Hello,

I have an acer asus 3000 with a b43xx wireless nic.
Today I put the laptop into stand-by but, as it frequently happens, it couldn't wake up after that, it would have stayed in an unresponsive state till shut down, so I kept the power button down to force turn off.

When I turned it up again the wifi led didn't turn up and the nic was said to be "turned off". b43 drivers are loaded correctly according to dmesg's log, no apparent software errors.

In the last times it happened I successfully tried the following: keep the entire laptop turned off and without battery for some time (1 night? one day? one week?), change kernel or launch software like wifi-radar.
I'd like to know others' opinion on the matter though, maybe there's something better to do?

TIA

What distro, version, and kernel?

Uh, sorry.
Fedora Core 12, linux 2.32.90*, but it happened with FC12 and FC8 as well, with different kernel versions, and Windows XP as well.

* not sure about the last two digits, I don't have the laptop at hand now.

Not sure with your asus laptop but my dell you can push the fn and f2 buttons at the same time and turn the wireless off and on. I could not make it do it on a hard shut down though.

On my asus I have a separate transparent button, which works as led as well but, just after hard shutdowns, it doesn't work, i.e. the wifi keeps staying down.

Ok, fixed.

*this* time the guilt was... who knows?

I checked the NetworkManager applet and "Enable network" was off, dunno why. I checked the option together with "Enable wireless network", then I defined a wifi-lan with system-config-network and issued
iwconfig wlan1 txpower auto
done.


I did not touch anything before shutting down the computer, so I have no idea on how the configuration could got changed between the sessions..

Well, everything ended well, thanks everybody for the attention!

Here is an article I found with the same problem but not the same os. It sounds like you are losing the ATK driver. I hope this will help without you having to go back to XP.
