如何搜索无线网络？

我正在使用 Ubuntu 12.04。我尝试过这个

sudo iwlist eth0 scan

但这似乎不起作用:(..它说“界面不支持扫描”该怎么办？请帮忙..我无法在 Ubuntu 上访问互联网。

我有移动宽带 USB，但连这个都检测不到。其他 U 盘都能检测到

更新：

请按照此问题先安装驱动程序。答案取决于内核版本。要了解您的内核版本，您可以执行uname -a

带有 3.4 / 3.5 内核的 Broadcom 4365 无线驱动程序

eth0不是无线适配器。它是以太网适配器。

尝试sudo iwlist wlan0 scanning | egrep 'Cell |Encryption|Quality|Last beacon|ESSID'

更好的是，首先使用硬件开关启用无线适配器。

然后单击顶部面板network manager按钮查看可用的网络。
