这是我的配置： - SO：Ubuntu 12.04 - 内核：3.5.0-25 - 笔记本电脑：Sony Vaio VGN-FZ21E - WiFi 车：Intel PRO/Wireless 3945ABG [Golan] - 驱动程序：iwl3945
挂起后我的 WiFi 无法使用，即使重启网络或重新加载模块也是如此。这似乎只是因为卡被关闭了，Ubuntu 无法与其通信。我之所以这么想，是因为我查看了/var/log/syslog我发现了这个：

将内核升级到 3.5.0-25 后，我注意到一个名为无线上网，它也出现在系统日志中，并且他似乎与无线网卡有一个对话：

任何想法 ？！

以下是输出lspci-nn|复制代码：

命令ls /etc/modprobe.d | grep iwl给了任何东西....
2013.03.13
iwlwifi 不存在于 /etc/modules 中，但已成功添加到 /etc/modprobe.d/blacklist.conf。
我尝试了三次暂停并恢复，但第四次时问题又出现了。
ps 同样的问题也发生在内核 3.2 上，其中没有 iwlwifi。
重要提示：升级管理器建议我安装“网络管理框架（wifi 和移动的通用文件）”和“网络管理框架（wifi 和移动的 GNOME 对话框）”。我应该安装它们吗？它们到底有什么用？会影响我的问题吗？
2013.03.14
在文件中添加以下行/etc/pm/config.d/配置
SUSPEND_MODULES="iwl3945"
经过一些成功的测试后，问题出现了，Syslog 中出现了新的错误消息：

答案1
这里有一种方法有时很有效：
gksudo gedit /etc/pm/config.d/config
添加一行：
SUSPEND_MODULES="iwl3945"
校对、保存并关闭 gedit。重新启动、暂停并让我们收到您的报告。
答案2
驱动程序 iwl3945 适合您的设备；iwlwifi 不适合您。让我们看看它为什么加载并停止它。请执行以下操作：
gksudo gedit /etc/modules
如果其中有 iwlwifi，请将其删除。校对、保存并关闭 gedit。现在执行：
sudo su
echo "blacklist iwlwifi" >> /etc/modprobe.d/blacklist.conf
exit
现在重新启动并告诉我们它是如何工作的。
答案3
直到这个错误被修复之前我最常用的是这个：
sudo service network-manager restart
暂停后在终端中输入
我还没有尝试足够多次以确保它每次都能奏效，但我希望它能奏效
答案4
卸载 NetworkManager 并安装 wicd-gtk 尝试一下。
sudo apt-get 安装 wicd-gtk
确保卸载 NM。
如果没有起作用，请检查
杀戮
然后取消全部阻止
再次努力
