BCM4318 (rev 02) not working on Snow Leopard

Yep solved it - embarrassingl; I just had to get a stronger power supply unit.

@teqtonixyou had to replace the power supply for you computer.. and it just worked?

Well basically yes as I was still using some 350W ATX 2.0 one (20 Pin Mobo supply on 24 Pin board) - what must have been the main reason for my wifi card not to work. I just had that idea, when I was trying to set up the wifi on Linux without having the kernel module beeing loaded, alltough the firmware was present in /lib

@teqtonixThere was something wrong with my DSDT.aml I replaced it with a different one and now everything is working fine.

I can confirm that. The BCM4318 PCI NIC for some reason works only without having Device (HPET) in DSDT… Wherefore I am currently either without having Speedstep & Sleep or without having wireless :-| (If someone has an idea / is able to fix that - let me know...) - but I haven't realy thaught about that issue in your case - sorry about that...

Nice to see you here & thanks for your response.

But well this does no longer realy matter to me, since one of the carriers droped the box with my Gigabyte/Intel rig, when I was moving to a new place, about a week ago.
Since that I am back on the AMD side of life & hey everythings working fine & smoothly...

Thank god I was collecting all the bills, so I am going to get my iPad next month using the insurance sum I received. :

Same problem

Did you happen to find a solution to the bcm4318 problem. I have tried everything and I just can't figure it out.

?

you had to replace the power supply for you computer.. and it just worked? : Sorry I've been running Leopard on my Dell for the past 2 years, and I can usually trouble shoot problems and solve them on my own.. but what does replacing the power supply have to do with the OS not recognizing the wireless card? I'm confused now.

Sorry for all the questions,

Thanks again for the help.

Fixed it

There was something wrong with my DSDT.aml I replaced it with a different one and now everything is working fine.

I have HPET fixed in my dsdt along with a few other fixes, just wanted to post that under 10.6.3 My Dynex PCI Wifi Card is working
