（参考：http://www.arm9home.net/read.php?tid-12194.html使用USB无线网卡和USB摄像头打造mini2440无线监控系统http://www.arm9home.net/read.php?tid-7237.html打造mini2440上的万能USB无线网卡工具包）
用人家做好的最新的内核mini2440-linux-image-20100925.zip包里的zImage_X35，插上USB无线网卡B-Link有以下信息：
usb 1-1: new full speed USB device using s3c2410-ohci and address4
usb 1-1: New USB device found, idVendor=0bda,【】 idProduct=8176
usb 1-1: New USB device strings: Mfr=1, Product=2,SerialNumber=3
usb 1-1: Product: 802.11n WLAN Adapter
usb 1-1: Manufacturer: Realtek
usb 1-1: SerialNumber: 00e04c000001
usb 1-1: configuration #1 chosen from 1 choice
然而scan-wifi之后，ifconfig并不能查看到wlan0信息。可见该内核也不能支持该无线网卡。
用TP-LINK的TL-WN322G+试一下：
[root@FriendlyARM /]# usb 1-1: new full speed USB device usings3c2410-ohci and address 3

便是漫长的等待。。
如果可以的话，ifconfig会出现以下信息：

ping192.168.2.145和联了网的PC机通信，可以看出联上了的信息。然而，在PC机输入telnet 192.168.1.5或ping192.168.1.5都没效果。
在也用无线网卡联同一局域网的PC机（IP地址：192.168.1.6）cmd：输入telnet192.168.1.5，可以远程控制开发板，但是速度很卡。效果不佳。
#ifconfig wlan0down可以断开网络连接。
