我需要连接的是dlink，有密码。
我在/etc/conf.d/net中设置了
preferred_aps=( "dlink" )
key_dlink="1980***3"
然后建立net.eth1,rc-update -a
可是启动时候好像没有eth1的启动信息。

用手动命令：
#iwconfig eth1 essid dlink key s:1980***3
提示

    SET failed on device eth1 ; Operation not supported.

到底无线网络应该怎么搞，有点郁闷了。

You are using WPA wireless network, "wireless-tools" can not deal with WPA, you should turn to wpa_supplicant, and just follow the guideline.

完全按照上面的做了一遍，问题依旧...

建议使用wpa_supplicant.
方法如下：

#emerge -av wpa_supplicant

#cat /etc/wpa_supplicant/wpa_supplicant.conf：

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
update_config=0
fast_reauth=1
network={
       ssid="TP-LINK"
       psk="123456your password"
       pairwise=TKIP
       group=TKIP
       priority=5
}

#cat /etc/conf.d/net

modules=( "wpa_supplicant" )
wpa_supplicant_eth1="-Dwext"
#config_eth1=( "dhcp" )
#dhcp_eth1="nodns nontp nonis"
config_eth1=( "192.168.1.101 netmask 255.255.255.0 brd 192.168.1.255" )
routes_eth1=( "default via 192.168.1.1" )
depend_eth1() {
        need ipw3945d
}

wpa还是用wpa_supplicant好点，以前我用NetworkManager,很方便，图形化的管理方式，但是最近升级后它能发现网络但是分配不了地址（dhcp），上官网说是要降dhcpcd（大概叫这个)的版本，但是wpa_supplicant就没问题，只不过要敲命令^^

oiniya

用wpa_supplicant配置了一次，还是不能联网。
似乎是密码设置这里有问题。

#wpa_supplicant -Dwext -ieth1 -c/etc/wpa_supplicant/wpa_supplicant.conf

Trying to associate with 00:1b:11:91:20:4e (SSID='dlink' freq=2437 MHz)
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
Associated with 00:1b:11:91:20:4e
WPA: Invalid EAPOL-Key MIC when using TPTK - ignoring TPTK
WPA: Could not verify EAPOL-Key MIC - dropping packet
WPA: 4-Way Handshake failed - pre-shared key may be incorrect
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
Authentication with 00:00:00:00:00:00 timed out.

用NetworkManager的话，可以显示我这边的无线网络，dlink和TP-LINK，dlink是我要连接的网络，路由器设置成了wpa1.0 TPTK,密码是19800603，在windows下使用完全正常。
可是我在NetworkManager下，它总是输入密码，然后连不上，要求输入密码，密码显示的也是wpa TPTK，哪里出问题了？
/etc/wpa_supplicant/wpa_supplicant.conf
network={
  ssid="dlink"
  #proto=WPA
  #key_mgmt=WPA-PSK
  pairwise=TKIP
  group=TKIP
  psk="19800603"
  priority=5
}

再顶一下，看看能不能有解决的方法。

内核中的加密部分一定要编译进内核才能在无线驱动中使用,编译成模块会出错

这个：Could not configure driver to use managed mode是不是说驱动不能被配置为managed mode?
按照手册的说法：Note: If you're using the host-ap driver you will need to put the card in Managed mode before it can be used with wpa_supplicant correctly. You can use iwconfig_eth0="mode managed" to achieve this in /etc/conf.d/net.
是不是要在net文件中加入iwconfig_eth0="mode managed"?
可是我加入以后，提示
