Fix trouble the Wireless LAN driver

This time I want to tell you about my experience when I was asked my boss to fix his Toshiba laptop. Suddenly, his Toshiba laptop cann't connect to his wifi connection at home. When I try to connect to wifi connection the laptop can detect its SSID but when I try to click button Connect, it cann't connect without error notification. He is using Linksys W54G Access Point
And then I try to reset the Acces Point password then force change password in laptop too after that's done, they still cann't connected. Because the setting Access Point encryption had configure to WPA then I guess that Wifi driver on laptop doesn't recognize WPA yet so I change the Access Point encryption to WEP and I restart the laptop and Access Point and then retry again to connect between laptop and Access Point and the result is very disappointed for me because they still cann't connected.
Arhhhhhhhhhggg..........
Finally, I open Control Panel - System, click Hardware tab, click Device Manager button and I am looking for Wifi driver then I uninstall its driver (The idea is to refresh the driver files) through right click on driver name and then choose Uninstall menu then close Device manager window, restart your computer.
And Windows XP will detect and found your Wifi device as new hardware and Windows will install driver automatically (the result is vary, maybe Windows XP will ask for driver) and when they're finshed. At last, I retry to connect to Access Point and it's works !!
And I set back the Access Point encryption mode to WPA and try to reconnect it and they can connect and work properly.
If you get a same problem with me maybe you can try this solution......
