wireless connectivity issues
 

Hi all,

I am a linux new-bie. I have installed fedora 9 on my dell XPS laptop. I am able to connect to internet through ethernet. But i cannot connect through wireless. I thought reason may be that its missing drivers for the wireless card but on research i found that my kernel version should already have the required drivers.

FYI,
command 'uname -a' returns,
Linux localhost.localdomain 2.6.26.6-79.fc9.x86_64 #1 SMP Fri Oct 17 14:20:33 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

and command 'lspci' returns my wireless card as:
Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

'/sbin/ifup wlan0' returns

Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument.

Determining IP information for wlan0...SIOCSIFFLAGS: No such file or directory
SIOCSIFFLAGS: No such file or directory

Can someone tell me where should i start to solve this problem. Thanks a lot,

Gaurav

Unload then reload the driver.
Then view the messages ...You should have some output at the end concerning the driver, this will assist us in figuring out the problem.

Thanks dxqcanada.
'dmesg | grep iwl' gives me

Looks like there is some problem with Firmware. Do i need to install some firmware? Any idea whats happening?

Thanks,
Gaurav

Yes, you need install the firmware file.
I think the package is called iwl3945-firmware.

As I do not use Fedora, I am going to guess that you would use yum to install it ... and that it will put the firmware in the correct directory.

here i solve my first linux problem .. Thanks to you dxqcanada ..

its seems that i have the same trouble but i think im more than a newbie...

i have an atheros 242x. looks like it was running lastnight but today i just cannot connect to my wireless.

Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

my kernel is

Linux localhost.localdomain 2.6.27.9-73.fc9.i686 #1 SMP Tue Dec 16 15:25:05 EST 2008 i686 i686 i386 GNU/Linux

and i try to set up my wireless card (in a gui mode) and i cannot do it.

i tried command line mode ... and i get ...
[root@localhost H34V3N]# ifconfig wlan0 up
SIOCSIFFLAGS:resource unavailable temporarily

the thing is that i can connect eth0 and lastnight it was working just fine.

i dont know what happend or what im doing wrong, please assistance...

Did you resolve this? I say this because I notice your CLI ifconfig stated "resources unavailable temporarily" It may be when you rebooted later it will have been resolved.

I'm a newbie too and some of your comments confused me. To me eth0 is an Ethernet cable connection not wifi.

Try iwconfig without any parameters. Mine shows no wireless connections for (lo) (eth0) and (wlan) but a wireless connection for (ath0) which is my
wireless driver of my NIC also.

My wireless card driver configuration
 

I have an atheros 242x on my laptop running linux suse 11.0.
Linux recognise my wireless card, but does not have its driver. I learnt that i have to use madwifi,but no to avail.

Under the network settings in YAST...
AR242x 802.11abg Wireless PCI Express Adapter (Not connected)
BusID : 0000:03:00.0
Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details.

I typed onto the command prompt, 'uname -a' and it gave me:
Linux linux-ckay 2.6.25.5-1.1-pae #1 SMP 2008-06-07 01:55:22 +0200 i686 athlon i386 GNU/Linux

I also typed 'dmesg' on the cmd prompt and displays:
SPT=5353 DPT=5353 LEN=56
SFW2-INext-DROP-DEFLT IN=eth0 OUT= MAC=01:00:5e:00:00:fb:00:16:d4:94:3d:c2:08:00 SRC=10.2.2.8 DST=224.0.0.251 LEN=76 TOS=0x00 PREC=0x00 TTL=255 ID=27 PROTO=UDP ...blah blah blah....

I need serious help pls someone anyone....HELP!!!!!!!!!
I'm new to linuxish.

You have a bit of a catch 22 situation because to resolve your problem you need access to the web.

If you can't do it find a friend who can access http://www.madwifi.org and download the following file madwifi-hal-0.10.5.6-current.tar.gz.

They could email it to you. Put it in your Home directory and then do the following in a terminal.

tar zxvf madwifi-hal-0.10-5.6-current.tar.gz

This will open the archive in a new directory madwifi-hal-0.10.5.6-r3861-20080903; go into this directory e.g
cd madwifi-hal-0.10.5.6-r3861-20080903/

and type the following.
make

(for the next bit you have to be root) so
su(password)make install
modprobe ath_pci

You must have the headers for your kernel installed for this to compile.

Hope you are successful

everycase is different
 

thank you grabpro for your comments, i spend almost an afternoon looking for a solution and i found out ... misteriosly... du..du.. du .. duuuhhhh...
