I have installed openSUSE 11.3 in my old compaq Presario V3026TU machine which has the Intel PRO/WIRELESS 3945ABG WLAN card. Yast can detect the network card. But I cant make it work in any way. The switch to manually on-off the wireless doesnt work (the LED never become active).
The “ifconfig” does not show the wireless interface, but “ifconfig -a” and “iwconfig” show the wlan0 interface.
One more thing to mention, during my installation and while I run on live cd, the wireless becomes active. But after installation, I am facing this problem.
I used openSUSE 11.1, Ubuntu and Fedora and I never faced this problem before. Does anyone know any solution?
If it’s working in the live cd it should definitely work on the installed version. You should collect all the data from the live environment and compare to see what’s different. The sticky posts here show all the commands to find out the relative information, such as…
lsusb
lspci -nnk
uname -r
dmesg | grep firmware
You should also check wether your installed environment is using network manager or ifup (traditional method).
I apologize, the live CD I used was OpenSUSE 11.1. But I am providing some information which may be helpful for identifying the problem.
I have been using openSUSE 11.3 for about 3 months. When I first install this OS, everything was working fine. Suddenly one morning, i found that my wireless LED is not working and the wireless device too. I tried to make it work using ifup, restart etc… But nothing worked. Then I tried with live CD that I have with me. But I forgot to check the OpenSUSE version… Sorry for this.
The thing is If I type “ifconfig”, the wlan0 is not showing. But if I use “ifconfig -a”, my wireless device is showing.
The creating a new user does not work. Actually when I turn on the wireless device physicall, the LED does not change. But the same thing works on open suse 11.1 or ubuntu.
Yes. Before using openSUSE 11.3, I have been using ubuntu (8.1 -10.04 upgraded one by one) and everything was working fine. Couple of months ago, I installed openSUSE 11.3.
I thought there is problem with my wireless card. Then I tried with live cd of openSUSE 11.1. In that case I found that, my wireless card does not activate after booting. I need to “switch off and on” to activate it.

So something is wrong somewhere.
Because as I say, I have this device on my R61 and it works fine.
How you solve this is dependant on the extent to which you are prepared to go.
When I first install openSUSE 11.3 in June 2010, everything worked fine. Suddenly one morning I found that, my wireless device becomes inactive and I could not activate it. I reinstall the OS and got the same result. I have been using Ubuntu 10.04 before. So I thought that may be my wireless device has some problem. I install ubuntu 10.04 and saw everything is fine. Then I tried with openSUSE 11.1 live cd and found it functional. But for openSUSE 11.1 the wireless device does not activate just after boot. I have to manually swith off and switch on the wireless device. After that it works fine.
Now I failed in all the way for openSUSE 11.3. The device show when I type “ifconfig -a” but it does not show if I type “ifconfig”.
In my notebook there is no option in the BIOS for enable or disable wireless card. But there is a switch which can switch on and off of the physical device and it is not working for openSUSE 11.3.
if I manually down the wireless card typing “ifdown wlan0”, I get the following output:

Does the output of the dmesg command say anything about the RFKILL or radio
switch. Some laptops have a real on/off slide switch and do not require any
additional drivers. My HP has this kind. If yours has a pushbutton, then you
need the wmi (Windows Management Interface) driver for your brand. As you have a
Compaq, yours should be called hp-wmi. If the command ‘lsmod | grep wmi’ returns
nothing, that driver is not loaded.
It is also possible that your laptop is not handled by the current version of
hp-wmi. Note that Linux did not honor the radio switch on most models until
2.6.32 or later kernels. Thus openSUSE 11.3 is the first release affected by
this safety feature.
“dmesg” doesnt say anything about RFKILL or radio switch. But “lsmod | grep wmi” provides hp_wmi 5882 0
wmi 7467 1 hp_wmi
rfkill 17298 2 hp_wmi,cfg80211
One thing is to mention that, my wireless card stop working suddenly. As I mentioned in my earlier post that, I have reinstalled my openSUSE from a DVD, but does not work.

Post you dmesg output at pastebin or some similar location and give us the URL.

Nothing unusual except for the fact that your wired connection is running. With
recent versions of NetworkManager, it will only use wired if the wire is
connected. For it to even try a wireless connection, the wire must be disconnected.
