[gentoo-user] wpc54g card as AP -- works?

[Fernando Meira]

Hi,

I wanted to provide wireless connection to the internet for other laptops at home.
To do this, one laptop is connected via eth0 and wlan0 should work as AP to all others.
I have been following the HOWTO:http://gentoo-wiki.com/HOWTO_Building_a_Wireless_Access_Point_With_Gentoo and trying to find solution in forums... but I can't get it working.
The wireless card is working with ndiswrapper.
When I try to set it to Master, I get this:
# iwconfig wlan0 mode Master
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Invalid argument.

Does this means that the card is unable to perform the task I want, or what am I doing wrong?
Is there any other HOWTO with better instructions? Or anyone that can provide me a step-by-step configuration?

Thanks in advance.
Fernando.
