Use "lspci -n" and post the line for PCI address 04:00.0. That will indicate the manufactures ID. I think you want to use the iwlwifi driver. Also run "uname -r" to report your kernel version.
Sometimes you simply need to modprobe the driver. Sometimes you need a newer kernel that recognizes the chipset.
Also check your config file for the kernel:
grep -i iwl /boot/config-2.6.34.7-0.7-desktop
CONFIG_IWLWIFI=m
CONFIG_IWLWIFI_DEBUG=y
CONFIG_IWLWIFI_DEBUGFS=y
# CONFIG_IWLWIFI_DEVICE_TRACING is not set
CONFIG_IWLAGN=m
CONFIG_IWL4965=y
CONFIG_IWL5000=y
CONFIG_IWL3945=m
Use the config file for your kernel. The above is the config file for mine.
grep -i iwl /boot/config-2.6.18-128.el5xen
CONFIG_IWLWIFI=m
CONFIG_IWLCORE=m
# CONFIG_IWLWIFI_LEDS is not set
# CONFIG_IWLWIFI_RFKILL is not set
# CONFIG_IWLWIFI_DEBUG is not set
CONFIG_IWLAGN=m
CONFIG_IWLAGN_SPECTRUM_MEASUREMENT=y
# CONFIG_IWLAGN_LEDS is not set
CONFIG_IWL4965=y
CONFIG_IWL5000=y
CONFIG_IWL3945=m
# CONFIG_IWL3945_RFKILL is not set
CONFIG_IWL3945_SPECTRUM_MEASUREMENT=y
# CONFIG_IWL3945_LEDS is not set
# CONFIG_IWL3945_DEBUG is not set
It looks like you need to modprobe iwlagn and iwlcore. Look at lsmod and see if they are loaded.
Is the string "4235" in your iwlagn module? It could be that your device isn't supported by the kernel module for a 2.6.18 kernel.
cfg80211 30793 3 iwlagn,iwlcore,mac80211
iwlagn 94553 0
iwlcore 86853 1 iwlagn
mac80211 137545 2 iwlagn,iwlcore
whenever i try to activate my wifi i got this frustating messages
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
SIOCSIFFLAGS: No such file or directory
Failed to bring up wlan0.

Thanks for your valueable replay jschiwal, yes it detect my wireless access point signal
[output]
# iwlist wlan0 scan
Warning: Driver for device wlan0 recommend version 21 of Wireless Extension,
but has been compiled with version 20, therefore some driver features
may not be available...
