Please Help me,problem with downgrade

I just downgraded my Vaio labtop (VGN-FZ25S) from Vista To XP.and I have a problem with wireless. (Intel® PRO/Wireless 3945BG Network Connection).

the problem is .. I can not connect to the internet by using wireless. but I still can connect to the internet by LAN. I think the problem is about the switch wireless because it doesn't show the light when I open.( I think my driver is ok too)

I don't know how to fix it. Please heip me. I took two days to solve this problem but too bad it didn't work

 

simple....drivers issue! Get the latest drivers from Intel or Sony, and install....should sort it! Also try using the VAIO Smart Network utility (available from the Sony site)....might help?

I used this site http://www.sony-asia.com/support/do...g/sectionfirst?site=hp_en_AP_i&subpage=detail
for drivers. and followed the orders.
and I didnt' find VAIO Smart Network utility on Sony Website. Could you find the link for me?

 

I alse checked on " Wireless Swithch Setting". it just has only function " Enable Bluetooth Device".
I think it should have another funcion like " Enable Wireless Lan" but It don't have. What happen?
oh and I also tried to reinstall and install wireless lan driver already....but It still didn't work.
Please help me ....
