Just wanted to say thank you to all involved with finally allowing my d820 to have working ethernet after all this time (without buying an external solution)

90% Chance will,

But if you make it correct, 100% will.

you also can use the kext on my page to try on too .

Have fun

Ok.. I must have read this entire 33 page thread about 10 times and tried everymethod to get my Broadcom working.. but no luck... here are the specs:

Dell Latitude D620
10.5.2 Kalyway
Broadcom Netexteme 57XX (i'm assuming its the 5752 after reading all the threads)

What do I need to do to make it work ?

thanks in advance...

Liar!


If You'd really did so, or at least – used search, then You'd have found my post with links to 100% working kext.
See my sig for details.

please someone can help about Broadcom BMC5906 kext for Leopard 10.5.4???
any solution or ideas are welcome... please!!!

hey A...,

i tried your kext but my d620 doesn't see any hardware for the BCM5752. i am totally lost, please help me out.

thanks

Titto, niter,

this is not the way to ask for assistance.
Details you specified tells us nothing about your hardware.

Specify Vendor ID and Device ID, steps you did to make your hardware work and log output (or at least - your device part of it).

Any news about making a 5755 work ? I tired to install nisa's kext but it didn't do anything maybe I did something wrong ...

Genius....

I too have a Dell 390, and i copied your text to the Extensions directory, repaired permissions, and rebooted. But osx keeps telling me that the system extension cannot be used.

Any help would be appreciated.

BTW i have a BCM5754 Gigabit Ethernet PCI Express [14e4:167a] rev 02

THANKS!!!

ive followed your instructions, and i still cannot connect my d620 to the internet with an ethernet wire

any suggestions?

Suggestions? None.
If you'd have D620, AND followed my instructions - You would've got ethernet working in two minutes.

Once again - what's DevID You got there?

Hey A,

sorry for the missing info. i have the same hardware like yours
Vendor ID is 14E4
Dev ID is 1600

I tried chmod, chown, and repair but no dice

sorry, im lost................

@ AA

When I look into at /System/Library/Extensions/IONetworkingFamily.kext with finder I only see a logo brick I was expecting to be able to drill down to /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins but i can not do this.

I have BCM5752 14e4:1600 with ideneb 10.5.5 1.3 with villina kernal.

Can you help?

Also how do i chmod permission? Is it Disk Utility/Repair Permissions?

Thanx in advance Tom

OK. Let's see...

When downloaded this .zip with kext – You need to extract it to some folder. Lets say – folder named Net on Desktop.

1. Double check if you have any kexsts named AppleBCM5751Ethernet in "/System/Library/Extensions". Delete if found any.
2. Open terminal. Enter following command (each line ends with pressing "Enter"):
sudo -s
<Your root password>
cp -r -v ~Desktop/Net/AppleBCM5751Ethernet.kext /S*/L*/E*/IONet*/C*/Plug*/
rm -f /S*/L*/Extensions.mkext
3. Open "Disk Utility" from Utilities, choose system drive and press "Repair permissions"

When all is done – may reboot.

That's all. If nothing's happen – provide Your "gmesg" output.

One more thing: this file suits and reported working ONLY for BCM5752 14e4:1600. But steps to install - are common.

Good luck

thanks for the help and work. I've now got wiredLAN on my d620. I had been watching the hexedit progress over the last 8 months, but no courage to monkey with hex.

I've used the 14e4/1600 5752 kext and it works. For some that have problems, I did also but it seems to have been due to a kernel conflict. I had used iatkosv1 with vanilla kernel. No trouble with iatkosv4. Or maybe it works after install now since I have a fresh os install.

thanks very much, it works good in safe mode, but not in regular mode. it says system extension cannot be used. i tried repairing permissions a few time but still got that message at login...

Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express [14e4:1600] (rev 02)

Hope this helps with the troubleshooting

That's strange...
Can You post Your dmesg output here?
Did You deleted the Extensions.mkext?
To refresh system kext cache try to boot with the -f flag.
Also, would be useful to boot with the -v flag to see system messages while booting.

Can someone please help me with my problem???? Here's a link to my topic (no one has replied to my topic)...I REALLY NEED YOUR HELP. Thanks in advance!!!

the -f flag worked great! Thank you for your help. I can now use my d620 at gigabit speed. I have one more question. It detected the LAN as en2, but en0 still exists. Can i change it so it appears as en0 and not en2? Just a question, dont wnat to seem to particular about it:) Also, will the ethernet still work if connected to a dell docking station? Thanks!

Glad to hear that!


I don't think this is really matters. But, if it bother You – try to delete all ethernet cards from Network preferences, make sure You don't have any of the other ethernet hardware physically attached (also USB, PCMCIA etc.) and reboot. Maybe this helps. Ethernet numbers assigned in the order ethernet hardware appeared in the system.

I think it should. Didn't tried... Sorry.
Also, maybe external mic from dock will work...

ok thanks... since you have D620... there are only two other things that i cant get to work right. was wondering if you had any luck.

1. PMCIA Slot - doesnt work out of the box, and the dell post installation install causes kernal panic.
2. Waking up from screen sleep - The screen always stays black, and i have to restart machine.

Let me know if you had any luck. I care more about getting my screen back from sleep than pmcia slot. Thanks!

For #1 – find latest Chu-Chan's IOPCIFamily kexts.
If you don't install Sigmatel kexts – sleep worked beautifully and vice versa. So #2 for me – just disabled sleep.

I have the sleep issues too, bumer it can not be fixed. Is there any alternative sound kext that might work?

AA I'll try your install instructions for the broadcom tonight. thanx tom

Thanks for the tip. for #2, i have sigmatel kext installed so i guess im out of luck. I disable sleep, and use insomniax, but still fromtime to time, it still goes to sleep, doesnt make sense.

Anyway, i was wondering since your such an expert with ethernet on mac's, can you help me get the following working for a Dell Desktop.

Its a dell precision 390.

BCM5754 Gigabit Ethernet PCI Express [14e4:167a] rev 02

Let me know if you can help, or create the file i need to get it working. Thanks!

You're welcome!
I use a stock power management bundle. With it i don't have a battery meter in menu bar (it's absolutely unimportant for me), but i can set my laptop as "always on", so it don't sleep ever.


You such a flatterer!
(Joking)...
Actually - i'm not an expert. Just an experienced user.

Will try as soon as I get home.
I'll let You know when it's done.

thank you appreciate your help!

Attached kext for You.
Use steps described by me above to install. And don't forget to refresh your kext cache!

Good luck!

NB! for the others: this was made specifically for BCM5754 Gigabit Ethernet PCI Express [14e4:167a].

thanks for all thanks for help!!
but ethernet still not working

here is the missing information...

BCM5906M vendor 14E4 device 1713 subsys 002614C0 rev.02

Hi Loepere, sorry I'm an idiot on hex editing..... Would you tell me which offset and value to edit?
(eg. address 376C0: replace "F8 08 75 59" with "F8 08 74 59")
Thanks alot in advance~~

Thank you for your quick work on this driver. Unfortunately it doesnt work.

I did a dmesg, and here is what i got in reference to that specific kext.

Hope that helps in troubleshooting this issue.

But on a brighter note, thanks to your info my PCCARD slot now works!!!

OK.
We must disable/bypass tha call to NVRam for adapter info.
But this will cause that Your MAC address will not be correctly read from adapter info. And You must set it manually, if this will be the only issue.

If You are familiar with HEX editing software, You can bypass tha call to NVRam it for youserlf.
You need to find address 37554-37555 (75 71) and change it to "EB 71" in kext binary (AppleBCM5751Ethernet.kext/Contents/MacOS/AppleBCM5751Ethernet), then save it and then – put the AppleBCM5751Ethernet.kext back to IONetworkingFamily.kext Plugins folder.

I will do this later, if You are not sure You can make it...

And of course – no warranties at all.

Hey i downloaded hexedit, and did it myself. So now it knows that i have an ethernet connection, i jus thave to manually set the IP Address, which isnt a big deal, and i ASSUME there is no way to fix this. BUt anyway i did run into a problem, if i dont boot osx86 with the -f flag, i will get the system extension cannot be used error. i have ran my repairs and everything, again not a BIG deal, but would like to know if i can fix wihtout having to remmeber to boot with the -f flag. Thanks!

also... i know i ask alot of questions, but you are very good at what you do.

For my d620, the pointing stick and trackpad work, but the trackpad doesn't have two finger support. I have tried the latest dell post installation package... and the trackpad DOES work with two finger support, but then my pointing stick doesnt work, and i seemed to have lost my battery meter and sound. SO i had to revert to the backup kext file to fix it all. just wondering if you have both the pointing stick and trackpad working PROPERLY, and if so how. Thanks buddy! You are an asset to these boards!

Anyone got a good method to get the bcm5788m working? Seen lots of topics but still not a working solution. I have a HP nc2400 laptop.

I finally got Ethernet (BCM5752) working on my D820 thanks to AA.

I had to manually add the Kext to IONetworkingFamily and boot with -F, but it is getting an IP using DHCP.


Just waiting to get my DW 1490 in the mail and I should be good to go.


EDIT - I keep getting an error after reboot saying it can't be used. The only work around I have so far is adding the -f command to the boot.plist. Anyone have any ideas? I had this working before, and then I had to reinstall everything. Never had a problem before.

Thanks A.A.... Works for my Latitude D620 laptop.... its automatically detected as en0 eventhough before this en0 was my usb wireless stick... but i sense its little bit slower when browsing compare when i use usb stick... but who cares..? as long as its functioning.....

Thank a lot...

how about BCM5752M ??? I can't install it Can you help me ?

My Info :

02:00.0 Ethernet controller [0200]: Broadcom Corporation NetXtreme BCM5752M Gigabit Ethernet PCI Express [14e4:1601] (rev 02)

What kind of computer do you have. the 5752 is what I have, and using AA's instructions and kext, I got it working. Although, I have to have the caches rebuilt each boot.

@ techgeekwill : It's IBM Z61m, I tried some kext but I can't do it working

Hi,
can someone do hexedit the driver for me?
NetXtreme BCM5752M Gigabit Ethernet PCI Express [14e4:1601] (rev 02)

Thanks
ralf

I tried with hexedit myself but couldn't find 75 71 at the 37554- address... it only had 00 01

I did search and there was one spot where there is 75 71 so I edited that and funnily now the os x hangs

if you would be kind and post a pre-modified binary it would be great.

In HexEdit options, don't use Decimal Adress

Need help with my BroadCom 5754. I followed the steps of А.Д. but, i don't get connection on my mac. And after reboot, i just get a msg telling this: appleBCM5754Ethernet.kext is Unable to install cuz was installed improperly.. blah blah..

Please, i need help, if someone knows how to install it.. just post it...

Thanks!

Hey ..I think you haven't properly set the driver up, you need to verify the permission .. have you done that ? and the best way to it .is the disk utilities .. not even 3rd party software ...

maybe you want to look on that first ... before you try other solution .

1, verify the permission and see if it work , if not ..then

2, re-do the procedure again, and then verify the permission


have fun ..

Guys,
I have been "fighting" with the Broadcom 5751 driver on my Dell Latitude D410 in the last three/four weeks (On and Off) I installed Kylaway 10.5.2 and the Mac OS can detected my Broadcom 5751 with active connection; however, the MAC Address is a bunch of zeros. I have switched to Manual IP Address and still couldn't get out because my DLink DIR-655 didn't seem to like the Zeros MAC address. The sytem also hang when I tried to enter the MAC using IFCONFIG to add my Mac Addresses
Any idea?
BTW, I found a very sweet "work around" with the $3.99 AirLink101 USB to Ethernet Adapter. I just bought the AirLink USB to Ethernet Adapter this afternoon at my local Fry's Electronics store on Brokaw Road in San Jose, CA. It worked with my Dell Latitude D410/Kalyway 10.5.2 right out of the box no MAC address zero, no driver to mess with. All that for $3.99 (regular price is $14.99 OR HALF of Apple USB to Ethernet Adapter or Wii USB to Ethernet Adapter) This AirLink101 USB to Ethernet Adapter has the newer AX88772 Chip with USB 2.0 interface so it fairly fast. IF you don't want to mess around with the Broadcom driver then this is the way to go for $3.99. IF you don't have local Fry's then try fry.com. They may have it on-line

Hey, do you actaully set your DNS? GATEWAY ?

if you have them set up correctly, I will say that you don't actually need to give an "egg" to what does DLINK like and what it does not.

by the way ..DLINK is the worst router on the market you can find ..not particular to anybody has this brand, so don't be upset if you have one of them

Thanks so much. After having the DELL D820 for two years now I have Ethernet, and CPUs=2 now with XNU kernel. No more shuttering. USB still a bit of a problem looking into it.

I have to have the USB device in the USB slot and reboot so it will see the device.

@ oSxFr33k,

About the USB problem you're having, click on this link to fix it: Solving USB Problems

Most of the time this is caused from having different versions of kernel (mach_kernel) and system.kext. Usually having a 9.2.0 kernel and version 9.2.2 of the system.kext

In the thread you'll find the link to the usb_fix_1.3.mpkg.zip installer file to fix it... it worked wonders for me!

Hope it helps

iSaint

Awesome, works (manual IP and DHCP)
Thank you

now to get video working correctly for core image and quartz extreme and the D830 is 100% for me
