さて、以前からPepoLinuxで無線LANと思っていたが
[root@~]# tail /var/log/messages

[root@~]# iwconfig
lo no wireless extensions.

Warning: Driver for device wlan0 has been compiled with version 22
of Wireless Extension, while this program supports up to version 20.
Some things may be broken...

といかにも、無線LANが認識しているようなログメッセージと結果
しかしiwconfigで設定するとerrorとなる
[root@~]# iwconfig wlan0 channel 11
Error for wireless request "Set Frequency" (8B04) :
SET failed on device wlan0 ; Network is down.
でlogを確認するとなんや、zd1211rwのfirmware fileがないとおっしゃとる
Mar 17 13:24:42 (none) kernel: usb 2-1: Could not load firmware file zd1211/zd1211b_ub. Error number -2
