我的筆電是 thinkpad R50e 1834-A67,
不知從什麼時候開始 只要用 wireless 就會過一陣子斷線
即使訊號強度非常好 100% 也會斷
用ping AP IP address, 或pcman 開著 就可以reproduce.
它的wireless card 是 intel 2200b/g
我試過更新laptop wireless driver 都無效
原本出廠 driver 版本是 8.1.0.28
我曾試過升到9.0.4.39 (intel 網站的最後一版)
9.0.4.8 (Lenovo 網站上獨立driver 最新版)
package 11.05.0 (driver 9.0.4.37) 都沒有用
而且我都照指示先uninstall old driver, 所以整個測試起來很花時間....
而且這樣亂測的結果... 我的Fn + F5 都壞了 變不能開關 WLAN.

最後我就試著去upgrade AP firmware 了,本來不想走這一條路
我的AP 出廠firmware 大約是110930 這個日期前後的
(升完發現 reboot 根本都沒有換新
要斷電才有用)
同一時間因為我laptop Fn + F5 已經失效 我索性再 recovery 一次 (今天本來就從 factory default 開始, 因為要給我妹用)
結果laptop recovery 完,一測,就好了耶!!!
這時driver 仍然是 8.1.0.28 喔
提供給有類似問題的朋友。
更新:
這時我還沒有apply windows update, 目前我的OS版本是SP3 of XP Home.

Thinkpad R50e and TP-LINK 1043ND connection lose problem
If your laptop is Thinkpad R50e (1834-A67) which has Intel Pro 2200b/g as its wireless device, and you have TP-LINK 1043ND as your wireless AP.
If you have connection lose problem (even though radio strength is very high, 100%!), you can try the following way:
1. upgrade firmware of 1043ND to TL-WR1043ND_V1_120405.
Power cycle to have it effective.
2. Now, you should have no connection lose problem.
( I have do many tests. When my 1043ND firmware is TL-WR1043ND_V1_11xxxx (I don't remember the month and day of my default firmware),
I have changed wireless driver to 9.0.4.8, 9.0.4.37, 9.0.4.39. All of them cannot solve my problem.)
