小弟發現使用加密的無線網路會當機
這種情形已經持續好一陣子了，只不過最近比較受不了了，所以才寫上來向大家請教
我使用加密的無線網路（tkip），是利用wpa_supplicant來進行
方法是先編輯一個檔案/etc/wpa_supplicant/Wireless.conf，內容如下：
network={
ssid="Wireless"
#psk="xxxxxxxxxxxxxxx"
psk=c6aekpxiqvrjkgmdfgkjsirc0dfnskldmnmvbncvbxcdfshtr8
}
然後以root下兩個指令：
wpa_supplicant -BDwext -i eth1 -c /etc/wpa_supplicant/Wireless.conf
dhclient eth1
通常上面這個兩步驟可以讓小弟順利上網
不過偶爾卻會讓整個Linux死當，這種情形特別常出現在那台AP剛開機不久或者AP當機時
這次我在AP剛開機時下了上述的指令，呈現如下訊息之後，我的Debian就立即死當了
There is already a pid file /var/run/dhclient.pid with pid 2761
killed old client process, removed PID file

如果可以正常連上的話，訊息會是如下

看來兩者最主要的差別是在最後兩行，不知各位前輩是否有遇過類似的問題呢？
我用的系統是Debian testing 核心2.6.18-4-486
無線網卡是intel-2200（ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.1.2kmq）
無線AP是ASUS（型號WL-530g，怪機子...，開機一段時間就會當掉，幾乎每天都要重開機）
如果小弟的訊息有不夠清楚或詳盡的，煩請告知，感謝不盡
