kubuntu 9.04 9.10 10.04 Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01) SIOCSIFFLAGS: Unknown error 132

I don’t know why but with ath5k driver doesn’t work anymore. if i do

sudo ifconfig wlan0 up

i get

SIOCSIFFLAGS: Unknown error 132

so…

SOLUTION WITH ATH5K ***Actually i gotcha …. this freacking wifi card …. well turn off the computer … and disconnect the plug now press the computer’s button which should turn on your computer … that should consume the residual voltage. and now start the pc. this fucking atheros works again with ath5k. WTFuck.****

someone says for a bug in the kernel

well i don’t care. i want it works.

so i have tried madwifi driver. and if you download the standard driver you can got some trouble when you try to compile it.

so this is my personal way. here there is the link to check if you card is supported by madwifi driver

you need of some programs to compile:

subversion (svn) and build essentials

sudo apt-get install subversion build-essential

now you should be able to compile.
**note if you download standard madwifi you could have some trouble compiling them

svn checkout http://svn.madwifi-project.org/madwifi/trunk madwifi ; cd madwifi ; make

** you can do sudo make install if you have not installed checkinstall.

sudo checkinstall

now we must disable the old driver ath5k :

sudo nano /etc/modprobe.d/blacklist.conf

add this

#blacklist ath5k driver
blacklist ath5k

press CTRL X
save and exit.

now we must load the driver : ath_pci

with

sudo modprobe ath_pci

well if you restart the driver will not load on you kernel , everytime you should write sudo modprobe etc etc…

to automatize

kdesudo kate /etc/modules

add the driver , so it will be loaded at the boot time

ath_pci

to check if your system has loaded ath_pci , after the rebooting you should type this

lsmod | grep ath

and you should get ath_pci (ath5k should not appear.)

NOTE FOR KARMIC

when you compile you could get this message

e needs E or Fmake C ./tools all || exit 1

and when you type

sudo make install

your could get some errors… this is bad but if your look well you can still add ath_pci on your kernel…
so just reboot and then use ath_pci like said in this article. here on kubuntu 9.10 tested and it works
