Question

I have a compaq presario c700. I reloaded with xp pro. Everything works fine except the built in wireless. I can't get the wireless on. I have the amber light in both places were the wifi symbol is. I have downloaded more than 5 differents drivers but still don't work. I believe I have to turn the wifi on the bios but I don't see that option. Help please
