LinuxQuestions.org - Cannot connect to ad-hoc WiFi

I'm trying to set-up wireless network between my Gentoo PC and Windows XP laptop

I've succeeded to install drivers, start wlan0 NIC, iwlist wlan0 scanning shows surrounding networks. Gentoo PC is set to be ad-hoc master, my laptop able to find it's network but cannot connect to it.
I tried to use both static and DHCP ip addresses but neither worked.

Im using the following:

wireless-tools
wpa_supplicant
Drivers taken from b43-fwcutter

Code:

# lspci -vnn

01:06.0 Network controller [0280]: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)

Subsystem: ASUSTeK Computer Inc. Device [1043:100f]

Flags: bus master, fast devsel, latency 64, IRQ 18

Memory at fddfc000 (32-bit, non-prefetchable) [size=8K]

Kernel driver in use: b43-pci-bridge

A piece of /etc/conf.d/net describing my wlan0:

Code:

modules=( "iwconfig" )



key_FALCON1="[1] s:************* key [1] enc open"

preferred_aps=( "FALCON1" )



adhoc_essid_wlan0="Falcon"



mode_wlan0="ad-hoc"



config_wlan0=("192.168.150.3 netmask 255.255.255.0 brd 192.168.150.255")



# Set the ESSID of the interface

# In managed mode, this forces the interface to try and connect to the

# specified ESSID and nothing else

essid_wlan0="Falcon"



# We use channel 3 if you don't specify one

channel_wlan0="8"

Any ideas?
