Thanx for helping

Perhaps instead of using the ieee80211 stack + r8187 driver you could try the mac80211 stack + rtl8187 driver? Provided of course the mac80211 stack is available/compatible with your kernel. Maemo5 has a much newer kernel so it should be do-able.

In my experience both drivers work well with this card, though the r8187 driver works slightly better in monitor/injection mode than the rtl8187 and OTOH the rtl8187 works slightly better in managed/web-browsing mode than the r8187. Yet both are perfectly capable of both managed and monitor mode.

Anyway give the mac80211+rtl8187 route a shot if possible.

The unknown symbols error usually means either it wasn't compiled cleanly or that the driver source needs some moderate (to major) changes in the code to work properly with your kernel.

It's good to hear that usb host-mode is finally working on the N900 (although it's possible that it's the culprit). Oh and you are providing the card adequate external power, yes?

This is just the insmod phase so power isn't an issue yet... but it will be of course.

The messages you are getting should be warnings according to the wiki, but there is also a fix there too:

http://www.aircrack-ng.org/doku.php?id=r8187

When I was using this driver, it was with n810, so an older/different kernel. But I used ieee rather than mac and it worked fine. The mac approach is worth testing though, just another data point.

You are 100% correct
I wont say im not interested about injection rates , but for now it will be great to have it just working.

I compiled module from kernel-power-2.6.28...
Im not 100% sure i've it correcly so here is what i did.

1. from scratchbox i downloaded kernel source:
[sbox-MaemoKernel: ~/maemo_kernel] > apt-get source kernel-power

2. I entered kernel-power folder and copied default config:
[sbox-MaemoKernel: ~/maemo_kernel/kernel-power-2.6.28] > cp debian/rx51power_defconfig arch/arm/configs/
[sbox-MaemoKernel: ~/maemo_kernel/kernel-power-2.6.28] > make EXTRAVERSION=$(dpkg-parsechangelog | sed -ne 's/^Version: .*-maemo\(.*\)/.10power\1/p') rx51power_defconfig

3. I edited .config and discomented "CONFIG_RTL8187 is not set" to "CONFIG_RTL8187=m" i think its a good idea to compile it as module:
#
# Wireless LAN
#
# CONFIG_WLAN_PRE80211 is not set
CONFIG_WLAN_80211=y
# CONFIG_LIBERTAS is not set
# CONFIG_LIBERTAS_THINFIRM is not set
# CONFIG_USB_ZD1201 is not set
# CONFIG_USB_NET_RNDIS_WLAN is not set
CONFIG_RTL8187=m
# CONFIG_MAC80211_HWSIM is not set (im not sure if its necesary, i think not)

4. Including changes for compilation.
[sbox-MaemoKernel: ~/maemo_kernel/kernel-power-2.6.28] > make EXTRAVERSION=$(dpkg-parsechangelog | sed -ne 's/^Version: .*-maemo\(.*\)/.10power\1/p') oldconfig

5. Compiling modules
[sbox-MaemoKernel: ~/maemo_kernel/kernel-power-2.6.28] > make EXTRAVERSION=$(dpkg-parsechangelog | sed -ne 's/^Version: .*-maemo\(.*\)/.10power\1/p') modules

Once compiled i took the module apart and tried to insmod it, here is dmesg output:
[ 9536.131896] rtl8187: no symbol version for struct_module

I have not provide any external power source such as a powered hub, i think h-e-n provides itself enough power, anyway i will try one.

Thanx for helping

what kernel do you have on your n900 ?

2.6.28.10power46

you compiled the driver without errors ?
when i tried the screen fill with errors like chickenpox.

The legacy drivers use the ieee80211 or net80211 stacks
keep in mind kpower46 already have mac80211 so you must adapt rtl driver for mac80...

blacklist ieee80211 for peace of mind

you can put EXTRAVERSION=".10power46"
try once more.

Legacy rtl8187 use net80211 witch is included by default in the stock and power kernels, so i thought it sould just work.

Source: http://www.aircrack-ng.org/doku.php?...869cc901b6514f

I compiled just the modules not the entire kernel and copied the rtl8187 module to /lib/modules/2.6.28.10power10/ at N900 and tried to insmod it.
No luck so far.
When i edited the config i was whiling to find CONFIG_RTL8187_LEDS option too but it was not present, anyway CONFIG_WLAN_80211=y was set

If you do lsmod | grep ieee will see there's no ieee80211 module loaded.
mac80211 is loaded by the built in wifi card module wl12xx.

I had always work with rtl8187 included at kernels (2.6.27 and newer) for browsing and compiled r8187 for monitor/injection task at debian without problems.

Hey guys, i've got r8187 compiled and insmoded ok

Tryed once again compiling r8187 and trying to understand every step i was doing

Thanks paulkoan for this tip

Ok, here are the steps i did so anyone can build it:

1. at scratchbox download the rtl8187 source
wget http://dl.aircrack-ng.org/drivers/rt...ux_26.1010.zip

2. Unzip and enter source folder
unzip rtl8187_linux_26.1010.zip
cd rtl8187_linux_26.1010.0622.2006/

3. Download patch
wget http://patches.aircrack-ng.org/rtl8187_2.6.27.patch

4. Unpack driver and stack
tar xzf drv.tar.gz
tar xzf stack.tar.gz

5. apply the new patch:
patch -Np1 -i rtl8187_2.6.27.patch

6. edit ./beta-8187/r8187.h
change the line:
#include <asm/semaphore.h>
to:
#include <linux/semaphore.h>

7.edit ./beta-8187/Makefile
change the line:
EXTRA_CFLAGS += -mhard-float -DCONFIG_FORCE_HARD_FLOAT=y
to:
EXTRA_CFLAGS += -msoft-float -DCONFIG_FORCE_HARD_FLOAT=n
(Thanx to qwerty12)

8. Compile stack against kernel-power-headers
make -C /usr/src/kernel-power-headers/ M=/targets/FREMANTLE_ARMEL/usr/src/rtl8187_linux_26.1010.0622.2006/ieee80211/ modules

9. Remove ./beta-r817/Module.symvers and link the one at the folder ieee80211:
rm -f ./beta-8187/Module.symvers
ln -s ../ieee80211/Module.symvers ./beta-8187Module.symvers
(Thanxs to paulkoal)

10. Compile driver against kernel-power-headers
make -C /usr/src/kernel-power-headers/ M=/targets/FREMANTLE_ARMEL/usr/src/rtl8187_linux_26.1010.0622.2006/beta-8187/ modules

Note: If its fails saying it needs ECHI KERNEL SUPPORT remove lines referencing this at ./beta-8187/r8187_core.c
(Thanx qwerty12)

11. Copy modules to your N900, rmmod modules for wifi and mac80211 stack and insmod new modules in sequence.
rmmod wl12xx
rmmod mac80211
insmod /path.to.your.modules/ieee8011_crypt-rtl.ko
insmod /path.to.your.modules/ieee8011_crypt_wep-rtl.ko
insmod /path.to.your.modules/ieee8011_crypt_tkip-rtl.ko
insmod /path.to.your.modules/ieee8011_crypt_ccmp-rtl.ko
insmod /path.to.your.modules/r8187.ko

You are done.
