最近几个experimental内核下iwl3945网卡无法工作了

stesen

之前的2.6.34和昨天装的2.6.35都无法工作
lsmod可以看到模块,网卡设备也能识别,但就是无法扫描和连接ap

自己编译的2.6.35内核,可以驱动无线网卡,但是奇怪的是耳机插入后耳机没有声音,喇叭依然在响

装过了,不装的话,2.6.32下也没法用3945的

试试看这样行不？ 先下载这个压缩包

http://ncu.dl.sourceforge.net/pr ... 2/ipw3945-1.2.2.tgz

解压后，将 iwlwifi-3945-2.ucode 复制到 /lib/firmware

如果是使用wicd的话，记得在Preferences加上 Wireless interface: wlan0 后看能否扫描到AP？我昨晚才在 Dell Latitude 620 安装了 squeeze 版本，3945ABG也是抓的到，但不工作，后来就是这么搞定的。不过感觉还不是很稳定，仍在测试中。

上面给的链接不对，应该是

http://intellinuxwireless.org/iw ... ucode-15.32.2.9.tgz

后来的测试都很稳定没问题了。

后来发现是hp-wmi的问题, 去掉这个选项一切ok了
抱歉挖了个坑

种过一豆

firmware-iwlwifi这个软件包装上就可以的，我的也是3945的无线网卡，debian官方网站已经把这个问题说清楚了，缺少的东西官方打包成了一个压缩文件供有问题的下载
