Ubuntu 12.04 'Modprobe ndiswrapper' Command Does Not Work on Asus Laptop


Over the years I've been able to install Ndiswrapper on 4 of my Ubuntu 12.04 machines, 2 desktops, 1 tabletop and 1 laptop, without any trouble. But tonight I failed to add Ndiswrapper to the kernel using the following regular command, which resulted in no errors and no screen output as though it were waiting for something. However, I was able to interrupt the process using CTL+C.

modprobe ndiswrapper

lsmod and modinfo both confirmed the presence of ndiswrapper.

Any help will be greatly appreciated.

Could you explain further. If lsmod shows ndiswrapper then ndiswrapper is loaded.

Normally sudo modprobe ndiswrapper would produce a screen output. But in this particular case, the command was executed but no screen output ensued.

'sudo ndiswrapper -i ' command returns 'couldn't open file or directory' error message

Tonight I unintentionally removed a wireless-network driver named netmw254 through ndisgtk. Ever since then I have been having trouble with ndiswrapper.

If I enter 'sudo ndiswrapper -i netwm254.inf', Ubuntu 12.04 returns 'couldn't open netwm254.inf: No such file or directory at /usr/sbin/ndiswrapper line 162.

(1) Is there an easy way to fix this problem?

(2) If not, how do I totally remove ndiswrapper and then re-install it cleanly from sourceforge.net.

I'll appreciate very much any help from this forum.

Try running:

$ sudo depmod -a
$ sudo modprobe ndiswrapper

Then try checking for errors with:

$ tail /var/log/syslog

it seems to me that the solution to your problem is already in your description:

- you removed netmw254
- some utility complains that it cannot find netmw25.inf

have you tried to find that file and put it back where it belongs?

Hi,

I finally got out of the confusion by re-installing ndiswrapper from sourceforge.net. I was able to install the WN111's driver netmw245 as ndiswrapper declared it installed. Even though I had tried plugging the adapter in the laptop's various USB ports, ndiswrapper failed to see it. Yet lsbusb detected the device every time.

Now I tend to think that this Asus laptop might have a hardware problem. I would like to point out that even when this adapter works on my desktop using the same driver, it can drop out once in a while. It is far inferior to my AE2500 and WUSB54GC adapters. The nice thing about the WUSB54GC is that it works instantly without requiring a driver whether the system is Windows XP or Ubuntu 12.04.

How can I make the WN111 adapter visible to ndiswrapper, the Ubuntu 12.04 Network Manager? Thank you so much for your help.

I finally got ndiswrapper re-installed on this Asus laptop this morning. I've also got the wireless adapter installed and working very well in Windows 7 on the same machine, which tells me that the driver is MRVW24C.sys. So /etc/ndiswrapper/netmw245/ now includes the following files:

07D1:3B10.F.conf
07D1:3B11.F.conf
0846:9000.F.conf
mrvw245.sys
mrvw24c.sys
netmw245.inf

'ndiswrapper -l' reports the following whenever I plug the WN111 adapter into any USB port on the laptop.
netwm245: driver installed
device (0846:9000) present

Yet the adapter fails to light up, Network Manager fails to see it and 'lshw' fails to list it. Naturally 'iwlist scan' and 'ifconfig' show nothing related to it. This means that Linux does not see it and therefore it cannot function. I really don't know where the fault is or understand why the same adpater works in Untuntu 12.04 on my 2004 HP desktop using the same netwm245 driver.

My Asus laptop's WN111's performance is not any better, but at least 'ndiswrapper -l' now reports that the adpater driver is installed and the adpter is truly present no matter which USB port I plug it into.

The adapter is still invisible to Linux and Network Manager as it fails to light up. I've reported in a separate post that this adapter works well in Windows 7 on the same laptop and at least works on another computer in Ubuntu 12.04, using the same netwm245 driver also installed by ndiswrapper.

This is really an enigma to me.

Is this thread just a duplicate of your Ubuntu 12.04 'Modprobe ndiswrapper' Command Does Not Work on Asus Laptop thread?

Thank you very much for the very interesting link.

I do find ar9170-1.fw, ar9170-2.fw and ar9170.fw in /lib/firmware/ on my Ubuntu 12.04 desktop for the WN111v2 adapter (mine is the WN111v1 adapter). But how do I use them in place of the netwm245 driver I've created with Ndiswrapper?

Yes, please excuse me.

Here's my latest input. I've just found an ar9170.fw file in the laptop's /lib/firmware/ driectory. As I understand it is for the WN111v2 adapter but mine is the WN111v1. I think it would be worth my effort to try it out in spite of the version difference.

Can you tell me how to use a .fw file in place of a vendor-provided Windows driver?

Merged your two - ehem - closely related threads. Please stick to one location.
