![lubuntu 14.04 没有无线,iwconfig 显示卡两次](https://linux22.com/image/972620/lubuntu%2014.04%20%E6%B2%A1%E6%9C%89%E6%97%A0%E7%BA%BF%EF%BC%8Ciwconfig%20%E6%98%BE%E7%A4%BA%E5%8D%A1%E4%B8%A4%E6%AC%A1.png)
我刚刚在 Thinkpad T42(带 forcepae 选项)上安装了 Lubuntu 14.04。除了 wifi,其他一切都运行正常。小程序只显示附近的几个网络。如果显示我的家庭网络,它会要求输入密钥,但之后什么也不做。安全性设置为 WPA,因为该卡无法处理 WPA2。让我烦恼的是,iwconfig 显示两个相同的无线卡,一个为 ,eth0
一个为wifi0
。
iwconfig 输出是:
wifi0 IEEE 802.11-DS ESSID:“”

请注意,这里的逻辑名称是,wifi0
而网络管理器显示eth1
。有趣的是,我可以iwlist
在它们两个上使用扫描并查看至少一些附近的网络。我记得在 XP 中获取此卡的驱动程序非常痛苦,但它似乎在这里被正确识别。ifconfig
但是,使用 只会显示错误,并且eth1
那么,您知道这里发生了什么吗?
