回复：I got confused... How about now?

The wireless used to work before I reinstalled the WinXP. Now, it showed excellent connection on the right bottowm corner of the desktop after I set it up, however, the browser (firefox or explorer) does not work, i.e. page is not found. When I instead use wire to connect to internet, the browser works just fine. Also, when I tried to repair the wireless, I got the info that repaire error, saying that unable to obtain IP address. Hope this is clear to you. I am at work, can not type Chinese.
