Wireless Radio On - No Wireless Network Option???

I have a Dell Latitude X300 laptop running XP Home Edition.  I lost the hard drive, put a new one in, got all the software installed and updated the drivers.  Now, I show that the wireless radio turns on and off and Device Manager shows it is working properly; however, there is no wireless option in "network connections" and I can't see my wireless hub/router.  Everything works great as long as my network wire is plugged in but I can't get anything wireless.  Any ideas?  How do I know that it's really working and if it is, shouldn't there be a "connect to wireless network" option in "network connections?"  Thanks.
