Get a network problem when install

Hi
I gotta a problem when installing gentoo on my laptop. When I net-setup eth0 normally but it cannot bring up the wireless network.
Firstly I've checked ifconfig eth0 output which seems to be alright except one interrupt:19 at last line that I'm not quite sure about. But I can never ping to any IP address even my own router! I'm wondering if the problem should be blame to the wireless env or anything else

thx

Since this is an install, you can't really recompile you kernel. Your kernel is part of the CD. Try using a different CD. I would use the system rescue CD since its gentoo based and has X.

Well much appreciated for your advice all. And I just got a cabel to start my install. But I still cannot bring up wlan0 after the successful install. Whatever I've tried with wpa_supplicant it always prints "Could not read interface wlan0 flags: No such device" and there's no wlan device in ifconfig despite that I've include the wireless driver when compiling kernel. I'm wondering why and how..
Thx

You need to enable CONFIG_IWLWIFI or CONFIG_IWLAGN (depending on kernel version), and emerge iwl5000-ucode

As you've told me I successfully brought up the wlan0. But due to the coexistance with windows xp I got to redistribute the harddriver. Then there goes like a disaster with wpa_supplicant.
My wifi network is set WPA2/TKIP encrypted while it always prints invalid EAPOL-Key. Therefore I changed my routes settings as WPA/AES and my configuration file:

I'm suspecting the reason is due to kernel which doesn't provide correct algorithm for the 4-way shakehand. But I did compile the net-gen intel wifi driver and cfg80211 as built-in. Also I've emerged iwl5000-ucode. Thus I cannot figure out where the problem is...
Thanks
