Gateway W350l
无线网卡型号
Intel(R) RRO/Wireless 3945ABG Network Connection[sunshine@MagicLinux ~]$ lspci | grep 3945
04:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)其实这个网卡在2.6.29的内核中就已经包含了,因此内核中需要有驱动
[sunshine@MagicLinux ~]$ lsmod | grep 3945
iwl3945               145712 0
iwlcore               163216 1 iwl3945
mac80211              166664 2 iwl3945,iwlcore
led_class               4080 2 iwl3945,iwlcore
lib80211                6416 2 iwl3945,iwlcore
cfg80211               64972 3 iwl3945,iwlcore,mac80211然后安装firmware: iwlwifi-3945-2.ucode 和一个守护程序:/sbin/ipw3945d
http://intellinuxwireless.org/iwlwifi/downloads/iwlwifi-3945-ucode-15.32.2.9.tgz内核加载 iwl3945 后会加载 iwlwifi-3945-1.ucode 然后加载 iwlwifi-3945-2.ucode (API2)
这样就识别了。
启动系统的时候需启动/sbin/ipw3945d
更换firmware后,如果想要重新识别网卡,可以重新挂载一下内核模块
modprobe -r iwl3945
modprobe iwl3945问题是识别了但是网卡却不能up
查看网卡状态
ifconfig中没有wlan0
ifconfig wlan0 却是能显示wlan0的信息,这有些奇怪。
[sunshine@MagicLinux ~]$ iwlist wlan0 power
wlan0     Current mode:off
查看电源是关的,但是硬件开关是开的,我保证。[sunshine@MagicLinux ~]$ sudo iwconfig wlan0 power on
[sudo] password for sunshine:
Error for wireless request "Set Power Management" (8B2C) :
SET failed on device wlan0 ; Operation not supported.
[sunshine@MagicLinux ~]$ sudo iwconfig wlan0 txpower on
开启电源失败...此时监测message可以看到
iwl3945 0000:04:00.0: Radio disabled by HW RF Kill switch
总是说硬件开关关闭...我们看一下整体的启动信息。
[sunshine@MagicLinux ~]$ dmesg | grep 3945 --color

真是闷,每次都让我碰上这么闷的问题。
最后google发现
这个开关不太好用,需要用fn+F2开启,哦my god!Ubuntu 10.04中安装OpenCv2.1九步曲Ubuntu 10.04上实现在办公室远程监控家中电脑摄像头相关资讯      Linux教程
