Hi
I have been working on getting my bcm5752 ethernet card working
and finally i have met with a small measure of success, but only for a little bit
I am able to recognze the card and connect to the internet for a little bit
but after a minute or two the card dies
The mac address is still showing as all 00:00:00 etc
i was wondering if someone could tell me how to set my mac address and dhcp during the boot process to see if this will help
Thank you in advance
Al

I searched for a solution to this card a few months ago, and never came across a working answer. I know there were some beginning ideas of what to do, but nothing definitive. I wish i had more of an answer, but I haven't mastered the art of programming... sorry.... but i'll search again and if I come across anything...

im not sure if this will work but u can try it, might get u some luck...

i did it on my wireless card and it worked.

sudo nano /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

change en0 to en1
and change integer for the same block of code from 0 to 1

hit Command(Ctrl)+X

and hit enter

restart and go into your network prefs and it should work

let me know if this works

xtreme571,

The 5752 is the NIC, not the wireless card. I had to do what you said to get wireless working for example. From what I remember, the 5750 has been sucessful and there was some positive results for the 5751. The 5752 though...

I got the same story as everyone else with my D620 Centrino/Broadcom 5752:
network works fine for a few seconds then locks up with shutdown dialog. . .

ifconfig reveals my MAC but Network Prefs only got 00's. . .

I even tried adding my MAC address to the Ethernet5751 file directly for an instant lock up. . .

my solution:
boot up with a USB stick and surf from within Linux. . .
