Hi, I'm new at the community. I have a problem with the ethernet port on my MacBook Pro 13 (year 2011), wich I beleve is a Broadcom Netxtreme Gigabit Ethernet (model 5764). The problem is that it wont work in Mac OS X Snow Leopard 10.6.8 (it allways show a "cable unpluged" status), while it works perfectly on my bootcamp partition. So, it is not a hardware issue. This only started to happen a few days ago, it worked perfect until that time.

When I open a terminal window and type "ifconfig en0 up" it returns "interface en0 does not exist" and when I type only "ifconfig" it doesnt show in the list, while airport and firewire shows fine. In Safe Mode I get the same results. I've tryied to find a new kext for the broadcom 5764, but I couldnt find it.

I've tryied and searched a lot. But I cannot get it work. Yersterday I rebooted with the Mac OS Installation disk and it recogniced my ethernet (en0) interface. Went back to Mac OS and it worked perfectly for the day. But today it doesnt work again, and I cant solve it like yesterday, it's useless even when Mac OS Installation still recognices my ethernet interface.


So, any ideas?

Thank yoou for reading

MacBook Pro, Mac OS X (10.6.8)
