cubieboard能使用雷凌网卡吗？我在ifconfig wlan0 up 都启动不了。

0x88

请高手指点
系统报错如下：

root@cubieboard2:~# ifconfig wlan0 up
SIOCSIFFLAGS: No such file or directory

支持的。内核必须启用Ralink driver support，并选择好相应的模块；此外还要apt-get install firmware-ralink固件（for debian）

请问如何启用Ralink driver support啊?  lubuntu本来就有了雷凌的驱动，所以是不需要下载驱动的。就是不知道为什么起不来,用strace ifconfig wlan0 up时，出现了一个读不出的参数，如下所示

1. ls /sys/class/net/

复制代码

看看有没有wlan0这个设备

另外你的是USB无线网卡吧，插入后dmesg看看信息是什么。很多USB网卡都要驱动+固件(firmware)才能用的。

确实少了firmware,使用apt-get install linux-firmware就可以了。谢谢soloforce.
