我的电脑里有一个 Realtek RTL8188CE 802.11b/g/n WiFi 适配器。今天我升级到了 13.10，但无法连接。升级之前，WiFi 工作正常。我可以看到 WiFi 网络，但尝试连接时只会显示“IP 配置不可用”的错误。其他设备工作正常。我尝试删除配置并多次重新进行配置，但都不起作用。

因此，查看系统日志，似乎 DHCP 请求超时了。如果我手动设置 IP 和其他设置，我可以连接到网络，但我还没有通过 Wifi 连接互联网 - 我认为我的手动配置还有点问题。

这是 lspci：

chrisn@Zircon:~$ lspci | grep WiFi

以及来自 lshw -C 网络的输出

有人有主意吗？

答案1

我遇到了完全相同的问题，我找到了一个相当巧妙的解决办法：重新制作 Live CD。在安装好的 Ubuntu 上，我安装了Ubuntu 定制套件我曾经使用 UCK 定制 Kubuntu 13.10 的原始 ISO。基本上，UCK 会在 ISO 中 chroot，并允许您对其进行定制。我启动了 UCK，并要求它允许我访问控制台，然后我修改了 /etc/apt/sources.list，并添加了以下行：

deb http://archive.ubuntu.com/ubuntu/ saucy-proposed main restricted universe multiverse

以启用最新（不稳定）软件包的下载。然后我运行apt-get update和apt-get dist-upgrade，安装了其他软件包plasma-nm和其他与网络相关的软件包。然后我结束了 UCK 会话并构建了一个新的 ISO。如果我使用此自定义 ISO 启动系统，则 DHCP 不会超时，显然一切都正常。

如果有人感兴趣的话，我可以将我的 ISO 放在网上（只需发表评论，如果没有人使用，我不想上传 1GB），但是我建议您创建自己的 ISO，因为它很简单，你不必相信我并假设我没有篡改 ISO。

请注意，我只测试了实时系统，并没有运行完整安装。YMMV。

答案2

我在从每日构建 ISO 安装 13.10 时遇到了同样的问题。彻底升级系统解决了这个问题。

我遵循的步骤如下：

  • 使用以太网连接（因为手动配置无线很麻烦）
  • 运行dhclient eth0配置并确保接口已启动
  • 做apt-get update/apt-get dist-upgrade例行公事
  • 删除所有以前存储的无线连接
  • 重启

这为我解决了这个问题。但是，网络管理器时不时地会试图接管并取消配置连接，因此下载停止。我不得不取消下载，dhclient eth0再次运行，然后恢复 dist-upgrade。

我希望这个对你有用！

答案3

13.10 附带的驱动程序存在一些问题。它似乎越来越糟糕了。

如果你喜欢冒险，我拿了驱动程序源代码并自己修复了它。我把它发布在 Github 上： https://github.com/FreedomBen/rtl8188ce-linux-driver

到目前为止，这是我所知道的唯一一个可以在 Ubuntu 13.10 上编译和运行的驱动程序版本（除了预打包的版本）。文件中有安装说明README.md。

答案4

您可以尝试使用我制作的这个脚本将其放置在网络中：

斌/sh

.bin/sh nmcli nm sleep=false 'network' 中的案例 ![%] 结束案例

这样也许能很好地发挥作用。
