linux下几款usb无线网卡的使用

我最近要在龙芯福龙的盒子上使用无线网卡，盒子的接口很少，可以用的只有usb接口。市面上的usb无线网卡很多，下面只是几个简单的例子：

1：TP-LINK TL-WN322G+ 54M无线usb网卡

ubuntu默认是支持此芯片的，可以不用以下的内核编译和固件安装，

内核编译：

这个网卡的芯片组是ZyDAS ZD1211/ZD1211B wireless chip，在内核中要选上相关驱动：

? ZyDAS ZD1211/ZD1211B USB-wireless support

Prompt: ZyDAS ZD1211/ZD1211B USB-wireless support

Depends on: NETDEVICES && !S390 && USB && MAC80211 && WLAN_80211 && E

Location:

-> Device Drivers

-> Network device support (NETDEVICES [=y])

-> Wireless LAN

-> Wireless LAN (IEEE 802.11) (WLAN_80211 [=y])

安装firmware：

下载firmware

#tar xjf zd1211-firmware-1.4.tar.bz2

#cd zd1211-firmware-1.4

#mkdir /lib/firemware

#mkdir /lib/firemware/zd1211

#cp zd1211_* /lib/firmware/zd1211

固件安装和内核支持此芯片后，插入WL—322G＋后,

#dmesg|tail

机器已经识别了，可以使用了。

不过同其它的有线网卡使用不同，它要用wireless－tools来管理，

＃apt－get install wireless－tools

＃ifconfig eth1 up

#iwlist eth1 scan
