我尝试设置虚拟 wifi 接入点。为了找到我的接口名称，我使用了它iwconfig，但它显示没有无线扩展，尽管我可以使用我的 wifi 卡。
使用：Dell 1540 vostro 驱动程序：Broadcom STA 无线驱动程序（它是一个附加驱动程序）
iwconfig 结果：
lo no wireless extensions.
eth1 IEEE 802.11abg ESSID:off/any
Mode:Managed Access Point: Not-Associated
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
eth0 no wireless extensions.

您正在尝试将自己设置为 VPN？或者您正在尝试连接到 VPN？无论哪种方式，您似乎都缺少 ESSID。如果您尝试设置 VPN，这超出了我的经验范围，但有各种软件包可以为您做到这一点……但不确定是否有任何开源软件。查看论坛，因为这可能是一个已经回答过的问题。
如果您尝试连接，我认为问题在于您没有输入 SSID。我不知道如果不输入 SSID，是否可以连接到 VPN...否则，隐私性会很差。
请参阅此处了解如何设置 SSID 等： http://ubuntuforums.org/showthread.php?t=1062276

这串行通信输出显示您有一张 RealTek 千兆网卡和一张 Broadcom Wifi 卡。
你的系统配置输出显示除了环回接口之外，您还有两个网络接口：eth0，它不是无线网卡，所以我猜它是 Realtek 的；eth1，它是无线网卡，运行时没有连接到 Wifi AP iwconfig。
所以你的无线网卡叫做eth1。
