Ubuntu 12.10 识别无线，但无法连接（英特尔迅驰 -N 1000）

这是我的问题，我刚刚安装了 Ubuntu 12.10，一切顺利，但是当我尝试连接到任何无线网络时，它保持连接状态，过了一会儿，它显示“无线网络断开连接 - 您现在处于离线状态”

太感谢了。

这是有关我的卡和其他东西的一些信息，我对这个主题确实不太了解：

答案1

我终于找到了解决方案！这里（帖子#5）

我所做的是，在“编辑连接...”中删除所有现有连接，然后手动添加无线网络。重启后它继续工作:)

谢谢大家的回复！它们帮了大忙

答案2

此问题有错误报告 (Ubuntu 12.10)：

NM 无法连接 Wi-Fi；dhclient 可以工作 - Intel Centrino Wireless-N 1000 iwlwifi

这表明 Ubuntu 无法发布系统配置此设备/驱动程序。

可能的解决方法：（来自帖子#40）

由于这个错误在 3.7.0-3 中更加严重，因此解决方法：

Startup Applications
Add
Title: Connect
command: ~/wl

其中 wl 是

#!/bin/bash
sudo iwconfig wlan0 essid LAUREL   { <-- your SSID }
sudo dhclient wlan0
exit 0

到目前为止，三双靴子都运行正常。

为什么 Ubuntu 无法发出 iwconfig？？

可能是您的网络路由器将您踢出。您是否检查过是否存在任何 IP 地址冲突，或者您的网络 ID 是否正确？以下是检查方法。

如果您有另一台计算机连接到运行 Windows（7）的网络，请打开网络和共享窗口。在窗口中查看您的活动网络。单击网络连接并查找您的 SSID，这就是网络 ID。在同一窗口的详细信息下，您应该看到 IPv4 地址。它通常类似于 192.168.1.100。当您返回到您的 Ubuntu 计算机时，单击右上角的网络图标，然后选择连接信息以显示您的 IP 地址。数字应该相似，但最后的数字必须不同（例如 Windows IP 192.168.1.100，Linux IP 192.168.1.102）如果它们匹配，您需要更改一个。要检查网络 ID，请单击网络图标并选择编辑连接。选择您的无线网络，单击编辑，然后应该显示 SSID。它必须与 Windows 计算机上的匹配。如果 IP 不同而 SSID 匹配，那么您遇到了一个我不熟悉的其他问题。

我找到了另一种解决方法ndiswrapper，即在 Ubuntu 中注入 Windows XP 驱动程序的工具。您可以从以下网址下载http://sourceforge.net/projects/ndiswrapper/files/latest/download?source=files 下载.tar.gz 文件后，将其解压到桌面并按照INSTALL文件中的所有说明进行操作。

有一段文字要求您ndiswrapper -l在终端中输入“”，并说您应该得到“ driver present, hardware present”。如果您得到类似“”的内容device (2001:3308) present (alternate driver: rtl8192cu)，请将备用驱动程序的名称（在本例中为“ rtl8192cu”）添加到/etc/modprobe.d/blacklist.conf 要执行此操作，只需在终端中输入

sudo gedit /etc/modprobe.d/blacklist.conf

并在新行中添加“ blacklist rtl8192cu”（rtl8192cu这是我拥有的驱动程序的名称，您应该输入您拥有的驱动程序的名称）。然后保存并重新启动。如果您正确遵循INSTALL文件中的所有说明，wifi 密钥将使用 Windows 驱动程序而不是 Linux 驱动程序。
