On a Dell Inspiration 1545 Laptop with a Broadcom 4312BG wireless chipset (I believe), the driver installed (stock from Dell), when I try to scan for available networks, nothing shows including mine that is three feet away. My other laptop in the same place sees four networks. I'm running XP pro w/sp3, No firewall or security software, No encryption, passwords etc., Device manage shows good, the connection shows in Networks with no issue. I originally tried the software included with the 'Dell' package which was a Intel program (??), but it couldn't find anything. Then I just tried the Windows program, but the same thing. Other than a broken cable(s) to the internal antenna, or a outright defective chipset, is there a Windows 'Service" if stopped would cause this to happen?
