Thanks for the reponse Giri. I had a feeling that it
wasn't supported.... I think it's code in the RNDIS
driver that's causing the kenerl panic. I've been
using the same version of ndiswrapper (with a broadcom
PCI card) as the other guy for months without a
problem.

Thanks anyway!

Hi,

Has anyone had any luck getting this work with
ndiswrapper?

I'm currently trying to help someone else get a
Linksys WUSB54GS working.

The inf file for the drivers says that the .sys files
for the XP driver are already in place. When I looked
on an XP system which didn't have the drivers
installed, the files where there. It looks like this
some sort of generic interface for USB NDIS devices.

I got the other person to copy the files from an XP
machine into their ndiswrapper dirver dir and all
seems to work. However, now he's getting fairly
consistant kernel panics.

I've check he's not using 4K stacks, but I don't know
where to go from here. Anyone got any ideas?

Thanks,

G.

Hi,

I' trying to get my Dell Wireless 1450 mini-PCI connected to a Cisco AP
using
LEAP and TKIP with Fedora Core 3 and kernel 2.6.11-1.14_FC3.

The 1450 is found and the drivers install properly:

lspci:
02:03.0 Network controller: Broadcom Corporation BCM4309 802.11a/b/g (rev
03)
02:03.0 Class 0280: 14e4:4324 (rev 03)

modprobe ndiswrapper:
kernel: ndiswrapper version 1.1 loaded (preempt=no,smp=no)
kernel: ndiswrapper: driver bcmwl5a (Broadcom,11/27/2004, 3.100.35.0) loaded
kernel: ACPI: PCI interrupt 0000:02:03.0[A] -> GSI 5 (level, low) -> IRQ 5
kernel: ndiswrapper: using irq 5
kernel: wlan0: ndiswrapper ethernet device 00:11:f5:33:08:eb using driver
bcmwl5a, configuration file 14E4:4324.5.conf
kernel: wlan0: encryption modes supported: WEP, WPA with TKIP, WPA with
AES/CCMP

The authentication is done via Cisco ACS.

iwlist wlan0 scan finds the AP but I'm unable to associate.

I've tried wpa_supplicant as well as xsupplicant without luck.

The wpa_supplicant's config looks like this:
ctrl_interface=/var/run/wpa_supplicant # for wpa_cli support

network={
	ssid="ssid"
	scan_ssid=0
	key_mgmt=WPA-EAP
	group=TKIP
	eap=LEAP
	auth_alg=LEAP OPEN SHARED
	pairwise=TKIP
	identity="userid"
	password="password"
}

eapol_version=1
ap_scan=2

This results in:

# wpa_supplicant -iwlan0 -Dndiswrapper -c/etc/wpa_supplicant.conf -dd

Anyone here having a running config or could shed some light into my issue?

Thank you,

On my laptop, ndiswrapper and the video driver also share the same 
interrupt and I don't have any problems.   The problem could be to do 
with the way the ndiswrapper driver deals with interrupts that aren't 
headed its way or it could be Something Complete Different(tm).   The 
problem could equally well be in the radeon driver.  Generally speaking, 
shared IRQs aren't a problem with PCI devices; they're designed to share 
IRQs.

There are, I think, a couple of things that you can try.   My machine 
has the video and ndiswrapper drivers on IRQ7 probably because I 
disabled the parallel port in the BIOS -- that might've made things move 
around a bit.    I think I also disabled the serial port because I don't 
have it listed although nothing else is using its IRQ.
