参考
http://www.sxnsx.com/wireless-networ...abg-on-gentoo/

http://en.gentoo-wiki.com/wiki/Speed_Up_Boot_With_Wicd

我的能启动，但是没测试过没环境，主要是内核
然后
emerge -av net-wireless/iwl3945-ucode

以及使用wicd管理网络
很多人都成功了，你试下看看，记得内核要配置好。

作者: chenhaolost 发布时间: 2009-09-27

恩，正在搞内核，刚刚看了wiki上面发现有些选项没选。
Wicd 这个好像要gtk的，我USE="-gtk"，好像用不了，上次装了，启动不了，要么就是我无线网卡没启动，无法用这个软件管理。

wicd还是有点问题

代码:

T ~ # wicd-client
Traceback (most recent call last):
 File "/usr/lib/wicd/wicd-client.py", line 38, in <module>
 import gtk
ImportError: No module named gtk

估计你是用KDE的，看下KDE环境下的无线管理软件吧，我是gnome用户，对kde不是很清楚。

刚刚发现 /etc/conf.d/net 文件有点错，呵呵.刚刚改过来，

代码:

GT ~ # cat /etc/conf.d/net
# This blank configuration will automatically use DHCP for any net.*
# scripts in /etc/init.d. To create a more complete configuration,
# please review /etc/conf.d/net.example and save your configuration
# in /etc/conf.d/net (this file :]!).

config_eth0=("10.20.37.77/8")
routes_eth0=("default via 10.20.37.254")

modules_wlan0=( "!iwconfig" "wpa_supplicant" )
wpa_supplicant_wlan0="-Dwext"
config_wlan0=("dhcp")
dhcpcd_wlan0="-t 10"
dhcp_wlan0="release nodns "

代码:

GT ~ # /etc/init.d/net.wlan0 start
 * Caching service dependencies ... [ ok ]
 * Starting wlan0
 * Loading networking modules for wlan0
 * modules: adsl apipa arping tuntap bridge ccwgroup macchanger macnet rename wpa_supplicant essidnet iptunnel ifconfig pppd system dhcpcd ip6to4

貌似启动了，wifi的指示灯也亮了，但是kwifimanager的 Adapter还是空的，

问个问题，要想wifi工作，用的是wap_supplicant，要配置的文件有哪些？谢谢，我的系统没有/etc/wpa_supplicant/wpa_supplicant.conf 这个文件，是否需要自己建立？
