请问，解压后放置在什么地方？

[vickycq]

标准的Ubuntu安装应该已经包含 linux-firmware 这个包。

你这张网卡需要的固件为 iwlwifi-5000-*.ucode

可以执行下面命令确认

代码： 全选

ls /lib/firmware | grep iwlwifi-5000

没输出表示没有。
若没有，从这里下载你对应版本的包 手动安装之 (sudo dpkg -i linux-firmware_*.deb)
http://packages.ubuntu.com/search?keywo ... ection=all

或者从
http://linuxwireless.org/attachments/en ... .11.tar.gz
http://linuxwireless.org/attachments/en ... 4.2.12.tgz
http://linuxwireless.org/attachments/en ... .5.1-1.tgz
下载三个版本的固件解压缩 将 iwlwifi-5000-*.ucode 拷贝到 /lib/firmware


优先选择第一种方法(安装deb)，因为你貌似软件源配置有问题，先不去管它，先重点解决驱动问题。

是 debian哈，不是ubuntu.

[vickycq]

今天货到了，附带光盘驱动，安装后win7下面成功搞定，请问ubuntu平台，如何使用？

是 debian哈，不是ubuntu.

你前面说了ubuntu的。说错了？
Debian 需要安装 firmware-iwlwifi。
先安装 firmware-iwlwifi 并重启试试。若还不行，需重复13楼的步骤，第二步去掉。

参考 https://wiki.debian.org/iwlwifi

iw wlan0 connect MyCharterWiFi99-2G 2452
这个命令没有报错。
但是，用火狐浏览器无法连接到任何url.

没有安装/使用 NetworkManager？

断开无线连接，打开终端执行

代码： 全选

sudo tail -f /var/log/syslog

连接无线，将上面终端中刷出的信息 全部复制贴上来。

保持无线连接，在终端中执行

我的B电脑安装了pci接口的wifi接收器，A电脑的网址 192.168.1.100 ，A电脑连接的无线路由器，这个无线路由器的地址是 192.168.1.1
B电脑上执行

ping -c 3 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
From 192.168.1.100 icmp_seq=1 Destination Host Unreachable
From 192.168.1.100 icmp_seq=2 Destination Host Unreachable
From 192.168.1.100 icmp_seq=3 Destination Host Unreachable

192.168.1.100连接了192.168.1.1 ,为何B电脑无法连接上它？

胜利在望了！
1。驱动顺利安装了
2。可以scan到ssid ，表明可以接收信号了
3。链接的命令无报错
iw wlan0 connect -w MyCharterWiFi99-2G
4。最可能的问题就是网络的设置了

我问了老外，
http://superuser.com/questions/995404/h ... 406#995406
按照他的做，还是有问题，请高手看看，如何写这种情况下的配置。
谢谢

[pengsir]

问题解决了，最后是网络配置的问题。
请看
