Thanks, Andrew.  I downloaded the driver and  it did not work at first.  However, it ultimately was the one I needed.  The I found the Networking forum and the first posting was labeled "Read Me First" by a Rick K.  In it he listed steps to take if the OS had to be totally installed from scratch.  It listed various drivers and the order they should be installed in.  I found four items to reload/re-install from the list he posted and did it in the order suggested.  The Quickset would not install as I received a message the "This is not a supported system.  Setup cannot complete".   The wireless still did not  work after installing  the network driver (R155386) so I scanned the files that were loaded and got down to C:\Dell\Drivers\R155386\XP\Drivers and found the file DPInst32 (there's also a 64 bit one).  This is the driver package installer and after executing it, a series of drivers were installed and the WIFI light initiated.  Once I went to my networking set-up and set-up the wireless configuration, everything is now working and I have network access.  Thanks again for the replying so promptly and setting me on the correct path.   Roger
Due to a hardware problem I had to reinstall the operating system.  I am running Windows 7 on an Inspiron 9300.  The PC originally had XP on it but has been running Windows 7 for several years and when I attempted to reload the drivers from the OEM disk provided at purchase, I received error messages.  The Bluetooth light toggles on and off with the FN + F2 but the WIFI light, which worked before the OS reinstall, no longer comes on.  I cannot find the WIFI listed in my network listing.  Neither the driver for the Intel Mobile Chipset or the Wireless network drivers will install.  I get the message that the OS is different and on one of the install attempts a message that says "OS Section not found in INI file (iProInst.ini)".  Are there drivers available for the wireless network card that will work on Windows 7?  The original PC configuration shows that an Intel 2200 Wireless Mini PCI card was installed.  Any help or suggestions would be appreciated.
Wireless stopped working after OS install
