problems w/ Linksys WUSB54Gv4 & ndiswrapper on sid

Ahoy,

I apologize for posing this twice but it sank to the botom like a rock in the ocean on the hardware forums and i desperatley need this up.

I'm running sid, w/ kernel 2.6.8-2, I've installed packages ndiswrapper-modules-2.6.8-2-686_1.1-2_i386 and ndiswrapper-utils_1.1-4_i386 I downloaded the windows drivers for this thing from the linksys site and then ran

Code:

ndiswrapper -i rt2500usb.inf

it installs succesfully and when i run

Code:

ndiswrapper -l

it says

Code:

rt2500usb          driver present, harware present

now the problem is that when i run

Code:

modprobe ndiswrapper

it gives me the following error and the program hangs ( the system is fine and i can use it by switching into another tty) and most importantly the adapter doesn't work

Here's the error

Code:

ndiswrapper version 1.1 loaded (preempt=yes,smp=no)
ndiswrapper: driver rt2500usb (Linksys,01/07/2005, 2.00.00.0000) loaded

Google hasn't been much help.

Any ideas?

Hi there,

If I was faced with this situation I'd try using a later kernel, even a 2.6.11 if I could get my hands on one. I dont think this is an ndiswrapper problem, judging from the error it spat out in your post. In fact, having read it again (and seeing the "oops" in about the fourth line or so) I'd definitely take this route. I think everything else you are doing is correct and is acting as its supposed to.

Chris

Hi,

I ran into the same problem (using sid - kernel 2.6.10., wusb54g and ndiswrapper 1.1).
It worked with an older driver (the one that was shipped on the CD) and unloading ehci (it would be great if anyone could explain to me, why it works this way ,)).

In the "ifconfig" listing the device shows up as wlan0 and I'm able to connect to a wlan now.

I'm nevertheless not able to put it into monitor mode, can someone help me?

Thanks

Grabitz

P.S.
I will try the new kernel version

I wasnt aware that card supported monitor mode - have you verified this as not all cards do - it is not part of the 802.11 standard you see.

Well, I guess ill install 2.6.11 and compile the ndiswrapper module for it then,
Will report back and tell you how that goes
