Since you have the Dell Wireless Card you shouldn't of been able to install R171131 Intel Wireless. It seems like the Intel Application managed to install however. It is useless without the Intel adaptor so you will need to remove it.  [IMAGE] You should have an error like the above every time you log in. Go to Start > Control Panel > Add or Remove Programs. Select the Intel(R) PROSet/Wireless WiFi Software, select change and opt to remove it. [IMAGE] There might also be Dell Wireless somewhere, remove it also. Then reboot your machine. Then perform a clean with ccleaner. Next tap Fn and F2 and tap Fn and F2 again. Next try to install R189136 instead, this is an updated driver but not listed on the Inspiron 6400 drivers and downloads page. Hopefully you won't get the cpp error again. P.S. if there are no errors left and you have not installed a bluetooth card, it is likely you don't have one so I would not attempt installing any of the bluetooth drivers. So you have the following installed? Windows XP Standalone Service Pack 3 ✔ Internet Explorer 8 ✔ Windows Media Player 11 ✔ .Net Framework 2.0 ✔ R120775 Dell Notebook Software - Under Utility ✔ R114079 Intel Chipset - Under Chipset ✔ R141246 Ricoh Card Reader - Under Chipset ✔ R153830 Intel Graphics - Under Video* ? R128573 ATI Graphics - Under Video* ? R126007 nVidea Graphics - Under Video* ? R114200, R90851 Conexant Modem - Under Communication ✔ R149798, R150593 Broadcom Ethernet - Under Network ✔ R174291 Dell Wireless - Under Network ✘ (but try R189136) R120179 Synaptics Touchpad - Under Input ✔ R171789 Sigmatel Audio - Under Audio ✔ R157261 Dell Quickset - Under Applications ✔ Dell Support Centre Microsoft Security Essentials** * One of these should install, 2 should fail what one do you have?** Unless you have a preferred security program.
Had to reload Windows XP on my Inspiron 6400.  Now my PCI device, ethernet controller and network controller won't work.  Used my service tag # to bring up the Dell driver downloads for my PC but don't see any names or numbers that correlate to disabled divices.  Any suggestions???
