iwconfig表示工作的wifi卡“没有无线扩展”。
我想建立一个虚拟的无线网络接入点。为了找到我的接口名，我使用了iwconfig，它没有显示任何无线扩展，即使我可以使用我的无线网卡。
使用: Dell 1540 an驱动程序: Broadcom STA无线驱动程序(它是另一个驱动程序)
iwconfig结果：
lo no wireless extensions.
eth1 IEEE 802.11abg ESSID:off/any

你想把自己设为VPN？还是你想连接到其中一个？不管怎样，看起来你都错过了埃西德号。如果你试图建立一个超出我经验范围的虚拟专用网，但是对于you...not来说，有各种各样的包可以做到这一点，当然，对于任何开源的东西都是肯定的。查看论坛，因为这可能是一个问题已经得到回答。
如果您正在尝试连接，我相信问题是您没有输入SSID。我不知道你可以连接到一个虚拟专用网不做so...it将不会是非常私人的，否则。
参见此处设置SSID等：http://ubuntuforums.org/showthread.php?t=1062276

lspci输出显示，您有一个RealTek千兆网卡和一个宽频Wifi卡。
您的iwconfig输出显示，除了回送接口之外，您还有两个网络接口: eth0不是无线网卡，所以我想是Realtek和eth1是无线网卡，在运行iwconfig时没有连接到Wifi。
所以你的无线网卡叫做eth1。
