Compaq NX9010 Wireless Problem

I'm working on a laptop (compaq NX9010) for a friend that had a harddrive failure. I've installed a new harddrive, installed Windows XP pro and all the drivers, everything seems to be working ok, except the laptop has a on/off button for the wireless connection, I've tried everything I know but it won't turn off, also the icon for the wired connection has an x on it and I can't get it to connect even though the drivers are installed and system tells me everything is working properly. What am I missing. Thanks in advance for any help or ideas.
