1. Get a copy of the source for ndiswrapper 1.56 - http://sourceforge.net/projects/ndiswrapper/files/
2. Get a copy of the wireless drivers for Broadcom bcm43xx based devices - I have attached a copy. Yes this is for Netgear WNA3100, but the Broadcom chipset is present.
3. Extract ndiswrapper, cd to driver, and make this addition to ntoskernel_io.c (or just download from attachment) - http://matthew-4gl.wikispaces.com/wna3100_ubuntu_linux ** NOTE ** The reason for this is because the driver listed on that page uses the symbol IoUnregisterPlugPlayNotification, which must be added to ntoskernel_io.c. I ended up using the driver attached and not the one listed on that page. It is possible that this step is not necessary with the attached driver, but it will not hurt. Any input would be appreciated.
4. At this point, the link listed in step 3 suggests to make/make install, but our kernels do not support some of the code in the ndiswrapper build. Apply these changes to loader.c, wrapndis.c, and usb.c (or just download from attachment): viewtopic.php?f=53&t=74793#p435023 ** NOTE ** The two patches here, for whatever reason, did not work for me. I had to hand edit the code using the suggested patches as a guideline.
5. Additionally, I had to make these changes to wrapndis.c to get things to compile - basically, just shuffling around the #include order - http://chakra-project.org/bbs/viewtopic ... 450#p28450
6. This is where I think those of us who are using 64-bit Mint have to deviate a bit. Following steps I had found on the net, after adding my driver to ndiswrapper, I would get a rather lengthy error after plugging in my network device relating to USBD_InterfaceIsDeviceHighSpeed. Full text of error here: http://ubuntuforums.org/showthread.php?t=1773140. Assuming your have high speed USB (I guess this is what this function is trying to determine?), make another additional change to usb.c - or download attached file:
- Code: Select all
wstdcall BOOLEAN USBD_InterfaceIsDeviceHighSpeed(void *context)
{
struct wrap_device *wd = context;
USBTRACE("wd: %p", wd);
if (wd->usb.udev->speed == USB_SPEED_HIGH)
USBEXIT(return TRUE);
else
USBEXIT(return FALSE);
}
becomes
- Code: Select all
wstdcall BOOLEAN USBD_InterfaceIsDeviceHighSpeed(void *context)
{
/*struct wrap_device *wd = context;
USBTRACE("wd: %p", wd);
if (wd->usb.udev->speed == USB_SPEED_HIGH)
USBEXIT(return TRUE);
else
USBEXIT(return FALSE);*/
USBEXIT(return TRUE);
}
I imagine the problem is in casting context to type wrap_device, but my C skills are a bit rusty. Any insight here would be great - or better yet, a solution that will actually check to see if the interface is high speed and return true or false, but actually work
7. In the ndiswrapper directory, in a terminal, do "sudo make", then "sudo make install".
8. Unsure if this step is necessary, but I noticed the module builds to /lib/modules/misc/ndiswrapper.ko, but "ndiswrapper -v" reports the module is installed at /lib/modules/2.6.38-8-generic/kernel/ubuntu/ndiswrapper/ndiswrapper.ko. I renamed the latter to ndiswrapper.ko.old and copied the other into this location.
9. At this point I rebooted since I had just created a new module, again, unsure if this is necessary (I admit I'm a bit of a Linux noob). Go to where you extracted the Broadcom drivers, and run "ndiswrapper -i bcmn43xx64.inf". If you get permission errors run "sudo" first. Plug in your device, and hope for the best. After plugging in the device, the results of "ndiswrapper -l" should be:
- Code: Select all
bcmn43xx64 : driver installed
device (0846:9020) present
And your network icon in the tray by the clock should start to spin as it looks for networks.
I hope this helps somebody not have to spend many hours on this like I have. If anybody has any input please let me know and I will make the appropriate edits.
