Hi. I'm playing around with my N900 to see if I can make it speak with a Nintendo DS. To do this, I'd need to put the wlan0 driver (I'm fairly sure it's called wl12xx) in short preamble mode, but I'm not sure if the driver supports this. It seems it didn't in february 2009 (mail). It also seems it doesn't offer any private ioctls, so I can't play around with iwpriv either.

Does anyone know if the wifi driver supports short preamble, and if so, how I can put it in that mode?

Thanks,
Jonas

i think its missing support yet for it. take a look here:

maybe im mistaken. but just to give u an idea

Hrm, yeah, I've also found that mail, hence why I linked it in the opening post. It seems that mail is mirrored a lot, and some provides timestamps, like this one: http://www.spinics.net/lists/linux-w.../msg28403.html.

The mail is from February 2009, so I figured it could've changed in one of the public releases since then. Anyway, thanks for the reply.

Edit: Oops, looks like I didn't look close enough. After inspecting the source to wl1251.h, there's a define that sets the preamble to long: http://tomoyo.sourceforge.jp/cgi-bin.../wl1251.h#L395.
So I guess one would have to recompile a patched version of the module.
