wlan dies after a few minutes

Hi

I'm running Scientific Linux 5 on a toshiba m400 with an intel a/b/g/ wireless card. I'm used ndiswrapper to install the drivers but when I try to activate I get the following message:

Code:

ndiswrapper device wlan0 does not seem to be present, delaying initialization.

googling this hasn't helped me so far.

Information:

Code:

#ndiswrapper -l
w29n51 : driver installed

#ndiswrapper -m

You do not need ndiswapper for the wireless device, remove it. It looks like you already have a good ipw3945 driver installed. Check to see if you have everything needed installed;

rpm -qa | grep ipw3845

You may need to download and install the firmware for the device;

yum install ipw3945-firmware

You will have to reconfigure the wlan0 device for the proper driver, check/edit the /etc/modprobe.conf file.

This makes me think you have a module conflict:

#ndiswrapper -m
module configuration already contains alias directive

What module is aliased for the wireless already? Look in /etc/modules.conf or similar. I suspect your distro includes the native ipw3945 module and is trying to use it instead.

It's probably a better choice in any case.

JasonJensen · 06-04-2007, 09:58 AM

Thanks, I installed ipw3945-firmware and ipw3945 (actually reinstalled the whole system, but that's for another reason)

Anyway, Device Manager shows ipw3945 under info.linux.drvier as it should, but it doesn't show up in Network Configuration.

I figured I could add "alias wlan0 ipw3945" to modprobe.conf, but that just makes it use a nonexisting device.

I know the PCI ID of the device if that's any help.

Hi thanks

my problem eventually evolved (and I couldn't find this thread, believe it or not).
Anyway I started a new thread: http://www.linuxquestions.org/questi...d.php?t=558842

it was also suggested there to not use ndiswrapper, and my last post in that thread explains my current situation. I'd appreciate your help.

You might want to try using the rpmforge-release packages instead.

Uninstall the iwp3945 rpm packages;

rpm -qa | grep ipw3945

rpm -e <see the list from the output above>

Install the rpmforge-release package as per the instructions here;

http://dag.wieers.com/rpm/FAQ.php#B

Then do;

yum install dkms dkms-ipw3945 ipw3945d ipw2945-firmware

To Shadow_7:

Maybe upgrade instead: http://ndiswrapper.sourceforge.net/j...ent/view/16/2/

JasonJensen · 06-04-2007, 12:22 PM

ok I did that, still same problem, only now the device manager doens't have a driver bound to the card.

On that note, wireless worked like a charm in Ubuntu 7.04 so it's not a harware problem.
