I am trying an experiment with my Atrix in which I need to be able to build the kernel and have a working wifi module. I have successfully built the faux123's kernel-MB860 (thanks very much!).

I then downloaded faux123's atrix-wifi-module in order to get wifi working. I have built the module, and pushed it to /system/lib/modules. However, wifi doesn't work. Under settings, it just displays "error". dmesg doesn't show nearly as much as a kernel packaged by faux123. Here is my output:

If I try to do a insmod, I get an invalid argument message.
# insmod /system/lib/modules/dhd.ko
insmod: init_module '/system/lib/modules/dhd.ko' failed (Invalid argument)
Can someone suggest what I might be missing or doing wrong?

as far as i've researched this problem, it's hardware related. i get the same error (and an accompanying reboot) every time i try to toggle wifi.

if you have any more success please let me know.

I'm not convinced it is hardware related (other than maybe having the wrong driver), since wifi works great using a true faux123 kernel/module.

I suspect my problem has something to do with how I compiled module or other files that I need to put on the phone.

How did you build it? A little more background might help

Talking Build process ... it works!?!?
First, the good news...the module now works. But I don't understand what I may have done differently this time other than do the builds consecutively.

I retrieved the source:
$ cd ~/android/faux123-olympus-cm7-kernel
$ git clone
$ cd ~/android
$ git clone
Then I built:
$ cd ~/android/faux123-olympus-cm7-kernel/kernel-MB860
$ make ARCH=arm tegra_olympus_cm7_defconfig
$ make ARCH=arm CROSS_COMPILE=/home/kenny/tools/arm-2011.09/bin/arm-none-eabi- -j1

$ cd ../../atrix-wifi-module/open-src/src/dhd/linux/
$ export LINUXSRCDIR=/home/kenny/android/faux123-olympus-cm7-kernel/kernel-MB860
$ make ARCH=arm CROSS_COMPILE=~/tools/arm-2011.09/bin/arm-none-eabi- -j1
$  adb push /home/kenny/android/faux123-olympus-cm7-kernel/kernel-MB860/vendor/bcm/wlan/osrc/open-src/src/dhd/linux/dhd.ko /system/lib/modules/dhd.ko
I had kernel built a few days before I had found the wifi module source. I then tried building the wifi module and pushing the module as shown above.

Since then (over last week or so), I have tried a number of things, including copying files (/etc/firmware/wifi/*) from another phone which has a faux123 kernel. Are these files required? Are there steps in here that I missed?
