Ok, I got some results.
I found on BIOS an option to disable NIC, and I did. Booted to see:

Booted again, enabled and things got very weird.
First, the FN+F2 key started working just as rffill block/unblock. So I
unblocked it.
At start, the network worked for a minute. I thought that all would be
good. But then, NetworkManager told me "wifi connection deactivated".
So I run some tests:

And wlan0 is no more.
More boots, and repetition, gives somewhat near results. Sometimes connect
for a minute, then keeps given errors.
Att,
Beco.
PS. Alternating this problem, I'm still having problems keeping USB wlan2
up. Don't know why. Should be working fine.
NetworkManager is slow. The on/off button keeps an eternity to check.
