解決 IPW2200 [Intel Pro/Wireless] wireless 未啟動 in IBM R50e

接續

Install Ubuntu 7.10 coexist with XP via wubi

發現 Wireless 沒法啟動
下command
nelsonchung@nelsonchung-laptop:~$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

eth1 radio off ESSID:""
Mode:Managed Channel:0 Access Point: Not-Associated
Bit Rate:0 kb/s Tx-Power=off Sensitivity=8/0

Power Management:off

發現 radio off
可見是硬體電路還沒給電的關係

參考tony說(from charles)
linux kernel 可以 identify N.B.' wireless card
用dmesg | grep 'ipw2200' or dmesg | grep "ipw2200"
[ 14.380000] ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.2.0kmprq
[ 14.380000] ipw2200: Copyright(c) 2003-2006 Intel Corporation

表示有
只是沒有fireware
去http://ipw2200.sourceforge.net/下 下載
點fireware直接下載fireware版本

解壓縮後 複製到/lib/modules/2.6.22-14-generic/kernel/drivers/pci/hotplug and lib/firmware
(locate hotplug 找到該目錄)
(原本tony大大是安裝在debian上 路徑為 /usr/lib/hotplug/firmware and lib/firmware)
重新開機

wired network還插著
wireless 的燈沒有亮
拔掉wired network 就沒辦法上網
修改
/etc/network/interfaces
from
===
auto lo
iface lo inet loopback
===
to
===
auto lo
iface lo inet loopback

auto eth1
iface eth1 inet dhcp
wireless-essid xxxx
wireless-key xxxx
===
ok
可以了
