. (Oh by the way I’ve flashed mine to Apple IDs , so yours may differ) . Again the positioning of your vendor id may differ as each card has its own SPROM revision. If you notice mine is a revision 5 SPROM. It just means I am using the 5th version of Broadcoms ROM. There is up to version 8.

Okay next up we’ll be changing our subsystem vendor ids to match of an Apple product. Since I’ve a BCM4328 which is also used in a macbook air. I’ve changed mine to 008B. However if you have 4328/4321 and if you would like to match of a MacBook Pro/MacBook then its

ssb-sprom -i ssb_sprom_copy –-subv 0×106b –-subp 0×0087 -o new_ssb_sprom_copy

What this command does is that it copies the old rom , changes the sub vendor id (0x106b which is Apple Computer , Inc) and sub vendor product (to match of an Airport ID) and copies it a new file !

Suppose if you use a Broadcom a/b/g Wifi card , then the subp id is 0x004e , you’ll just have to change that. Once you’ve done that , lets review our changes. To do so , type

ssb-sprom -i new_ssb_sprom_copy -P

Once you’re happy with your changes (be sure to check of the other IDs and make sure they aren’t changed). Then let us issue the final two commands .


This is just to check that Linux sees our drive and now for the command that would flash our device. Be sure that you’re connected to AC and be sure to double check your rom against with the old one to make sure you did not fiddle with other settings. Lastly but not least , make sure you aren’t doing it on a HP laptop or IBM laptop or any laptop which whitelists Wifi Card. Okay , I’ve guessed I’ve warned you enough. Now let us cross our fingers and issue this command

sudo cp new_ssb_sprom_copy $SSB_SPROM

This could take anywhere from several seconds to several minutes. Be patient . Once its done ,(that is if it does not give any error messages) type sudo reboot or sudo reboot -n

Reboot back to OSX and check out system profiler and select Airport and you’ll be amazed.

Troubleshooting and Additional Information

  1. If the speeds are way to slow. Trying swapping the grey and black antennas that should do the trick for you.
  2. Here is another tip from Christian , basically by changing the ‘Region’ to US and FCC , you could able to unlock speeds up to 300Mbps  – However bear in mind that you may be violating the laws of your country if you do this.

I’ve taken this idea a little further with an HP branded half-height BCM4322 a/b/g/n card that I got from eBay to replace the stock b/g card in my Dell mini10v . WIFI kit is regionalised a little like DVD players, and different regions permit different channels to be used. I have a US purchased TimeCapsule router and the HP card I bought was set to DE for Germany. The FCC in the US allows pretty much everything but DE restricts some channels and it meant the highest speed 5GHz mode that the TimeCapsule offers was using channels not visible to the HP card. So.. as well as switching the vendor/product ID’s around to match an Apple Airport Extreme I’ve also changed ‘regrev’ to be 0×0001 (an educated guess) which shows up as FCC in System Profiler and ‘ccode’ to US (it’s a text string, not hex) from DE. On reboot I now have access to channels 149+ on an Apple Extreme branded card ;) and Network Utility is reporting a link speed of 300Mbit/sec. Legacy region settings probably explains why some folk aren’t seeing link speeds over 130MB/s on some cards even though they are now detected as ‘Apple’ models. Enjoy! – Christian

  1. Hi,

    Fantastic How-to but I have a slightly different issues that I hope you can help with. I have bought a Dell Wireless 1510 that I want to make compatible with HP Pavilion DV6 (the chipset is compatible it just doesnt like it being Dell) I can bypass the whitelist by putting in the card AFTER to power on test so I wondered if you knew

    1) If this same process would work but with HP Subsys and vendor

    2) What the above are for a HP card?



  2. What about the cards with the newest broadcom chips (4313, 43224, 43225). Is there any solution for them yet?

  3. Just bought an ‘ersatz’ BCM94322MC off ebay – changed subp to 0x0093 and subv to 0x106b, and now my card is reported as ‘Airport Extreme’ 😀

    That’d be a BlackBook 4,1 with AirDrop enabled then…

    Thanks to those that developed and published this technique!

  4. Forgot to mention 😳

    I used Ubuntu live 32bit 10.04LTS

    And you absolutely MUST not use the wireless interface at any time prior to carrying out the technique (whilst booted into Ubuntu, of course). Use wired ethernet for simplicity.

  5. BCM4311.
    Just trying this with Linux 9.04 and Mint 8 and both were coming back with failed to fetch on the curl and git-core files. Downloaded Ubuntu 12.04 LTS x86 and

    sudo apt-get install curl git-core build-essential worked.

    I get to sudo git clone git:// && cd b43-tools/ssb_sprom && make

    and it says: fatal: unable to connect to name or service not known. A bit of reading later I used:

    sudo git clone git:// && cd b43-tools/ssb_sprom && make

    and after all that I get nothing, might try again just to see if I get something lol.

  6. It does not work for BCM43224. Cannot find ssb_sprom under /sys/devices folder.

    Is there a way to re-brand the 14e4:4353 card?

  7. Hi Prasys,

    I bought a BCM943224HMS, I wanted to branding as original card of my Laptop Hp, then change dev ID prod ID and subsystem. Then be transformed into E414: 4727 xxxx: 103c as in the whitelist

    Do you think it possible to work, Idea of how can change the commands?

  8. The command for retrieving the source b43-tools GIT process is:
    git clone git://


  9. I’m trying to rebrand a Broadcom 43228, but only the wl (STA) driver recognizes the 43228. The “echo $SSB_SPROM” command gives an empty field.

    Is there a tool that is able to edit the sub vendor id and sub vendor product and compatible with the 43228?

  11. Attempting rebrand BCM43222 card but Ubuntu won’t recognize the card; others have done it.
    Anyh ideas?

  12. Or instead of pissing your life away on mundane shit like this, you could buy a card that’s compatible and call it a day.

  13. Hello. Are there any news about rebranding BCM43224?
    I don’t see ssb_sprom under /dev/devices too 🙁
    I tried to compile kernel with enabled CONFIG_B43_BCMA_EXTRA option. The only thing is changed – my adapter begin operate with b43 module instead of brcmsmac, but there is still no ssb_sprom file under devices directory 🙁

  14. Hi Pradeesh.

    Yes, I know that it is a different chipset.
    But maybe there is some solution for its rebranding too?
    Thank you.

  15. Hello AGluk , it seems that folks of OSX Latitute have also hit the same problem. I’m looking into it. Could we use same trick and would it work. It has been a long time since i’ve touched OSX86 internals !

  16. I’ve just tried this procedure with one BCM94322HM8L and Ubuntu 13.10 and it works like a charm. The only difference is the Broadcom firmware should be installed manually as it’s written here:

    and the b43 module should be restarted with:

    sudo modprobe -r b43 && sudo modprobe b43.

    My question is: is it enough only the ccode parameter to be changed in order to get all channels, permited in the EU (using this list of region codes: or the regrev parameter should be edited as well (currently set to 0x0002) and if it should be edited, is there a list of a possible values for it that I can find somewhere?

  17. my laptop wifi is broadcom BCM943227HM4L. this solution support this chip?
    after rebrand broadcom if need windows driver installed or not because rebranded chip?
