Wifi always appears disable

Hi,
I flashed bios mod because my wifi module seems like a dead. I bought Intel 4965AGN while 5100 agn is the original. Is a HP dv3530es.

But I can't find any wireless ssid because wifi module appears disable. Into Device Manager on win7 I can see it, then this is recognized.
On Ubuntu is the same. But any OS is able to connect via wifi module

Any ideas?
Thanks in advance
