View Full Version : [ubuntu] Rfkill hard block in 9.10 with bcm4301

I can't get wireless working with Lucid Lynx or even Karmic Koala. On occasions I can get it on for a moment, but it'll be soon stopped by rfkill hard block switch. Pushing the wireless on/off button on the laptop does nothing.

Wireless works with 9.04

Same sad problem here, I have a zv5000 series hp notebook.. rf_kill is hardware blocked.

I installed in karmic koala the rfkill packet directly from debian sid, but nothing, the unlock all function doesn't do the magic..

Any suggestions anybody? Please i'm running mad with this wireless b43legacy ](*,)

blacklist the rfkill kernel module

It says I have none module named rfkill in /proc/modules

:(

(i'm looking around and see that many have problems with this issue/button )

Things are working with Ndiswrapper and some loose of time banning b44, ssb and b43legacy modules.. (update-initramfs -u after that)
Yeah! even the beautiful rf button is working good with led too..

now..
Does anybody know please if there is a way to access WPA protected networks with this config?

I'm stuck only with WEP support by now..

Kind regards :confused:

no.. ndiswrapper only needs to load the .inf file located in driver folder downloaded from ...errr.. i don't remeber where.. do a search..

it work but only nosecurity and wep , no wpa or better..

new hope comes from broadcom open release of drivers for wireless chipsets: maybe in 11.04 we would get rid of workarounds :)

ok.. I had the problem with 10.4 and reps to P4man for this;

if
rfkill list
shows a hard block, then try running these, depending on your wifi card type, or something similar;


sudo modprobe -rv ath5k
sudo modprobe acer-wmi
sudo modprobe -v ath5k

hope you get some direection here... :)

That's right. Install the package
$sudo apt-get install rfkill

Then follow the blog http://pkadetiloye.blogspot.com/2010/11/ubuntu-wireless-disabled-siocsifflags.html

Hope that helps!
