wireless network is always down

hi!
my wireles configuration can be found on another post
http://bbs.archlinux.org/viewtopic.php?id=32503

everything was working fine until some weeks ago, everytime i try to connect to the wireless network, it does not work.
chipset is BCM4303 (say lspci and hwd, though in the past one was saying BCM4301 and the other BCM4303), and I use the b43legacy module. the problem is that now, whenever I try to scan for an AP (either with iwlist or wpa_supplicant), I get the answer that the network is down.
The first command I use are:
iwconfig wlan0 essid eduroam
ifconfig wlan0 up
then, when I try wpa_supplicant or iwlist scan wlan0, I got the mssage that the network is down.
If I try to bring it up again (ifconfig wlan0 up), i got the message:
SIOCSIFFLAGS: Unknown error 132.

I tried to reinstall the firmware but it was pointless.
any help?

Re: wireless network is always down

ok, now i figured out, with the help of rfkill, that the issue is there is a hard block on the wireless lan, but that only happens when i try

ifconfig wlan0 up

without bringing wlan0 up with ifconfig, i'm unable to scan for APs nor to connect to any

Re: wireless network is always down

the thing is, when i bring wlan0 up with ifconfig, the hardblock on the wireless lan is brought from no to yes, and then if i try to look for an AP (iwlist wlan0 scan), i got the message that the interface does not support scanning.

Re: wireless network is always down
